Tested |
Disposed |
I (Sara Knox) tested the probe in the lab to try to figure out what was wrong with it. It still maxed out at 5000 mV and the lights on the circuit board were flashing red and green. I took it out of the teflon tubing to inspect the probe for water damage - sure enough it was all corroded. I think its dead Jim. |

Calibration |
Lab none |
Trueppm = Probeppm*0.9873 + 114.4; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 436ppm, 3056ppm, and 10000ppm. Ta=25.9C, P=101.4kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Sara. |
