Applications include HVAC/R, agriculture, food and beverage, healthcare and laboratories, process industries, where potentially toxic and combustible gases can accumulate.
The instrument integrates electrochemical, semiconductor, NDIR, and other sensing technologies.
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
Three SPDT relays (2 for alarms, 1 for fault) are provided for remote signaling or concentration control, as well as for fault indication.
Four LEDs and a buzzer provide visual and audible alarms.
Three M20 cable glands, duplicated terminals, and side “ears” allow quick mounting and installation.
Optional WiFi allows calibration and configuration via smartphone, tablet, or PC (no extra apps required).
Possibility of pre-calibrated and easy replaceable Smart Sensors - hot-swappable via M12 connectors, fully interchangeable across gases and with built-in calibration calendar.
