ms1 Set aw

Precise, fast, flexible

A practical, 1'000-times proven precision hand-held measurement instrument for aw / relative humidity and temperature measurements. Thanks to the Novasina electrolyte-Sensor it is well-suited for precise aw measurements in many types of products. The instrument and its sensor are very robust, have excellent long-term stability and are practically hysteresis-free.

The large and clear LC display is very easy to read. The instrument is powered by a 9 V battery powered, but an additional mains power supply is available to support long-term measurements. The sealed measurement probe cell is not temperature-controlled. The measurement temperature can be displayed at any time on the large LCD display. The instrument has an indicated stability value display function. An optional RS 232 interface and supporting software is available for connecting a printer or PC.

The instrument is delivered in a sturdy plastic carrying case with space for various additional accessories. Measurements can be made with the instrument in its case.

Examples of aw measurements with the Set aw:

All forms of baked goods
Meat, sausages and cheese
Dried foodstuffs, fruit concentrates
Cosmetics
Pharmaceuticals, natural medicines
