They are mainly used to test the reliability of various products and components, on continuous exposure to various environmental conditions. Environmental test chambers include digital readout, analog meter or video display with test results; and provide heating and cooling effect.

There are some environmental test chambers that control emissions from various equipment under properly controlled conditions. Again there are some test chambers that subject various products, components and samples to extreme humidity, thermal cycling or extreme temperatures.

Types of Environmental Test Chambers

• Temperature Chambers
• Humidity Chambers
• Vibrations Test Chambers
• Altitude Test Chambers
• Thermal shock Chambers
• Corrosion Test chambers

Specifications of Environment Test Chambers

The various performance specifications of test chambers are:

• Temperature Range
• Temperature Control Accuracy
• Humidity Range
• Humidity Control Accuracy
• Chamber Capacity
• Chamber Style

Interface Options of Environment Test Chambers

Proper choice of environment test chambers is very essential and it primarily depends on examining user interface options.

• Various inputs like keypads, dials and switches for adjusting ranges and controlling parameters are provided with test chambers that have front panels. Analog devices include a needle or simple visual indicator. Digital readouts provide alphanumeric displays. Environmental test chambers that include a programmable logic controller (PLC) give signals to the PLC, or receive inputs from the PLC.
• Extra output options for environmental test chambers include analog voltage, pulse signals, analog current, switches or relays; and radio signals.
