Water Activity Meter

Water Activity Measurement, Moisture Meter, Measurement and Monitoring of AW Value

The measurement of water activity or equilibrium relative humidity (ERH) is a key parameter in the quality control of moisture sensitive products or materials. If too much water is available in a product, there is a risk of microbial growth and water migration. Our aw measuring devices are very well suited for water activity measurement in various regulated applications and have a wide range of uses: they are used for water activity analysis in the production or storage of pharmaceutical products, for example. Our aw products are also used for measurement in the food sector, where fast and precise measurement results are a decisive advantage.

  • USB Interface (HC2A-AW-USB)

Overview

The new HC2A-AW comes with new and enhanced electronics, which improves the self-heating property compaired to its predecessor HC2-AW. The HC2A-AW has the Rotronic UART Connector and can be used with the HygroLab. The HC2A-AW-USB Probe has an USB Connector for direct connection to a PC in combination with the HygroSoft Software. The HygroSoft Software with the Water Activity function must be ordered separately.

Rotronic Accessories for Water Activity Measurement

Key Features

  • Various sample holder sizes ensure excellent sample containment.
  • Different container sizes for optimal sample volume.

Overview

The sample holders provide excellent sample containment and optimum temperature stability. The WP-40TH can be attached to a water bath for additional temperature control. The disposable sample containers ensure the optimum sample volume is introduced into the sample holders. They prevent the sample holders from coming into direct contact with the product being tested, thereby preventing soiling or cross contamination. The sample containers also provide a convenient means of collecting and storing samples
