The doors are magnetically operated

The doors are magnetically operated and remain locked while the unit is operational, ensuring a highly safe and contamination-free internal environment. They might also be provided with a lock and key arrangement for added safety.The recent models of humidity test chambers ideally have a modular construction for ease of installation and portability and may also feature an open frame module that allows integration of the unit into other environmental chambers. The equipment uses an easy to use interface and various programming and documentation systems to allow multiple programming possibilities. All the models of the equipment come equipped with an active humidity control system that consists of steam generator cylinders and steam distributors. The steam distributors ensure even distribution of steam throughout the working area, whereas the steam cylinders contain all the calcium and mineral deposits within them. The disposable type steam generator cylinders are generally preferred for these equipments as they facilitate easy maintenance and cleaning. The humidity test chambers are available in a wide variety of sizes and configurations. Each model employs an ideal heating concept, designed to provide uniform and precise control of temperature throughout the working area, irrespective of the chamber volume and the sample load. The chamber can provide a working temperature range of up to 90°C with efficient humidity control and up to 160°C without humidity. The unit also comes equipped with an indirect heating system, comprising of air heaters and an efficient cooling system, comprising of non-CFC refrigerants and compressors. The equipment is provided with efficient fans and blowers for maintaining continuous air circulation, thereby ensuring uniform distribution of temperature and relative humidity throughout the working area.The humidity test chambers are also provided with various customized shelves to allow segregation of the samples. They feature microprocessor based controllers cum indicators for temperature and humidity, ensuring highly precise operating conditions. They are also equipped with safety thermostats with PID controllers and temperature sensors and LED/LCD display for the actual and set parameters.
