Description
The PureAire Universal Disilane (Si2H6) Gas Detector is a fixed gas monitoring system designed for continuous detection of disilane in semiconductor manufacturing, cleanrooms, specialty-gas systems, research facilities, and other applications where Si2H6 may be present.
This configuration monitors disilane from 0–15 ppm using PureAire's renewable electrochemical sensor technology. The Universal Gas Detector combines a dedicated gas sensor with a smart transmitter/controller for continuous, real-time monitoring.
The monitor features a local digital display, built-in audible alarm, visual alarm indicators, two adjustable alarm relays, and an active 4–20 mA output for integration with PLCs, building automation systems, ventilation systems, remote alarms, and other facility safety equipment.
PureAire's Universal platform uses a renewable electrochemical sensor cell designed for long-term service and maintainability. Sensor calibration information is stored with the sensor cell to support ongoing maintenance of the monitoring system.
