testo 835-H1 - Infrared thermometer plus moisture measuring

Order-Nr.  0560 8353

  • Measure temperature, moisture and dew point with only one device

  • Calculate the surface moisture content

  • Easy and comfortable to use: easy-to-follow menu guide, can save up to 200 readings, data analysis with free-to-download software

  • Four-Point-Laser and 50:1 Optics for precise measurements even over long distances

Non-contact temperature and moisture measurements – with only one device. The testo 835-H1 infrared thermometer not only measures the temperature but has an intergrated moisture sensor that allows you to measure moisture too.


Details

Product Description
