For Use with an Integral or Remote Mounted Fixed Gas Detector

SCA
Single-channel Gas Detector and Control Panel

Single Gas Infrared (CO2) and Electrochemical Sensors

The Model SCA is a single-channel stand-alone fixed gas detector and/or control panel for continuous gas monitoring in industrial and laboratory applications.

This versatile unit can be used in multiple ways – fitted with an integral sensor for safe area use, connected to a remote fixed gas detector for safe area use, fitted with a safety barrier and connected to a remote mounted intrinsically safe gas detector located in a hazardous area, or connected to a remote explosion-proof/flame proof gas detector located in a hazardous area.

It can be configured to detect oxygen, carbon dioxide, and over 150 flammable and toxic gases, and it can operate independently or integrated into the process or plant control system.

Features include three built-in alarm strobes, an alarm horn, a large backlit LCD display, external pushbuttons for easy calibration and maintenance, and an optional internal battery back-up. The enclosure is waterproof and dustproof and includes a lockable door panel.
