ServersCheck Digital Gas Sensors
This sensor is designed for detecting the presence and level of specific gas concentrations in critical facilities. A sensor is assembled and programmed to detect one of the different gas types we support: C2H4, CH2O, CH3SH, CH4, CL2, CLO2, CO, CO2, ETO, H2, H2S, HCL, HCN, HF, NH3, NO, NO2, O2, O3, PH3, SO2, or R134a.
No personal computer is required for the sensor to operate once configured. The sensor measures gas in particles per million (ppm).
Gas Types Detected
The sensor connects to the base unit (BASE-WIRED). The base unit is a standalone device that has its own IP address in your network. On its own it will monitor the sensor and trigger alerts via email, SNMP or optional SMS when needed. There is no software or PC required for the sensors to run.
The sensor digitally measures the levels of following airborne gasses:
