Electrical appliances are safety-tested on different environmental conditions to assure their safe operation.
This walk-in environmental chamber provides us with a room-size test environment where we can control both temperature and humidity allowing us to test performance and safe operation of appliances-under-test.
Shown also in this photo are the Xitron Power Analyzer and the Yokogawa MX100 Datalogger both of which are connected to a computer located at the far side (not shown).
