MV Specs

Does anyone have the tolerances in MV for air and oxygen?

Thanks
Marty

I get about 9 to 12 in air and about 45 to 50 or so in oxygen.

If your cells are linear, the O2 output should be 0.99/0.209 x the mV output in air.

For e.g. Air = 9.0 mV, O2 purity = 98%

O2 mV = 0.98/0.209 x 9.0 mV = 42.20 mV

8 to 12 MV air if its less than 8 replace
40 MV min on O2 if less it will not calibrate

Just had 2 new sensors in package fail calibration, ran at 30mv and 36mv in O2. People at AI Inc are great in cross shipping replacements.
