Continuous Monitoring of Gas Output from Gas Mixers or Within Buffer Tanks

Specifically for the continuous monitoring of a gas mix from a pressured source, including from buffer tanks and gas mixers. There are 3 versions available:

Monitor %O2 only – reports %O2 & % Balance.
Monitor %CO2 only – reports %CO2 & % Balance.
Monitor both %O2 + %CO2 – reports %O2 & %CO2 & % Balance

Particularly useful in monitoring the consistency of the gas mix produced by traditional, old technology gas mixers, from which the gas mix fractions can change repeatedly, with changes in the gas input pressures. The test data can be automatically downloaded to Paperless QA software.

Process  The Dansensor® MAP Check 3 Pressure continuously draws a gas sample, controls the pressure of the gas sample and passes it through a Dansensor Zirconium O2 sensor & IR CO2 sensor.

A continuous stream of realtime test results are compared against the target values for that specific mix. Alarms are activated if the test results are out of specification. A current, or voltage signal and 24VDC logic for stop/start can also be sent to stop/start the process. The data can also be exported in realtime via a LAN or RS232 ports.
