The top-opening, well insulated cold air chamber is mechanically refrigerated by two hermetically sealed, maintenance-free compressors, arranged in a cascade configuration. Air chamber temperature stability of ±0.1°C is maintained by a digital indicating temperature controller. The digital temperature display shows air chamber temperature to 0.1°C resolution. Additional digital temperature displays are provided for measuring test bearing temperature in the case of ASTM D4693.
