Description
The Water Activity (ERH Meter) is a high-precision device designed for the accurate measurement of water activity, also known as Equilibrium Relative Humidity (ERH). It meets or exceeds the stringent standards of USP-NF 1112 and serves as a reliable alternative to microbial limit tests for non-sterile pharmaceutical forms, such as APIs, creams, ointments, lotions, and liquids. Equipped with advanced digital sensor technology, this meter provides easy, non-destructive measurements and is supported by internationally certified calibration standards. It requires no maintenance and incurs no recurring costs, making it a cost- effective solution for both laboratory and production site applications, including on-site monitoring. Additionally, the device can generate sorption sotherms, allowing for precise moisture content analysis in various materials.
