Environmental Testing

The CapabilityBenchmaster

Tenney's Benchmaster temperature and humidity test chambers can simulate a wide range of temperature and humidity conditions - from -73°C to 200°C, and from 5% to 95% relative humidity (RH). Both factors can be controlled precisely, to tolerances of ±0.3°C and ±2% RH. The chamber capacity is 5 cu. ft.

The Faculty of Engineering and Applied Science also has an Ascott salt spray corrosion test chamber with 120 L (4.2 cu. ft.) capacity.
