And another thing... I noticed that the Analox O2 meter has an optional sealing cap which screws into the sensor port, and which protects the sensor from O2 exposure when not in use. Supposed to extend the sensor life, I am told. Seeing as how the CO analyzer is built on the same body as the O2 tester, would this plug fit on it also? And is there any benefit to sealing off the sensor on the CO tester when not in use? Woody
