Water activity meter 4TE
Measures water activity (aw) in 5 minutes or less (average reading time: 2.5 minutes) to within ± 0.003 aw. These instruments are the fastest and most accurate available on the market. They can be used for a number of applications: laboratory quality measurements, enterprise processors, storage facilities and others. Internal temperature control allows you to set the measuring temperature between 15 and 50 ° C and use the instrument anywhere - even outside the quality control laboratory. The secret to the 4TE's speed and accuracy is its unique cooled dew point mirror. The dew point sensor is a basic measure of water activity. Unlike other water activity sensors, the dew point sensor actually measures water activity (Aw), not some secondary parameter simply correlated with water activity (Aw). This makes the 4TE extremely accurate, so you can have complete confidence in the sample readings.
One-minute instrument for measuring water activity
It usually takes a long time to measure water activity. The sample must reach equilibrium with the air in the space before it can be read. Depending on the sample, this may take 2-5 minutes - even longer for coated products, high fat products or volatile compounds. Using predictable artificial intelligence, this instrument provides readings of water activity and moisture content per sample per minute, even when measuring volatile compounds. Quickly test as many samples as you need to establish a reliable test protocol and accurately determine water activity.
Vapor sorption analyzer
The innovative design of this instrument uses a fast water activity sensor combined with a very precise scale to dynamically create isothermal graphs. It passes humidified air onto the samples and measures both the weight and the activity of the water. It then creates sorption and desorption isotherm curves with hundreds of points instead of just five or six. And only for a few days (approximately 48 hours), instead of a few months.
