Analox Sensor Technology has designed a new multi-gas monitor for the food and beverage (F&B) industry, which sniffs out both carbon dioxide (CO2) and oxygen (O2).

Based on the UK-based business’s existing Ax60 CO2 detector, the new, wall-mountable device incorporates a modular O2 sensor, providing an early warning of both O2 depletion and O2 enrichment as well.

The Ax60+ can use up to four alarms per sensor with a maximum of eight alarms per system. Each alarm unit has an audible sounder and a high-intensity LED strobe light, with the alarm set-points individually configurable by the operator.

Its CO2 sensor is set to trigger a low-level alarm at 1.5% CO2, an evacuation alarm at 3% CO2 and a time-weighted average alarm of 0.5% CO2 measured over eight hours. Its O2 sensor is set to trigger low-going alarms at both 19.5% and 18% and a high-going alarm at 23%. All alarms are set initially by default.

Other key features include a multi-point, multi-gas, distributed monitoring system, four-channel flexibility for multiple sensor combinations, a central display unit for remote operation and control, and built-in software for operation and maintenance tasks.

In addition, the CO2 and O2 sensors are interchangeable and can be fully integrated as part of a multi-point, multi-gas detection and alarm system.
