Key Features

  • Relative humidity, absolute humidity, dew point, equilibrium moisture content, aw-value
  • Long stable humidity sensor
  • Easy data storage at the portable moisture meter
  • Analysis on the PC and printer available
  • Optimal documentation of your quality
  • Online-function, Hold function, manual data memory
  • Automatic datalog for up to 10,000 logs with measuring point report
  • The meter comes with a carry case and all relevant consumables required. It also comes with calibration certificates and a calibration control kit.

Reliable water activity meter for use on-the-go. 

Suitable for measuring materials like butter, fruit mix, spices, granulate, mushrooms, flour, biscuits or sausage as well as all other food types requiring a check of the water activity value.

The Humimeter RH2 is suited for measuring special material, e.g. plastic granulate or for climatic and environmental applications.

Not suited for juices (syrup), acidic food like vinegar or food and beverages containing alcohol.

Optionally, the humimeter RH2 can be delivered with USB interface for connecting the device to a PC. The included LogMemorizer software can import the measuring values from the device to the PC, additional information can be added, and the data can be archived, exported and processed.
