Value VIT-300 Infrared Thermometer (-18°C / +280°C, ±2°C Accuracy, 500 ms)

The Value VIT-300 is an infrared thermometer designed for non-contact temperature measurement. It takes a reading in 500 milliseconds without touching the surface, in the -18°C to +280°C range; it is well suited to quickly scanning suction and discharge lines, compressor bodies, condenser/evaporator surfaces and panel temperatures in air conditioning and refrigeration service. Weighing only 185 grams, it fits in a pocket and gives an instant result at the press of a button.

Fast, Non-Contact Surface Temperature Measurement

Using a contact probe on rotating, electrical or hard-to-reach parts is both slow and risky. With a 0.95 emissivity setting and 0.1 degree resolution, the VIT-300 takes readings from HVAC surfaces (tubes, ducts, motor housings) from a safe distance; with ±2°C (or ±2%) accuracy, it gives reliable results for service diagnosis.

Key Technical Features and Equipment

• Wide Measuring Range: -18°C / +280°C — one device from frozen lines to a hot discharge tube.
• Fast Response: Instant scanning with a 500 ms response time.
• 0.1 Degree Resolution: Shows even small temperature differences.
• 0.95 Emissivity: Fixed emissivity optimized for painted metal, plastic and insulation surfaces.
• Light and Compact: 185 g — takes up little space in the toolbox.
• Standard 9V Battery: Runs on a single, widely available battery.

Technician Tips

• Shiny/bare metal surfaces mislead infrared measurement; stick matte tape on such surfaces and measure on the tape.
• For an accurate reading, bring the device as close to the surface as possible; as the distance increases, the measured area grows and an average is taken.
• For jobs requiring precise calibration (such as adjusting the refrigerant charge), verify the infrared scan with a contact clamp probe.
