Item # A/CO-R

The ACI/CO Series is a microprocessor based transmitter. It uses an Electrochemical gas sensor to detect a variety of gases. Typical applications are enclosed parking facilities, refrigeration rooms and oxygen storage rooms. QEL engineers, through extensive research and development, have designed the M5 to be an industry leader in performance and application. The M5 offers good value. Standard features within the M5 can only be found as expensive options in other manufacturers’ product. A digital display (LCD), push-button programming and on-board meter jacks are all standard. The transmitter provides an analog output of 4-20 mA DC or 2-10 VDC, linear to the measured gas range, for transmission to the Building Automation System (BAS) or controller supplied by others. The signal is fully user assignable over the gas range and can be configured for rising of falling gas concentration. In addition, the RS-485 communications is built in.
