ABC stands for Automatic Balance Cycle which is a technical term for enhancing the accuracy and prolonging the operation of the chill mirror hygrometer. The ABC cycle can be programmed at user’s settable intervals.

3) What are some special considerations when trying to measure a dew point below -40C?

When measuring below -40C, use stainless steel material (tubing, fittings, etc), recommended flow rate is 1-3 SCFH, pump and flow meter should be mounted downstream from the sensor, and minimize the amount of fittings used (source of leaks).

4) Does EdgeTech rent equipment?

Yes, the EdgeTech rental policy is per month and there is also a rent to own program.

5) What are the advantages of using a chill mirror sensor over other technology (secondary measurements)?

9) How do you measure elevated dew points above ambient temperature?

 A) All components that the sample gas contact must be at a higher temperature than the measureable dew point. This includes the sample gas lines.

10) What does a typical sampling system look like?
