Vacuum differential pressure method
Built in embedded system with 24bit Δ-Σ AD, remote maintenance and upgrade
One-Click start a test and test automatically stop, no any manual operation is required during the process until the end of the test
Do NOT need to preset any test parameters before a test, zero operation experience requirements, proprietary technology
3 specimens test simultaneously and independently
According to the test state, the vacuum pump starts and stops automatically, do NOT need manual operation
Computer control, multiple test modes: Increment, proportional and intelligent
The temperatures of chambers which hollow inside and with circulating water are stable, high precision and wide range, 3 chambers with independent temperature sensors to monitor
Test under various RH conditions with Humidity generator (optional)
Built in environment temperature and humidity sensor
Permeability coefficient ,solubility coefficient and diffusion coefficient test
Various curves display: chambers temperature, test pressure, transmission rates, etc
Traceable reference film calibration
Supports DSM system (DSM, lab data management system)
