Description
The instrument utilizes novel fully calibrated and temperature compensated gas sensors with excellent repeatability, stability, and long lifetime.
Two relays RE1 and RE2 with switching contacts can be used to control alarm sirens, ventilation fans, shut-off valves, or other actuators for each sensor. The detector is equipped with a visual and acoustic alarm for each sensor. 24 VAC or 230 VAC power supply options are available.
