Controlling High Humidity

When the chamber is controlling humidity above 80%RH, there is a limit on how high the humidity inside the

chamber can climb. This limit mostly depends on the temperature inside the chamber. Approximate

maximum humidity limits vs. chamber temperature are shown in Figure 4.

When operating the chamber below 70°F, some condensation inside the chamber is possible when the

humidity inside the chamber is above 80%RH. As the chamber tries to increase humidity, it pumps warm

vapor into the chamber. At the same time, it tries to control the temperature, causing the temperature

control fins to cool and fall below the dew point. This causes condensation on the fins. Condensation will

not harm the chamber, but will prevent humidity increasing above the limits shown in Figure 4.. Any

condensation can be wiped off with a paper towel.

Make sure not to touch the sensor assembly at the top of the chamber when wiping off condensation.

The H300 unit uses the Watlow EZ-ZONE PM controllers. The controller User's Manual has been provided

with the H300 chamber. In general you should not need to reference this manual, unless you are setting up

a profile.

To change the temperature controller units follow the procedure below:
