Product Description

Keen pH Test Kit is a wide-range colorimetric test kit used to determine the acidity or alkalinity of water. Model RMR-2002 covers a pH range of 4.0 to 10.0 and is intended for routine testing in laboratories, water-treatment operations, aquaculture, agriculture and industrial settings.

The test uses a pre-prepared liquid reagent. After four drops are added to a measured 5 ml water sample, the developed colour is compared with the supplied pH colour card. This provides a quick visual reading without the calibration, electrode maintenance or power requirements associated with an electronic pH meter.

One unopened kit contains enough reagent for approximately 400 tests when used according to the supplied instructions. The manufacturer states a five-year expiry period from the manufacturing date for an unopened reagent bottle kept under proper storage conditions.

Product Overview

pH is a numerical scale used to describe whether water is acidic, neutral or alkaline. A lower pH indicates greater acidity, while a higher pH indicates greater alkalinity. Monitoring pH helps users identify changes caused by chemical treatment, contamination, biological activity or process conditions.

The Keen RMR-2002 offers a practical alternative for frequent checks where a calibrated digital meter is unnecessary or inconvenient. It is especially useful for screening and routine process monitoring, but it should not replace an appropriate laboratory or instrumental method where highly precise or legally reportable data is required.

Key Benefits

Quick Visual Reading

The colour develops in approximately 10 seconds after the reagent is mixed with the sample. The user can then compare the result directly with the supplied colour card.

Wide Routine Testing Range

The pH 4.0-10.0 scale covers acidic, near-neutral and alkaline water conditions encountered in many routine water-testing applications.

High Test Capacity

Approximately 400 tests can be performed from one kit when the stated sample volume and reagent dose are followed.

No Meter Calibration Required

The colorimetric method does not require an electrode, battery, calibration buffer or digital display. This simplifies field checks and frequent screening.

Compact Complete Kit

The package includes the reagent solution, test tube, colour card and instruction manual needed to perform the test.

Who Should Buy This Product?

• Water-treatment plants and service companies
• Fish farms, hatcheries and aquarium maintenance teams
• Agricultural farms and hydroponic growers
• Swimming-pool maintenance professionals
• Industrial production and utility departments
• Quality-control and water-testing laboratories
• Schools, colleges, universities and research institutions
• Environmental field teams and development organisations
• Government, private and institutional procurement departments

Usage and Handling Summary

Follow the current instruction manual supplied with the product. The standard test procedure is summarised below:

• Rinse the test tube with clean water before testing.
• Fill the test tube with 5 ml of the water sample.
• Add four drops of the pH reagent solution slowly to the sample.
• Close or hold the tube securely and swirl it to mix thoroughly.
• Wait approximately 10 seconds for complete colour development.
• Compare the developed colour with the supplied pH colour card.
• Record the closest matching pH value.
• Rinse the test tube with clean water after completing the test.

Handling Precautions

• Keep the kit out of the reach of children.
• Keep the reagent away from heat, strong light and direct flame.
• Avoid contact with skin and eyes.
• Rinse the affected area with plenty of water after accidental contact.
• Keep the reagent bottle tightly closed when it is not in use.
• Dispose of used samples and chemical residues according to applicable laboratory and local requirements.
• Use under laboratory or technically competent supervision where appropriate.

Limitations and Important Considerations

• The kit only reads within the pH range of 4.0 to 10.0. Samples outside this range cannot be measured accurately with this colour card.
• The result is a visual colour match rather than a high-resolution digital reading.
• Strongly coloured, cloudy or turbid samples may interfere with colour interpretation.
• Lighting conditions and individual colour perception can affect the selected reading.
• The kit is intended for aqueous samples. Compatibility with concentrated chemicals, solvents or non-water liquids has not been verified.
• The stated five-year expiry applies to an unopened bottle stored under proper conditions. Follow the expiry date and storage instructions printed on the supplied batch after opening.
• Regulatory, legal, medical or high-precision laboratory decisions may require confirmation using a calibrated instrument or an accredited laboratory method.

Frequently Asked Questions

What does the Keen RMR-2002 pH Test Kit measure?

It measures the acidity or alkalinity of water over a pH range of 4.0 to 10.0. The result is obtained by comparing the developed sample colour with the supplied pH colour card.

How do I use the Keen pH Test Kit?

Fill the test tube with 5 ml of water, add four drops of reagent and swirl the tube to mix. Wait about 10 seconds, then compare the developed colour with the pH colour card.

How many tests can be performed with one kit?

One RMR-2002 kit provides enough reagent for approximately 400 tests. The exact number depends on using the specified four-drop dose for each test.

What pH range does the kit cover?

The kit covers pH 4.0 to 10.0. It is suitable for routine acidic, neutral and alkaline water checks within that confirmed range.

Can the kit be used for aquarium and fish-farm water?

Yes, the kit can be used for routine pH monitoring in aquariums, hatcheries and fish-farming systems. The required pH target depends on the species and operating conditions, so users should follow their own water-management guidelines.

Can it be used for drinking water, pool water or wastewater?

Yes, it can be used for routine screening of drinking water, pool water and wastewater when the expected value falls within pH 4.0-10.0. Formal compliance testing may require a calibrated instrument or accredited laboratory method.

What is included in the Keen RMR-2002 kit?

The confirmed package includes one 45 ml reagent bottle, one test tube, one colour comparison card and an instruction manual. Contact Inaya Scientific to confirm the contents of the current supplied batch before ordering.

What is the shelf life of the Keen pH Test Kit?

The manufacturer states a five-year expiry period from the manufacturing date for an unopened bottle stored properly. After opening, follow the expiry date and storage instructions printed on the reagent bottle and contact Inaya Scientific when clarification is needed.

What is the difference between this kit and a digital pH meter?

This kit gives a visual colour-card result and does not need calibration, batteries or electrode maintenance. A digital pH meter can provide a more detailed numerical reading but requires correct calibration, cleaning and storage.

Where can I buy the Keen pH Test Kit in Bangladesh?

You can order the RMR-2002 kit from Inaya Scientific, subject to current stock availability. Bulk and institutional quotations are available on request, with nationwide delivery across Bangladesh.

Closing Recommendation

The Keen RMR-2002 pH Test Kit is a practical option for routine water testing where a quick visual result is preferred.
