This product has been discontinued and is no longer available. In many cases we can still service and calibrate it. Talk to our team about spares or alternatives.
Atmos is a wall-mounted controlled-atmosphere monitor for rooms where oxygen may fall or CO, CO2 and ethylene may rise. It manages up to three remote gas sensors from a single central unit with adjustable alarm thresholds and 4-20 mA outputs.
KEY BENEFITS
- Dedicated to room monitoring where O2 may decrease or CO/CO2 may increase
- Built-in audible alarm with optional external flash alarm
- From 1 to 3 gas channels per central unit
- Complies with EN 50104 version 2010
- Remote sensors up to 1 km away without signal amplifier

Continuous room monitoring for controlled atmospheres
Atmos is a wall-mounted device designed to protect workers and product wherever gas concentrations can vary and put safety at risk, or wherever ambient storage conditions must be watched continuously.
Remote sensors sample the atmosphere by natural diffusion or convection and can be installed up to 1 km from the central unit without a signal amplifier. The central unit manages alarms with adjustable thresholds and duplicates every measurement to a 4-20 mA output.
Built around three principles of safety, adaptability and control, Atmos supports from one to three gas channels per central unit and complies with EN 50104 (version 2010).
Benefits
- Dedicated to room monitoring where O2 may decrease or CO/CO2 may increase
