[PSUBS-MAILIST] FW: O2 and CO2 sensors

[Alan James via Personal_Submersibles]

Thanks Jon,Can you remember what ABS or DNV-GL require re range of monitoring? I am tempted to buy 2 of the $26- infrared units on Ali & set them up & compare their outputs.The specs seem good & waterproof.These are 0-5000ppm.Regards Alan
