H300 Temperature Humidity Chamber

 

 

Page 8 

 

The 

CONT

 switch allows you to turn off both temperature and humidity control to the chamber without 

changing the target set point of either controller.  Both controllers and the chamber will still be On, but no 
power will be supplied to the temperature and humidity control units inside the chamber.  This switch is 
useful when you need to open the chamber door. 

 

Figure 3:  Chamber Controls 

Chamber Door 

The chamber door needs to be sealed for the chamber to maintain proper humidity and temperature.  
Tighten the three door nuts until the white rubber gaskets start to compress.  Do not overtighten the nuts.  
It is unnecessary and will decrease the life of the door rubber gaskets. 

Humidity Control 

The water in the water reservoir inside the H300 is heated by an internal heater.  Depending on the amount 
of water in the reservoir, it may take as much as 30 minutes for the water to reach its target temperature.  
The H300 chamber can be used before the temperature reaches its target in most cases.  However, when 
trying to achieve high humidity (above 75%RH) at high temperatures (above 90°F, 32°C), you may have to 
wait for the water in the reservoir to heat up. 

Note that the water in the reservoir will warm up whenever the H300 is ON, even if the CONT switch is 
turned to OFF.
