Family Description

The ACI Q8 Series of explosion-proof gas detectors are used in applications that require a rugged enclosure that meets Class 1 Division 2 requirements. Each unit comes standard with an integral clock, digital display of concentration, relay status, and peak daily values of the gas being detected. A three-color backlight will flash depending on the level of alarm for operator safety. Setup and calibration are accomplished through non-intrusive magnetic switches that allow programming for all parameters. A remote sensor option is available for toxic and combustible gases and should be used in applications where the main unit can be mounted 3- 6 feet off of the floor with the remote sensor being at the ceiling or floor levels to monitor the gas concentrations. Mounting height and remote sensor location depend on the gas being monitored. Sensor types include electrochemical and catalytic bead sensors to meet the demand and performance requirements for particular industries.
