Temperature testing methods push products to their limits, measuring how much heat or cold an item can withstand. Environmental chambers simulate harsh conditions like freezing temperatures, blistering temperatures, extreme humidity and more. Research and development departments rely on environmental chambers to determine at what point their products may stop functioning or to fulfill military standards. Recirculating baths and chillers offer temperature calibration over a wide range of temperatures. A temperature forcing system will test components like semiconductors by introducing intense thermal shocks to them, simulating an entire lifetime of use and wear in a few seconds.
