LEEC Salt Solution Humidity Cabinets have stainless steel interiors and adjustable stainless-steel shelves. All SF models have sealed chambers making them suitable for humidities up to 98% RH. CFC-free Polyurethane insulation provides very efficient thermal stability in the chamber. Two 12mm access ports are provided as standard.

Monitoring and controlling both heating and cooling functions are performed with great accuracy, achieving typical temperature stability of ±0.5°C. The microprocessor-based digital display allows the temperature performance to be easily verified and a digital over-temperature safety cut out is fitted to all models.

Salt-type SF models rely on forced evaporation from pans/trays on the chamber floor, containing known saturated salt solutions which is a simple and reliable method of humidity control. As an alternative, the chamber itself can directly hold a greater volume of the saturated salt solution if pans/trays are not desirable.
