Water Activity Meters

Water activity meters measure the water vapour pressure (Aw) generated by the non-chemically bound water in foods and products. This is essential in the quality control of moisture-sensitive materials. Incorrect water vapour pressure levels affect cohesion, storage, pourability of powders, tablet stability, and the adherence of coatings.

Water Activity Probe | HC2-AW
R42,915.00 ex vat
Water Activity Probe - Overview

This digital probe enables quick and easy measurement of water activity. The aw measurement head was developed for use in combination with the HygroLab. It can be calibrated via the HygroLabC1 or the HW5 PC software. The sample holder size is reduced to a minimum, thereby making it possible for humidity equilibrium to be reached quickly for all products being tested, while the metal housing ensures high-temperature stability. All critical surfaces are made of chrome steel for minimal soiling. Water activity specifies the relationship between the water vapour pressure of a product and the saturation pressure of pure water at the same temperature. It is stated in “aw” in the range 0…1 aw and is an important indicator of product quality in the industrial production of plastics and is also very important in the food, tobacco, pharmaceutical and cosmetics industries.

Water Activity Probe - Features
- Measurement range: 0…1 aw (0…100 %rh), -40…85 °C
- UART interface for direct connection to a PC
- Adjusted at 23 °C and 10, 35, 80 %rh
- On/Off switch

Water Activity Meter | AWTherm
R25,975.00 ex vat
Water Activity Meter - Overview

With AwTherm offers a professional, high-end laboratory unit for temperature-stabilised measurement of water activity in the foodstuffs, cosmetics, or pharmaceutical industries. The wide control range permits measurements to be integrated directly into the tempered manufacturing or storage process. Water-activity measurement reacts very sensitively to variances in temperature. Stabilising the temperature prevents imprecise results due to external temperature influences. A further advantage of AwTherm is that the measuring head is removable, which means that the probe can be temperature-calibrated or adjusted to give high precision. It is clear and simple to operate. No laboratory should be without the device. To be used in conjunction with the ROTRONIC HW4 software.

Water Activity Meter - Features
- ROTRONIC HYGROMER® IN-1
- Highest precision through exact stabilisation of temperature
