Would you like to test the water activity measurement without using large amounts of funds? Or do you not need a meticulously accurate and reproducible measurement for your product? The LabStart-aw is exactly the right instrument in this situation. Or even if the demands on accuracy and reproducibility are rather low.
Although the device is designed as a "starter", proven Novasina technology can be found inside, especially the resistive-electrolytic sensor.
