PORTABLE SAMPLE DRAW TOXIC GAS MONITOR
Dual channel compatibility allows the R-3557-P to monitor one or two low cost, disposable Delrin sensors that can be easily replaced by the user. The “ECHEM” channel supports any of the 20+ toxic sensors, and the “BRIDGE” channel accepts inputs from SmartIR infrared LEL and CO2 sensors as well as the Photoionization Dectector (PID) for monitoring Volatile Organic Compounds (VOCs).
The highly visible backlit display shows calibrated engineering values, bargraph data, 30-minute trend and setup information. An internal real-tiime clock time-stamps calibration and alarm events for later review. Front panel LEDs continuously indicate alarms.
