Q8 SERIES

Explosion Proof Gas Sensor

The new Q8 Series of Explosion Proof Gas Detectors are used for applications that require a more rugged
enclosure and meet Class 1 Division 1 requirements. Each unit comes standard with a digital display of
concentration, relay status, STEL, TWA and peak daily value of the gas detected. A three color backlight
will flash depending on the level of alarm for operator safety. Set up and calibration is accomplished
through non-intrusive hardware that allows programming of all parameters. Remote sensors are available
for all types of gases. Sensor types include electrochemical, catalytic bead, and infrared to meet the
demands and performance standards of particular industries. Communication is accomplished through
Optomux and Modbus RS 485, 4-20mA, and three user programmable relay contacts. Remote explosion
proof sensing is available for all types of sensing technologies.
