The EC-Gold is a toxic gas and oxygen transmitter using electrochemical sensors for ambient air monitoring in commercial, residential, and light industrial applications. It features a protective aluminum housing with NEMA/Type 1 (IP40) rating, measures 197mm x 76mm x 76mm, and is designed for surface mounting. The unit operates on 14-24 VDC, provides 4-20 mA and RS-485 Modbus outputs, and supports calibration via an external push button without opening the enclosure. It is approved to CSA and UL standards, functions in temperatures from -20°C to +50°C, and handles humidity levels of 5-90% non-condensing. Sensor options include CO, NO₂, NH₃, H₂S, Cl₂, and O₂, with factory defaults specified for each.
The EC-Gold gas transmitter is part of the Arjay series of gas
detection instruments. This employs electro-
chemical sensors to target toxic gas or oxygen
concentrations in ambient air. The unique design
and flexible interface allows this transmitter to
be used with any of the Arjay controllers or
directly with your own site automation or
control system.
• multiple outputs and communications
• robust metal housing
• wide variety of sensor options
The on-board sensor continuously monitors the
ambient air by natural diffusion. The sensor
responds proportionally to the gas concentration
in the air. A signal is sent to the control panel or
system for ventilation or alarms.
