testo 835-H1 infrared thermometer with humidity measurement
Measuring temperature and humidity on walls, checking air conditioning and ventilation systems, maintaining industrial systems and ensuring quality in production processes: the testo 835-H1 infrared thermometer with humidity measurement is the ideal all-rounder for trade and industry.
What the testo 835-H1 infrared thermometer with humidity measurement does
- Measure surface temperature, relative humidity and check the dew point and surface humidity
- Detect the risk of mold on building materials in good time
- Measure small, movable or difficult to access objects precisely and reliably
Benefit from the latest technology and easy handling
- 4-point laser accurately indicates the measuring range and thus prevents incorrect measurements
- 50:1 optics: you still get first-class results in surface temperature measurement even at long distances (5 m distance = 10 cm measuring spot)
- Adjustable emissivity: many different surfaces can be measured
- Input for temperature sensor: additional contact measurement possible for materials with low emissivity - simply connect an optionally available temperature sensor
- Automatic determination of the emissivity by optionally connectable temperature sensor
- Convenient menu navigation with icons and joystick
- Create measuring locations and save up to 200 measured values
- Define free alarm limit values, audible and visual alarm
- Display of min/max values and illuminated display
