Moisture & Rain Test Chamber

Designed to simulate a soaking, rainy environment, Thermotron’s Moisture Test Chambers are built with the water-tightness of sealed components such as head lamps, tail lights, and wiring harnesses making them ideal for conducting a water spray test.


The Rain Test Chamber features a self-contained water recirculation system that eliminates the cost and inconvenience of plumbing in a facility water supply. Water is injected into the test enclosure through specifically-sized nozzles. Flow meters with adjustment valves supply the water spray at specified flow parameters. A rotating test platform can be incorporated in the Water Spray Test Chamber to promote even moisture distribution over the surface of the products under test.


Moisture Test Chambers are available in both top and front-opening configurations. Thermotron has the engineering design capabilities and experience to customize rain test chambers to meet special configurations or performance specifications.


Rain Test Chambers provide the appropriate water coverage as required by the Japanese Industrial Standards (JIS) D 0203 as well as the Society of Automotive Engineers (SAE) standard J575, Paragraph 4.2.3.
