Environment temperature and humidity sensor inside

Unit based on embedded system, 24bit Δ-Σ AD

Traceable reference film calibration

Supports DSM system (DSM, lab data management system) Principles：

The specimen is clamped between the upper and lower chamber, the upper chamber is high humidity side, and the other side of specimen, lower chamber is purged by a stream of dry gas, due to the effect of water concentration gradient at two sides of the specimen, water molecules will permeate through the specimen into the dry gas side, penetrated water molecules will be carried to the relative humidity sensor which generates the proportional signal, so water vapor transmission rate will be obtained by calculating the sensor signal.
