The Rapid RH™ is intended for interior use only. It is imperative that the interior 

application area be protected from weather elements such as rain and snow to 

prevent water intrusion. The Rapid RH™ is not to be used in concrete less than 

28 days old. Follow

It  is  important  to  avoid  condensation  on  the  Rapid  RH™  Smart  Sensor.  If  the 

sensor is colder than the dew point temperature of the environment being tested, 

condensation  can  occur  causing  inaccurate  readings  and  potentially  damaging 

the sensor. To avoid condensation on the sensor allow the probes to stabilize at 

room temperature before removing from the package. This action is especially 

important  if  you  bring  the  Rapid  RH™  Smart  Sensor  from  a  cold  environment 

(such as an unheated area of a vehicle) into a building.
