Equilam’s Salt Spray Test Chamber meets ASTM B117, ISO 9227, JIS Z2371 and among others, as following the ASTM B117 construction, the chamber must have a thermometer and thermostat to control the chamber’s heating. Equilam’s Chamber temperature is controlled by a temperature sensor inside the chamber to control the uniform, indirect heating by the water jacket. The temperature control devices are done by PLC’s or temperature controller with a PID control. It guarantees a temperature stability and uniformity, with a variation between +/- 0.60ºF (0,33ºC) and +/- 0.90ºF (0.50ºC) wich happens inside the chamber among the specimens.
