Protection Filters

Company: Novasina

Certain volatile compounds as glycerin, alcohol and others will temporarily or permanently harm the Novasina sensor and/or will adulterate the measurement result. As a consequence, it might happen that the user thinks, the product is safe as water activity is below the limit, but as value is spoiled by volatiles, the real water activity value is higher. To avoid such uncomfortable situations and to get the real water activity value on display, chemical protection filters have to be used.
