O2 Sensor for PCA 20 Analyzers

This replacement sensor detects oxygen levels from 0 to 20.9 percent with a resolution of 0.1 percent vol. It is designed specifically for use with Bacharach PCA 20 combustion analyzers. The unit arrives new and ready for immediate installation in compatible instruments.

For Technicians Maintaining PCA 20 Units

Combustion analysts who need to restore O2 measurement capability on a PCA 20 will find this the correct part. It is not suitable for technicians using other analyzer brands or different Bacharach models that require a different sensor interface.

Measurement Range and Response Time

The sensor covers 0 to 20.9 percent oxygen concentration and delivers a T90 response time of 20 seconds. Operating limits are 32 to 104 degrees Fahrenheit, so the analyzer must be used within this temperature window for accurate readings.

Questions about this item

Does the 24-0788 sensor generate heat or noise when running continuously in a PCA 20?

The sensor has no moving parts and draws only micro-power from the detector, so it adds no audible noise or measurable heat during all-day operation.

What must I already own for the 24-0788 to function?

You need a Bacharach PCA 20 gas detector; the sensor plugs directly into that instrument and requires no separate power supply or controller.

Will the 24-0788 work with an older PCA 20 that has been in service for several years?

Yes, the sensor is designed as a direct replacement for the original O₂ cell in any PCA 20, matching the 0 to 20.9 % range and 20-second T90 response.
