New Analyser Measures CO2 at High Pressures

A new sophisticated new gas analyser that measures carbon dioxide (CO₂) under pressure extremes has been developed by Sensor Electronics (USA).
CO₂ dilutes explosive concentrations of ethylene oxide (EtO) in, for example, medical equipment sterilizaers and research laboratories. (EtO is both toxic and extremely flammable.)
Because of intermolecular energy transfer between EtO and CO₂ (and nitrogen, oxygen, H₂O) under pressures, accurate CO₂ measurement is virtually impossible.
Unlike erratic readings with conventional CO₂ detectors, this new analyzer ignores the transient extremes to give precise CO₂ measurements through the cycle.
The analyzer uses twin source–to-sensor pulsating infrared beams, thus eliminating mirrors/lenses/splitters, and problems with dust, dirt, condensation, contamination and misalignment. It also shrugs off temperature and humidity extremes.
Self-correcting circuitry means the analyzer can work for years with-out fussy adjustment or recalibration.
The analyser even keeps a watchful eye on itself, flashing immediate warning of any internal problems, then spelling out what`s wrong where.
The unit can link up with printers, plotters, loggers, computers to make a permanent record of fast-changing CO₂ values.
