Product Overview

Thank you for purchasing the thermal imager. To use this product safely and correctly, please read this manual thoroughly. We suggest keeping the manual in an easily accessible place for future reference.

• TR256C is a handheld thermal imager with Laser Distance measure and GPS function.
• When the laser measure is switched on, the real-time distance between the Thermal Imager and the laser spotted target is displayed on screen, serving for keeping safe distance and thermal reading compensation. Maximum laser distancing range is 20m.
• The GPS function of TR256C enables latitude and longitude to be displayed on screen and auto-saved with images, no need for manual record. Note: the GPS function can only be applied outdoors.
• A 3.5" high-definition IPS screen displays a large investigation area, making it easy to pinpoint faults. A 55.6° wide angle of view covers a large thermal observation area compared to a normal lens. It is easy to survey an electric cabinet just 1m away, or heated floor in a narrow room.
• Equipped with a 256x192 resolution IR and 2MP visible light dual camera mode, TR256C can set the imaging ratio of infrared and visible light according to different needs. The personalized setting of emissivity ensures more accurate detection data.
• Built-in WiFi enables convenient connection with a computer for image sharing and projection.
• Within its detection range from -20°C to 550°C (-4°F to 1022°F), the TR256C thermal camera automatically detects hot, cold, and center temperatures, auto-tracks hot and cold spots, and auto-locks the highest and lowest temperatures. Adjustable low- and high-temperature alarm thresholds are very convenient for different applications.
• It can shoot and save images to the SD card. Data can be exported via TYPE-C connection even when the TR256C is power-off or used as an SD card reader. The built-in 5000mA rechargeable Li-ion battery is recharged by TYPE-C cord for long hours of running time.
• TR256C is IP65 water resistance and dust proof for tough jobsites. TR256C's LED flashlight can be applied to various dark environments for site perception and personnel safety. This thermal imager is perfect for Home Inspections, Missing Insulation, Air Leaks, Water Damage, Facility Maintenance, HVAC Troubleshooting, and professional inspections of electrical and mechanical systems.
