    Ideal for use in the glass, ceramics or the metal industry: the testo 835-T2 high temperature infrared thermometer is the ideal professional tool for a wide variety of thermal applications in the high temperature range. The testo 835-T2 has an extremely wide temperature range which allows you to carry out thermal measurements up to 1 500 °C - and all from a safe distance. It doesn’t matter whether the objects are small, hard to reach, moving or very hot. Thanks to the leading-edge technology tucked away inside, the testo 835-T2 allows you to measure the temperature in all four cases quickly and safely.
    • The 4-point laser clearly indicates the measuring area and prevents incorrect measurements
    • The 50:1 optics allow you to carry out measurements from a long distance and still obtain excellent results (distance 5 m = 10 cm measuring spot)
    • The integrated degree of emission table enables you to select the correct degree of emission of the measured surface
    • The backlit display allows you to use your infrared thermometer in all lighting conditions
    The testo 835-T2 also allows you to carry out contact temperature measurements. The thermometer is equipped with a connecting point for a wide range of optional temperature sensors. The temperature sensor can also be used to automatically measure the degree of emission of a particular surface. This makes it easier to carry out subsequent infrared measurements.
    There is also a wide range of optional accessories - including a tripod and a robust carry case – that allow you to customize your testo 835-T2 infrared thermometer to suit your needs.

    For easy analysis and easy use

    The testo 835-T2 comes with an easy-to-follow menu, self-explanatory icons and a user-friendly joystick. Your infrared thermometer can be used to create different measuring sites or save up to 200 readings while additional features including min/max values, adjustable thresholds and visual and acoustic alarms which are triggered when thresholds have been exceeded make work more efficient and life easier. The free-to-download software provides you with a quick and convenient means of analyzing your measuring data.
