The Testo 835-H1 is a compact infrared thermometer and moisture meter that can be used to measure both surface temperature and relative humidity. Use its unique, patented infrared surface moisture measurement feature to detect the risk of mould in building fabrics early enough, measure humidity in your environment or check the dew point distance.

The infrared thermometer offers maximum safety and precision when measuring the temperature of smaller objects from a reasonable distance.

Integrated moisture sensor - the Testo 835-H1 is one of the few infrared thermometers on the market that has an integrated moisture sensor. This allows you to measure both surface temperature and relative humidity with one device.
Patented surface moisture measurement - uses a patented infrared method to measure surface moisture. This method is more accurate than traditional methods, such as pin probes.
Laser targeting - has a laser targeting system that helps you to accurately target the area you want to measure.
Data logging - can store up to 200 data points, which can be downloaded to a computer for analysis.
No measurement errors, thanks to focused 50:1 optics (5 m distance = 10 cm measurement spot)
Convenient menu guidance with icons and joystick

The Testo 835-H1 is a versatile tool that can be used in a variety of applications, including:
Building inspections - to identify potential moisture problems in buildings.
HVAC inspections - to check the temperature and humidity of air conditioning and heating systems.
Food safety inspections - to check the temperature of food products to ensure that they are safe to eat.
Industrial applications - to measure the temperature and humidity of a variety of industrial processes.
