The TS282EC-S employ an electrochemical cell for the Carbon Monoxide (CO) detection in the environment offering a standard three-wire linear 4-20mA output signal. The instruments are housed in a self-extinguishing thermoplastic case. The TS282EC-S is rated to IP65. These devices are employed in gas monitoring systems for laboratories, factories, car parks, etc. They may be connected to microprocessor based  central units model BS-340/308/316 and BS-370 or to any 4-20mA input device complete with power supply unit.
