Vibration/Shock; Meets requirements of BS EN 60068-2-6:1996 (IEC 68-2-6), BS EN 60068-2-27:1993 (IEC 68-2-27), IEC 68-2-34, BS EN 150 80601-2-12_2011, ISO 80601-2-58
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
Sample Introduction
Vapor/Gas
