Licor at psi, Licor 750 at 99 Tdewspan=12
CO2 zero 0.957 -> 0.9182 Offset: 0ppm
CO2 span 1.0075 -> 1.0 Offset: 0ppm
H2O zero 0.7337 -> 0.8187 Offset: 0ppm
H2O span 1.0078 -> 1.0094 Offset: 0ppm
Notes: Factory calibration at Licor after replacement of chopper, detector and source. Unknown ambient conditions and offsets. This sensor was sent to Licor because its signal was noisy. Its parts are almost 20 years old so I asked to have it renovated. Licor said, "Inspected the unit and found it in operational condition. Replaced the chopper motor, the detector and the light source. Subjected the unit to environmental tests and calibration." Should be nearly as good as new.
