$ 476.00
  • Measures temperature / moisture / dew point
  • Calculates surface moisture content
  • Easy to follow menu guide, memory of up to 200 readings, data analysis with free to download software
  • 4-point laser and 50:1 optics for precise measurements, even over long distances
  • Non-contact temperature and moisture measurements using only one device. The testo 835-H1 infrared thermometer measures the air temperature, and also has an intergrated moisture sensor for measuring moisture.

    For high temperature applications, see the testo 835-T2 (0560-8352)
    Perform temperature monitoring and checks on air conditioning and ventilation systems, inspect industrial systems and rotating equipment, and ensure constantly high levels of quality in production processes. The testo 835 is ideal for a wide range of industrial and commercial applications.

    What the testo 835-H1 infrared thermometer and moisture meter can do

    • Measure surface temperature / RH and check dew point / surface moisture
    • Timely detection of mold in buildings
    • Carry out quick and safe measurements on small / moving / hard to reach objects

    State of the art technology and easy handling

    • 4-point laser shows exact measuring zone, effectively preventing incorrect measurements
    • 50:1 optics for excellent surface temperature measurements, even over greater distances (distance 16 ft  = 4 in. measurement spot)
    • Adjustable degree of emission (for measuring a wide variety of different surfaces)
    • Connectivity for temperature sensors for additional contact measurements (for materials with low degrees of emission). Simply connect optional temperature sensor
    • Easy to use, easy to follow menu guide, thanks to icons and joystick
    • Generate measuring points and save up to 200 measurements
    • Define individual alarm thresholds, acoustic and optical alarm
    • Display min/max values
    • Backlit display

    Location of thermal bridges and mold or corrosion formation

    With the testo 835-H1, you can identify thermal bridges (places on walls, floors and ceilings where there is a greater outflow of heat) for early detection or identification of structural defects, energy loss and places where there is a risk of mold / moisture formation. the long range 50-1 optics provide spot accuracy for smaller mechanical components
    Advantages of the testo 835-H1:
    • Fast detection of thermal bridges by scanning the walls, even at great distances
    • Measurement of the dewpoint, dewpoint distance and aw value (surface moisture) to assess conditions of the room and wall
    • Saving the data for documentation and comparison with previous measurements in order to evaluate corrective measures
