    Testo 835-T2 Infrared Thermometer

    PLEASE NOTE: Not all infrared thermometers are suitable for accurately measuring body temperature or detecting fevers (such as those commonly associated with COVID-19 or Influenza).

    For applications such as these we recommend the 8836M Non-Contact Forehead Ir Thermometer or Extech IR200.

    If in doubt please contact our Sales Department at 0113 248 9966.


    The Testo 835-T2 Infrared Thermometer stands out because of its enormous non-contact measurement range that goes from -10˚C to 1500˚C with ±2˚C/1% accuracy and a resolution of 0.1˚C (1˚C when over 1000˚C). When measuring such high surface temperatures, the non-contact capabilities of the thermometer are very useful because there is no need to get close to the surface under test. Such capabilities make the thermometer a relevant and useful instrument across a wide range of sectors.

    The large 50:1 distance-to-spot ratio means that a measurement spot with a 10cm diameter can be targeted from 5m away. A four-point laser helps ensure that this range does not affect accuracy by visibly highlighting the measurement spot. An inbuilt emissivity table also aids accuracy by adjusting for different surface types.

    For instances where emissivity needs to be tested or a more accurate air/liquid temperature measurement needs to be taken, the Testo 835-T2 can also work with a type K thermocouple to perform contact temperature measurement from -50˚C to 1000˚C. Measurements are accurate to ±(0.5˚C + 0.5%) and precise to 0.1˚C. Please note that the thermocouple is sold separately.

    The Testo 835-T2 has a pistol design which makes it easy to handle during tests. This practicality extends to the clear user interface which is operated using the joystick. As well as icons and menus, the clear digital display shows minimum, maximum and average temperatures alongside the time and emissivity level. Up to 200 readings can be saved to the thermometer’s internal memory and then analysed on a PC using the supplied ‘EasyClimate’ software.
