Water activity tester HTY-AW01-TH

laboratoryfor the food industryfor the pharmaceutical industry

Product overview
The HTY-AW01-TH water activity meter determines sample aw using the mirror condensation method with controlled temperature and humidity. Suitable for quality control and R&D in pharmaceuticals, food, cosmetics and environmental testing to assess microbial risk and shelf life.

Key features

• Mirror condensation method: Traceable to SI units and aligned with USP recommended methods (USP 922, USP 1112).
• High accuracy: Resolution 0.0001 aw and high-precision capability (±0.003 aw) with a maximum allowable error ±0.02 aw.
• Active temperature control: 10–50 °C range with ±0.2 °C accuracy for fast and repeatable measurements (typical test time ≤30 min; with active control measurement time can be reduced to ~4–6 min).
• Data management: 3-level user access, audit trail and 21 CFR Part 11 support; long-term storage (>10 years).
• Low operating cost: Inexpensive consumables and minimal sensor maintenance.
