Description
The Testo 835-T2 is a professional non-contact infrared thermometer built for Australian HVACR technicians, maintenance engineers, and industrial quality control teams who need to measure extreme temperatures — up to 1500°C — safely and accurately from a distance. Whether you’re monitoring furnace walls, inspecting refractory linings, checking heat exchanger surfaces, or verifying air conditioning and ventilation system temperatures, the 835-T2 delivers precise, repeatable readings without putting you in harm’s way.
The 50:1 optics ratio and 4-point laser targeting system ensure you’re measuring exactly the right spot, even at distance. Onboard memory for 200 readings and free PC software make data capture and reporting straightforward on site and back at the office.

Who Is the Testo 835-T2 For?
The 835-T2 is the right choice when you need to measure temperatures well beyond the range of standard IR thermometers — up to 1500°C — and when measurement distance and spot-size precision matter. It suits industrial maintenance teams working around furnaces, kilns, and high-temperature process equipment, as well as HVACR technicians who need a single instrument that covers both standard HVAC surface temperatures and extreme heat sources. If your work stays within the −30 to 350°C range, a standard IR thermometer may be more cost-effective; the 835-T2 is the tool when you need the full industrial range.
Key Features
- Temperature range to 1500°C — covers extreme industrial and HVACR measurement requirements
