SC-VTS Vapor Test System
The SC-VTS Vapor Test System contains an environmentally responsive
chamber where the sensors are placed for testing. A user-friendly
computer program varies the temperature, humidity, and the
concentration of up to (typically) five different vapors or gases
inside the chamber while recording the output of up to forty
sensors. The system can accommodate most small gas sensors without
modification and test runs are fully automated.
