Humidity chambers which have corrosion resistant, stainless steel inner chamber and housing for long-term climatic tests at constant temperature and humidity. Ideal for food processing, cosmetics, pharmaceutical, biotechnology and electronics industries. Units feature an auto diagnostic system with fault indication for temperature and humidity control. The working chamber is heated on all six sides; this together with electronic humidity control prevents condensation forming in the chamber. Distilled water is supplied from an external 2,5 litre tank by means of a self priming pump. lnternal log memory 1024 kB (ring buffer) for all relevant data, capacity is approximately three months at one minute intervals. GLP/GMP compliance is assisted by the USB interface and 'Celsius' software for programming and documentation.
- Multifunctional 'Perfect' PID microprocessor controller and digital LED display for all set parameters and seven-day program timer with real time clock
- Integrated timer for temperature profiles of up to 40 ramps, each segment adjustable from 1 min up to 999 h
- Active control for humidifying and dehumidifying (20 to 95% RH) with digital display of RH, resolution 0,5%, setting accuracy 1%
- Various safety features including independent, digitally adjustable, electronic over-temperature controller TWW protection Class 3.1 (saves the samples and the incubator); audible and visual alarm in case of over- or under-temperature, under-humidity, door open or empty water tank
- Inner glass door enables samples to be viewed without affecting chamber temperature and prevents contamination
- For all models, the inner chamber, including the ventilation system, the water trays and all sensors, can be sterilised at 160 °C in a 4 hour program using STERICard
