Accuracy .............................................................1 % of range or 5 % of reading, whichever is greater
Resolution ...........................................................0.1 ml/min
Compatibility........................................................Air, N2, O2, CO2, H2, and He
Units of measure .................................................ml/min (or SCCM - Standard Cubic Centimeters per Minute)
Relative Humidity
DPM4 Model 2G or 2H
An integrated sensor in the Tester determines relative humidity measurements.
Operating range ..................................................12 to 95 % RH
Accuracy .............................................................3.5 % of reading ±2 % RH @ 25 °C for RH between 12 % and 95 % RH
Resolution ...........................................................1 % RH
Gas compatibility.................................................Air
Units of measure .................................................% RH
