All cabinets have stainless steel interiors and adjustable stainless steel shelves. All SF models have sealed chambers making them suitable for humidities up to 98%. SF models can have an outer door heater (OPTIONAL) to demist the inner glass door(s). CFC-free Polyurethane insulation provides very efficient thermal stability in these models. A 12mm access port is provided as standard.
Monitoring and control of both heating and cooling functions is performed with great accuracy, and achieves typical temperature stability of ±0.5°C. The microporcessor based digital display allows the temperature performance to be easily verified. A digital over temperature safety cut out is fitted to all models. The chambers are fan assisted.
Humidity Control (Salt Solution)
Salts-type SF models rely on forced evaporation from pans / trays containing known saturated salt solutions. This is a simple and reliable method of humidity control. The pans / trays sit on the chamber floor. Alternatively, the chamber itself can directly hold a greater volume of saturated salt solution if pans / trays are not desirable.
