Accuracy
Moisture reading (parts per million by volume)

±1% of reading or ±2 ppmv, whichever is greater; for > 1000 ppmv, ±5% of reading

For CO2 applications:
±3% of reading or ±5 ppmv

For H2 recycle applications: ±1% of reading or ±2 ppmv (for up to ±5% H2 and ±1% C2H6 variation from nominal calibration composition)

(Background conditions for individual instrument calibrated accuracy provided in Certificate of Conformance. Accuracy of other parameters derived from ppmv.)

Repeatability ±0.2 ppmv or ±0.1%, whichever is greater; For CO2 applications: ±1.0 ppmv or ±0.5%, whichever is greater
Calibration Certification NIST or equivalent NMI traceable certification
Calibration Options Nitrogen, standard natural gas and 3 customizable calibration curves
Response Time
Response Time Optical system <2 seconds
System Response The system response is dependent on the length of sample tubing, sample system components, flow rate and pressure, as well as the change in moisture concentration.
