  • The practical infrared thermometer testo 835-T1 offers maximum safety and precision when measuring the temperature of smaller objects from a medium distance.
    Get started in the field of intelligent infrared measuring technology. The practical infrared thermometer testo 835-T1 offers maximum safety and precision when measuring the temperature of smaller objects from a medium distance, e.g. monitoring wall temperature, troubleshooting in heating and air conditioning systems, or the quality control of industrially manufactured products.
     
    • 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-T1 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-T1 infrared thermometer to suit your needs.
     

    For easy analysis and easy use
