6.  Alternately, insert the RH sensor into the sleeve immediately after setting the 

sleeve. Readings can then be taken as soon as the hole has acclimated.  

 

CAUTION  - ABOUT THE RH/T SENSOR  

 

Continued exposure to high temperature and humidity, chemical vapors, and any other 

corrosive environment will accelerate inevitable sensor aging, loss of calibration, and 

possible permanent damage. The sensor always must be stored inside the pouch in 

which it was received and in a clean, dry place when not in use. It is best to keep the 

meter and sensor in the carrying case. We recommend checking calibration periodically 

with either a “reference sensor” which is kept strictly for this purpose, or a salt solution. 

Both are available from Delmhorst or your supplier. 

  

 
 

CARE OF YOUR METER 

 

 

Store your meter in a clean, dry place.  The protective carrying case provided is an 

ideal storage place when the meter is not in use.  If the meter has been left in a hot 

or cold environment overnight or for an extended period,  allow the meter to 

acclimate to the temperature conditions in which it will be used for minimum 1-2 

hours, or as long as possible. 

 

 

Clean the meter with any biodegradable cleaner.  Use the cleaner sparingly and on 

external parts only.  Keep cleaner out of the sensor input connector. 

 

After each use, place the RH/T-S1 sensor in the static-free bag it was shipped in and 

keep in the carrying case or a clean, dry environment. 

 

 

Remove the battery if the meter will not to be used for one month or longer.
