Product Description
Digital Thermometer TP101 is a portable probe-type thermometer designed for direct temperature checking across a wide listed range of -50°C to +300°C. The long metal probe allows the sensing tip to be inserted into compatible foods, liquids, semi-solid materials and prepared laboratory samples while the digital display remains outside the material being measured.
The TP101 format is commonly supplied with an easy-to-read LCD and simple control buttons for power, Celsius/Fahrenheit selection, reading hold and maximum/minimum temperature review. These functions support quick spot measurements in kitchens, food-processing areas, educational laboratories, workshops and other general monitoring applications.
This listing identifies ON as the brand, China as the country of origin, current stock as available and a one-year warranty period. Warranty eligibility, exclusions and replacement conditions should be confirmed from the Inaya Scientific invoice and supplied warranty terms.
The thermometer is intended for spot-checking. It should not be left continuously inside a hot oven, furnace, pressure vessel or other process unless the supplied product instructions specifically approve that application. Only the stainless-steel probe should contact the sample; the plastic display body is not intended for immersion.

Product Overview
A digital probe thermometer measures temperature through a sensor located near the tip of a metal probe. When the probe reaches thermal equilibrium with the sample, the electronic circuit converts the sensor response into a numerical value shown on the LCD.
Measurement speed and accuracy can be affected by insertion depth, probe position, sample movement, temperature gradients, contact with container walls, ambient conditions and the difference between the probe temperature and the sample temperature. A stable reading should be obtained before the value is recorded.
The TP101 is useful where a compact, battery-powered thermometer is preferred over a glass thermometer. However, it is not automatically a calibrated reference thermometer, medical thermometer or data-logging instrument. Applications requiring traceable accuracy should use a calibration certificate or comparison against a suitable reference instrument.

Main Applications
Food Preparation and Cooking
Suitable for spot-checking the internal temperature of compatible foods, sauces, beverages and cooking ingredients. Food-safety decisions should follow the applicable approved temperature requirement and proper probe placement.
Laboratory and Educational Use
Useful for general laboratory demonstrations, solution-temperature checks and supervised experiments where the expected temperature falls within the stated range and screening-level measurements are acceptable.
Liquid Temperature Measurement
Can be used for water, milk, tea, coffee, oil and other compatible liquids. Keep the display body dry and do not allow the probe tip to touch the side or bottom of the container when the objective is to measure the liquid itself.
Food Processing and Quality Control
Supports routine spot checks during preparation, cooling, storage, heating and processing. Where records are required for a quality system, the instrument should be identified, checked and calibrated at suitable intervals.
Agriculture and General Field Work
May be used to check compatible soil-water mixtures, stored products, compost extracts, greenhouse solutions and other non-corrosive samples. Direct use in corrosive chemicals or electrically live equipment is not recommended.
Industrial and Workshop Checks
Can support preliminary contact-temperature checks of suitable materials and liquids. It is not a substitute for a thermocouple, infrared thermometer or fixed process sensor when remote measurement, rapid moving surfaces, very high heat or continuous monitoring is required.

Basic Operating Procedure
The following is a general procedure. The instructions supplied with the current TP101 unit must take priority.
- Inspect the thermometer, probe and display for damage before use.
- Clean and disinfect the metal probe using a method suitable for the intended sample.
- Press the ON/OFF button and select °C or °F as required.
- Insert the probe tip into the representative part of the sample.
- Avoid touching the container wall, base, bone or another surface that can distort the reading.
- Wait until the displayed temperature becomes reasonably stable.
- Use HOLD when required to retain the displayed value after removing the probe.
- Record the reading together with the sample identification, date and operator where traceability is required.
- Clean and dry the probe after use, then switch off the thermometer.
Good Measurement Practice
- Use a consistent insertion depth for comparable measurements.
- Measure the thickest or most representative location in food or semi-solid material.
- Stir liquids gently where appropriate to reduce temperature gradients.
- Allow sufficient time for the sensor to respond and the display to stabilise.
- Do not measure by touching the probe only to the surface when an internal temperature is required.
- Check the thermometer periodically against a known reference point or calibrated standard.
- Repeat an unexpected reading after cleaning the probe and selecting a new measurement location.
- Record calibration checks when the thermometer is used in a controlled quality system.
Factors That Can Affect the Reading
- Insufficient probe insertion depth
- Contact with the wall or bottom of a container
- Temperature gradients within the material
- Reading before the display becomes stable
- Low battery or intermittent battery contact
- Damaged, bent or contaminated probe
- Rapid movement between extremely different temperatures
- Use outside the stated -50°C to +300°C range
- Electromagnetic interference or electrically live surfaces
- Lack of calibration where traceable accuracy is required
Cleaning and Maintenance
- Switch off the thermometer before cleaning.
- Wipe the stainless-steel probe with a clean damp cloth or suitable food/laboratory-safe disinfectant.
- Do not immerse the LCD body, buttons or battery compartment in water.
- Do not use abrasive pads that can damage the probe surface.
- Dry the probe thoroughly before storage.
- Remove leaked batteries immediately and clean the compartment safely.
- Replace the battery when the display becomes weak or unstable.
- Store the unit with the probe protected from bending or impact.
Storage
Store the TP101 in a clean, dry location protected from direct sunlight, high humidity, dust, corrosive vapours and mechanical impact. Keep it away from children and untrained users. Do not store the thermometer while the probe is wet or contaminated.
When the instrument will not be used for an extended period, remove the battery if recommended by the supplied instructions to reduce the risk of leakage. Exact storage limits should be confirmed from the current product manual or packaging.
Safety and Handling
- The metal probe has a sharp point; handle and store it carefully.
- Keep the display body and battery compartment away from water and steam.
- Do not place the complete thermometer inside an oven, microwave oven or pressure vessel.
- Do not use the thermometer on live electrical conductors or circuits.
- Avoid direct contact with corrosive acids, alkalis, solvents or materials that can attack the probe.
- Use suitable heat-resistant gloves when measuring hot samples.
- Clean the probe before and after food contact to reduce cross-contamination.
- Do not use this product as a clinical body thermometer unless the supplied instructions specifically approve medical use.
- Dispose of used batteries according to local regulations.
Important Limitations
- The TP101 is intended mainly for spot measurement and not continuous unattended monitoring.
- The plastic display body is not waterproof unless the supplied product label specifically states otherwise.
- The device should not remain inside an oven or high-temperature chamber during operation.
- Exact accuracy, response time, resolution, probe length and battery specification can vary between TP101 production versions.
- A standard retail unit may not include a traceable calibration certificate.
- The listed -50°C to +300°C range does not guarantee equal accuracy across the full range.
- Surface measurements may differ from internal temperatures.
- Warranty does not normally cover misuse, impact, liquid entry, corrosion, battery leakage or operation outside instructions; confirm the written terms.
