I think I'm being very anal about the amount of flushing I do. I doing at least 4-5 flushes and I follow your directions to a tee. I'm getting 9 mv in air but only 40 mv in O2. I've just replaced this cell with another new one and now I'm getting a reading of 48 mv and my other two are reading 54's. I know the other two are correct because I've been keep a log of the readings. I've got the sensor in a box right now ready to ship back so if I need to do try anything else. I did the calibration routine about 4 times and it still would not go above 40mv.

do me a favor for curiosity, measure the 3 cells in air using a voltmeter.. the HH does some rounding (to the nearest mv) so I need to see the actual values at the low end, because 9mv in air should be about 43 in 100%..
