Single Channel Gas Detector Control Panels
Selection of Enclosure Types and Sizes
Our PST owned brand, Status Scientific Controls have manufactured a range of high quality single and multi-channel gas detector control panels which are used throughout the world in various different industries.
Single Channel Control Panels
The MCU1 is a single-channel, wall-mount, monitoring and control unit for use in a safe area where there is no risk of the presence of potentially explosive gases.
- Integral sensor options comprise CO2 (Infrared), oxygen, or a wide range of toxic sensors.
- Can be used with the full range of Status Scientific Controls fixed gas detector heads – certified types require use of an integral safety barrier.
- Green, amber and red flashing indicators in lens section.
- Alphanumeric display with backlight.
- Full calibration menu via external push buttons.
