Product Description

The Lactometer Ordinary is a simple floating instrument designed to measure the relative density or specific gravity of milk. It is commonly used as a preliminary milk-quality screening tool in dairy farms, milk collection centres, educational laboratories and small-scale milk-processing facilities.

A lactometer does not directly measure fat percentage or prove the complete purity of milk. It measures how deeply the instrument floats in the sample, which provides an indication of the milk’s density. The result may help identify unusual density or possible dilution, but it should be interpreted together with temperature, fat testing and other milk-quality tests. The Food and Agriculture Organization identifies the lactometer test as a simple method for measuring the specific density of milk.

Based on the supplied product images, this model features a transparent glass stem, visible printed scale, enlarged glass bulb, dark weighted lower section and a blue plastic protective case. Its compact, traditional design makes it suitable for routine manual testing where a digital milk analyser is not required.

The exact measurement range, graduation, calibration temperature, tolerance and accuracy must be confirmed from the supplied instrument or manufacturer’s documentation before use in regulated or commercial quality-control work.

Product Overview

A lactometer is a specialised type of hydrometer used for milk. When placed in a suitable milk sample, it floats at a level determined by the density of the liquid. The scale reading is then used to assess the milk’s relative density.

The Bureau of Indian Standards describes lactometers as instruments for determining the specific gravity of milk. Its current standard covers a reference range of 1.020 to 1.035 at 27°C for compliant instruments, but this range must not be assumed for the supplied ordinary model until the actual scale is checked.

Temperature influences milk density and therefore affects lactometer readings. The result should be taken at the instrument’s specified calibration temperature or corrected according to the applicable test method.

The lactometer should be used as a screening instrument rather than as the only basis for accepting or rejecting a milk sample. FAO guidance recommends interpreting lactometer readings alongside other tests, particularly fat testing, because removal of fat, addition of water or addition of solids may affect density in different ways.

Main Applications

Preliminary Milk-Density Testing

The lactometer is used to obtain a quick relative-density reading from a milk sample. This can support routine milk-receiving and basic quality-screening procedures.

Screening for Possible Water Addition

Water addition generally reduces the density of milk, so an unexpectedly low reading may indicate possible dilution. However, the result is not conclusive by itself because temperature, milk composition and other forms of adulteration can also change the reading.

Dairy Farm Testing

Dairy farmers and milk collectors can use the instrument for preliminary sample assessment before milk is accepted, stored or transported.

Milk Collection Centres

The lactometer may be used for rapid manual checks during milk collection, especially where advanced electronic analysers are unavailable.

Food and Dairy Laboratories

It can support basic density-testing demonstrations and routine non-regulatory screening in dairy and food-testing laboratories.

Educational Demonstrations

The instrument is suitable for demonstrating density, buoyancy, hydrometer operation and basic milk-quality evaluation to students.

Small-Scale Milk Processing

Small dairy-processing facilities may use it as part of an initial receiving inspection, together with sensory, acidity, fat and microbiological tests.

Key Benefits

• Provides a quick preliminary milk-density reading
• Operates without electricity
• Lightweight and portable
• Easy to use after proper training
• Suitable for field and laboratory environments
• Reusable with correct cleaning and storage
• Protective case helps reduce damage during transportation
• Offers a low-cost alternative for basic density screening
• Useful for educational and practical dairy-testing activities
• Can support early detection of unusual milk density

Important Testing Limitation

A lactometer does not directly measure:

• Milk fat percentage
• Protein percentage
• Lactose percentage
• Total bacterial count
• Acidity
• Chemical contaminants
• Antibiotic residues
• Complete milk purity
• Every type of adulteration

A normal-looking lactometer reading does not guarantee that the milk is unadulterated or safe. For a more complete assessment, the reading should be combined with relevant fat, solids-not-fat, acidity, organoleptic, microbiological or instrumental tests. FAO specifically presents lactometer testing as one of several simple milk-quality tests rather than a complete standalone analysis.

How to Use the Lactometer

Prepare the Milk Sample

Mix the milk sample gently to create a uniform composition. Avoid vigorous shaking because foam and trapped air bubbles may affect the floating position.

Fill a Suitable Cylinder

Pour enough milk into a clean, tall lactometer cylinder so that the instrument can float freely without touching the bottom.

Check the Sample Temperature

Measure and record the temperature of the milk. Compare it with the calibration temperature stated on the lactometer or manufacturer’s instructions.

Lower the Lactometer Carefully

Hold the instrument by the upper stem and lower it gently into the milk. Do not drop it into the cylinder because the glass may break.

Allow It to Stabilise

Wait until the lactometer stops moving and floats freely. Ensure that the bulb or stem is not touching the sides of the cylinder.

Take the Reading

Read the scale at the correct meniscus position specified by the instrument or testing standard. BIS specifies top-of-meniscus reading for lactometers covered by IS 9585:2021, but the instructions for the exact supplied unit should take priority.

Record the Result and Temperature

Write down both the lactometer reading and sample temperature. Apply temperature correction only according to a recognised method or the manufacturer’s guidance.

Compare With Applicable Standards

Evaluate the corrected result using the standard, specification or quality-control procedure applicable to the milk type and testing location.

Interpreting the Reading

A lower-than-expected density reading may suggest water addition, high fat content or another compositional difference. A higher-than-expected reading may be associated with fat removal, addition of skim milk, higher non-fat solids or other changes.

FAO reports that the typical specific gravity of milk may be around 1.028 to 1.033 when measured at approximately 15°C or 20°C, but this is only a general reference. Milk species, composition, temperature, processing and applicable national standards must be considered.

Do not use a single general reference range to make a final decision without confirming:

• Milk type
• Sample temperature
• Lactometer calibration
• Applicable test method
• Fat percentage
• Solids-not-fat content
• Local regulatory requirements

Frequently Asked Questions

What is a Lactometer Ordinary?

A Lactometer Ordinary is a simple floating glass instrument used to measure the relative density or specific gravity of milk.

Does a lactometer measure milk fat?

No. A lactometer measures density, not fat percentage directly. A separate fat test is required for fat measurement, and FAO guidance recommends combining density and fat results for better interpretation.

Can it detect water added to milk?

It can help identify an unusually low milk-density reading that may be associated with added water. However, the result is not conclusive and must be interpreted with temperature and other quality tests.

What is included with this product?

The supplied images show one glass lactometer and a blue two-piece protective case. Confirm whether a testing cylinder or any additional accessory is included before ordering.

What is the measurement range?

The exact range is not clearly readable from the supplied images. Contact Inaya Scientific for confirmation from the available instrument.

Is the lactometer made of glass?

Yes. The product shown in the supplied images has a transparent glass stem and bulb.

Does it require a battery?

No. It is a manual floating instrument and does not require a battery or electrical power.

Is a separate cylinder required?

A suitable tall cylinder is normally required so the lactometer can float without touching the bottom or sides. Confirm whether the cylinder is sold separately.

Can it confirm that milk is completely pure?

No. It provides only a density reading. Complete milk-quality assessment may require fat, SNF, acidity, microbiological and adulteration-specific testing.

Is temperature important during testing?

Yes. Milk density changes with temperature, so the sample temperature and instrument calibration temperature must be considered.

Can it be used for commercial milk acceptance?

It may support preliminary screening. Commercial or regulatory decisions should follow the applicable standard method and use an appropriate verified or calibrated instrument.

How should it be stored?

Clean and dry the lactometer after use, then store it inside the supplied protective case in a safe location.

The Lactometer Ordinary is a practical and economical instrument for preliminary milk-density testing in farms, milk collection centres, classrooms and dairy laboratories.

Its glass construction, printed scale, weighted bulb and protective case make it suitable for routine manual use. However, buyers requiring a specific range, calibration temperature, accuracy or certification should confirm those details before ordering.
