UNCERTAINTY 

Relative Humidity: 5 to 98 %RH, 10 to 100 L/min 0.17% * R + 0.016

Example 1: If the %RH reading is 50 %RH, the uncertainty would then be: 0.17% * 50 + 0.016 = 0.101 

Example 2: If the %RH reading is 10 %RH, the uncertainty would then be: 0.17% * 10 + 0.016 = 0.033 

Dew Point: –27 to + 70 °C Dew Point (Ps <= 140 psiA), 10 to 100 L/min 0.03 °C

Dew Point: –35 to –27 °C Dew Point (Ps > 140 psiA), 10 to 100 L/min 0.05 °C
