The GasChek 4 is a microprocessor based fixed gas detection system designed to accept the input from one to four remotely located oxygen, combustible or toxic detector assemblies. BiosystemsGasChek 4 Multi Channel Fixed gas Detection SystemGasChek 4 systems are designed to provide continuous round-the-clock monitoring for a variety of common atmospheric hazards including oxygen deficiency and/or enrichment, combustible gases and vapors, and specific toxic contaminants such as carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2), chlorine (Cl2), and nitrogen dioxide (NO2). 

The system is designed for easy expansion by means of plug-in sensor modules. Remote detector assemblies are available in non-explosion proof or explosion proof versions. Both types of detector housing include digital readouts and switches which allow for single person, non-intrusive calibration adjustment. 

All GasChek 4 systems include built in digital readouts at both the controller and remote detector. Other standard features include two independently adjustable alarm setpoints per channel, built in audible alarm, bright LED alarm light indicators and relay contacts for fault, low and high alarm conditions; common and channel specific 1-5 Volt or 4-20 mA user configurable analog outputs, and built-in 12V sealed lead acid battery backup power supply.
