Temperature Meter Unit UT300S infrared thermometer, measurement range -50 to 300°C

The Unit UT300S infrared thermometer is a handheld temperature meter designed to measure surface temperatures without contact, covering a range from -50 to 300°C. The device provides fast spot readings using infrared sensing, enabling temperature checks where safety, hygiene or accessibility limit the use of contact probes. Its compact form factor and simple point-and-shoot operation make it suitable for quick diagnostics and routine checks across multiple environments.

Advantages

The infrared thermometer delivers rapid readings with a wide measurement range, allowing checks from low sub-zero temperatures to high surface heat. Non-contact measurement reduces risk of contamination or burns and allows safe distance operation. The instrument’s handheld design and intuitive controls support quick deployment for troubleshooting and preventive maintenance. Clear numeric output and stable response time help identify hotspots and temperature deviations efficiently.

Suitable for

• HVAC inspection and duct temperature checks
• Electrical equipment and motor surface temperature monitoring
• Engine bay and exhaust surface checks
• Kitchen and food-service surface temperature verification (non-contact)
• Maintenance, troubleshooting and preventive inspections

Key specifications

• Measurement range: -50°C to 300°C
• Measurement method: infrared non-contact surface measurement
• Form factor: handheld gun-style unit
• Response: fast spot readings suitable for quick checks
• Display: numeric readout for instant temperature indication

How to use

Point the UT300S at the surface to be measured from a suitable distance, keeping the optical axis aligned with the target. Pull the trigger or press the measurement button to initiate a reading and observe the numeric temperature on the display. For best results, ensure the measured surface is within the thermometer’s specified range and free of obstructions such as steam or reflective coatings that can affect infrared readings. Allow the instrument to acclimate to ambient conditions if moving between significantly different environments.

Usage recommendations

Use the thermometer for spot checks rather than continuous monitoring; place the target centrally in the instrument’s field of view and avoid measuring through transparent barriers. For highly reflective or polished surfaces, consider using a non-reflective tape or paint patch on the surface to improve accuracy. Store the unit in a dry, room-temperature environment and follow manufacturer guidance for battery replacement and basic cleaning.
