Volatile Filters

Description

Novasina has specially designed these filters to be installed in your water activity meter’s measurement chamber to provide protection against chemical contamination and degradation of the resistive electrolytic sensor element. The inner part of the sensor consists of a liquid, and therefore volatiles which dissolve and dissociate are extremely dangerous and harm the sensor in a very short time frame. 

As volatiles are absorbed by the filter it will become saturated and will need to be repalced. We recommend using the following rule of thumb as a changing interval: 

• If you do less or equal to 10 measurements a week, change filter every 6-12 months
• If you do more than 10 measurements a week, change filter every 3-6 months
• If the instrument is in use day and night, change filter every 2 months

To ensure you are using the correct filter for your samples, review the table below:
