Humidity Testing Capabilities at Keystone Compliance
Keystone Compliance offers temperature and temperature humidity testing in chambers ranging from small bench top to large drive-in systems. Our walk in chambers were designed to accommodate large equipment or packages. Currently, our largest chamber has dimensions of 12’x9’x10′ which is a volume of 1,080 cubic feet. Our walk in chambers allow Keystone Compliance to be capable of moving, installing, and testing multiple rack assemblies. We also have the capabilities of building extensions off of the chambers to test even larger items. Keystone Compliance also operates a large walk-in chamber that is specially equipped with twin 30 hp compressors and is capable of temperature transition rates exceeding 15 degrees Celsius per minute. All of Keystone Compliance test chambers operate with state of the art digital temperature controllers. Every chamber is equipped with high and low temperature safety devices.
Humidity Testing Lab Equipment at Keystone Compliance
Keystone Compliance operates state of the art temperature and temperature humidity test chambers. Our investment into our brand new drive-in chamber is a reflection of our years of testing experience. We realize that temperature and temperature/humidity tests are the longest running tests in your testing program, and we understand the importance of reliability of environmental chambers.
Our chambers have a wide range of temperature capabilities. Our reach-in chambers range from -73C to +180C. The walk-in chamber range from -73C to +180C. We also have lab ovens that can reach up to 2,500C, and create custom test setups that can go as cold as -196C. These temperature ranges allow us to achieve humidity ranges from 10% to 98%.
Humidity Testing Overview
Humidity testing, per MIL-STD 810 Method 507, introduces products to increasing levels of relative humidity to determine a product’s ability to operate in certain environments. Humidity testing will signal any design flaws that might lead to common humidity issues such as electrical failures, swelling of materials, change in surface condition, deterioration of optical equipment, corrosion, oxidation and accelerated wear on moving pieces. Humidity testing can be completed by using the direct condensation and indirect effect.
Direct condensation is the formation of water droplets on a device that can cause direct damage to susceptible components. Indirect effect can vary in form but generally involves moisture reaching sensitive components that cannot operate correctly in a moisture-filled environment.
