Description

HP23-AW-A Handheld instrument for measuring water activity. Suitable for connecting 2 probes, equipped with 2 analog inputs 0..1 Volt or 4..20mA, mini USB connection, with remote function and AW-Quick function.

In many situations it can be very useful to measure water activity in production or storage rooms, e.g. inspection of bulk materials to ensure they meet specifications. The HygroPalm 23-AW-A is ideal for measuring water activity in production processes such as random checks of cheese, meat, tobacco, building materials, animal feeds, bakery products, paper, medicines, horticulture, agriculture, etc.

Applications
The HygroPalm HP23-AW-A offers the perfect solution for on-site water activity measurements to confirm product stability and indicate shelf life. The HP23-AW-A is suitable as a mobile laboratory unit. Equal to the HygroLab C1 the HP23-AW-A is perfect as a portable analyzer with two probe inputs for any suitable HC2 probe. The HP23-AW-A can also be used in conjunction with HW4-P-QUICK-Vx.

Features

  • 2 input channels for HC2 station probes or HC2 insertion probes can be connected for measurement of water activity, relative humidity and temperature
  • AW Quick function for fast measurement results (typically 4-5 minutes)
  • Audible alarm to indicate completed measurement
  • Saves up to 10’000 data records with %rh, °C, date and time
  • Battery charging function
