WET-SOCK METHOD

This method can be used to obtain relative humidity, dry/wet bulb and dew point mea-

surements using two standard TMX2G temperature probes and channels A and B. There

are two options for Step 4. Both options provide accurate readings and are merely a

method of user preference.

Step 1: Connect a TMX2G probe to Channel A

and another to Channel B.

Step 2: Press the RH key and then the MIN

key to display the minimum value

of the RH.

Step 3: Slip a supplied 2" cotton sock* over the

end of the TMX2G probe connected to

Channel B and wet it with distilled

water.

Step 4 (Option 1): Grip both probes approximately 18" from the ends in one hand.

Proceed to swing the probes in a circular motion through the air until the

display reading stabilizes. At that point you can stop swinging the probes.

Step 4 (Option 2): Place both probes in front of an air stream from air handler or

second) over the wet sock ensuring that no radiant heat flows into the probe

such as direct sunlight or heat from machinery. The correct measurement is

obtained when the display stabilizes.

Step 5: Press the CLR key to erase the readings during the stabilization period and

display the current values. Pressing the RH,DB,WB or DP keys will display the

current value of the relative humidity, dry bulb, wet bulb, or dew point

temperatures.
