LEEC’s humidity cabinets have stainless steel chambers and adjustable stainless-steel shelves. SF chambers are sealed and watertight making them suitable for humidity levels up to 98%. CFC-free Polyurethane insulation provides very efficient thermal stability in all models. Two 12mm cable access ports are fitted as standard for safely inserting monitoring probes into the chamber for temperature / humidity monitoring.

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

All /RH models are fitted with an ultrasonic fine mist humidity generator located at the bottom of the chamber. The microprocessor humidity controller accurately monitors and adjusts the chamber humidity level. All /RH models can de-humidify as well as increase humidity. Please note that not all combinations of humidity and temperature are possible. Temperature and humidity performance vary according to the combination selected.
