| Operating Conditions |
| RH 0 to 90% |
| Communications Interface |
| Analog, The sensor output is amplified by the
Control Electronics to give an output from
the kit equal to: (2.3E + 0.106)V
The output from the sensor
follows the Nernst equation:
Where E = sensor output (V), R = Gas
Constant, T = Electrode temperature (K),
F = Faraday Constant
PO2’’ = Oxygen partial pressure of reference
gas, PO2’ = Oxygen partial pressure of
sample gas |
| Other Chemical Targets |
| O2 |

| Start Up Time (From Cold Start To Sample Ready) |
| 3 to 5 minutes |
| Response Time (Sample Application To Output) |
| Continuous (<30 seconds); <8 secs for a step change from 2ppm(v) to 10ppm(v) O2 |
| Training Required |
| <1 day training |
