Calibrating the Model S4000CH Combustible Gas Detector with a remotely installed sensor is now easier than ever with the new Automatic Remote Gas Calibrator (ARGC; photo). The ARGC, which consists of a Remote Gas Calibrator and a solenoid valve, blocks ambient air and redirects the calibration gas to the catalytic bead sensor for calibration or testing sensor accuracy. The instrument can calibrate gases at wind velocities as high as 50 mph and maximum temperatures of 75°C. The S4000CH is a hydrocarbon gas detector suitable for use in SIL 3 applications. — General Monitors, Lake Forest, Calif.
