Model 1058-E935 The above digital Gas Monitor/Transmitter is a microprocessor based digital transmitter which, accepts signals from toxic & combustable gas sensors and provides a 4-20mA output. Additional features of the gas monitoring system include RS-485 communication, a digital display and a mechanical as well as a nonintrusive user interface. The gas monitor Transmitter fits inside an industry standard EXP enclosure. Model: killark HKB-BC series, or similiar PVC housings as required by the installation. Calibration on the Gas monitoring system can be performed either via the mechanical switches on the display or by using a magnetic source through the glass dome cover of the enclosure and activating the Hall Effect Switches.   1058-E935 Digital Transmitter Digital display: The digital display on the Gas monitoring system is separated into two displays: a single digit function display and w three digit value display.

Adjacent is an anolog gas monitoring system. Sensors can be set up to detect any number of harmful gases.  Co ,Co2 , anthrax, So2, etc. These units are ideal for underground subway systems, underground parking garages. They can also be intergrated with the exhaust fan system by regulating fan speed . When gas is detected fan speed automatically speeds up to exhaust harmful gas, then slows down saving energy and operating cost

Multiple sensors can be set up to distiguish between different gases. These gas sensor units are very accurate and can be set up to detect ppm gas counts.
