Non-contact laser thermometer Habotest HT650A, temperature range -50 to 650°C, infrared handheld

The Habotest HT650A is a non-contact infrared laser thermometer for fast surface temperature readings from a distance. With a measurement range of -50 to 650°C, the handheld device is designed for quick checks in HVAC, automotive, industrial inspections and kitchen applications where touch-free measurements reduce contamination risk and improve safety. Laser targeting assists accurate aiming at specific spots on surfaces.

Advantages

The Habotest HT650A provides a wide temperature range suitable for low-temperature refrigeration checks and high-temperature surface measurements. Its non-contact infrared sensing allows safe measurement of moving, hot or hard-to-reach objects without physical contact. Laser targeting improves aim precision, and the compact handheld design supports portability and one-handed operation in field use.

Suitable for

• HVAC system maintenance and duct temperature checks
• Automotive diagnostics and engine surface temperature readings
• Industrial equipment inspection and preventive maintenance
• Kitchen surface and appliance temperature verification
• Quick troubleshooting where non-contact measurement is required

Key specifications

• Measurement type: non-contact infrared thermometer
• Temperature range: -50 to 650°C
• Targeting aid: built-in laser pointer for aiming
• Form factor: handheld, pistol-style design
• Output: instant surface temperature readout

How to use

Point the Habotest HT650A at the surface whose temperature you need to measure, using the laser pointer to aim at the desired spot. Keep the device at an appropriate distance so the measured area corresponds to the target; press the measurement trigger to obtain an instant temperature reading displayed on the screen. For consistent results, avoid measuring through transparent surfaces and ensure the target surface is free from heavy steam or dust that may affect infrared readings.

Usage recommendations

For best accuracy, allow the thermometer and the target to reach stable temperatures when moving between environments with large temperature differences. Use the laser pointer only for aiming—do not stare into the beam. When measuring very reflective or shiny surfaces, consider applying a non-reflective tape or coating to the spot and measure that area to improve reading reliability.
