CINCINNATI SUB ZERO Temperature Humidity Environmental Test Chambers

Excess moisture is very damaging to a multitude of products especially electronics causing corrosion and oxidation. Low humidity levels can cause brittleness as well as interact with certain to cause high electrostatic discharge (ESD) conditions. Humidity testing allows a manufacturer to see how their product will perform in these conditions. Most manufacturers offer temperature humidity chambers ability to achieve 10% to 98% RH although, similarly to temperature, humidity levels can also be customized.

Even though most temperature humidity chamber manufacturers specify the humidity rang to be 20% to 95%RH, there are limits when testing at lower humidity levels at certain temperatures. For example most standard temperature humidity chambers will be unable to achieve humidity leves of below 45%RH at 20C. Should lower humidity levels be required, a dehumidier package option is available. It uses dessicant dryers and requires compressed air to operate. With this option, a temperature humidity chamber can achieve humidity levels down to 5%.
