System Main Composition
Chamber Body	The inner chamber is made of SUS304# stainless steel plate, rounded shape, smooth, easy for clean
	The outer chamber is made of A3 cold-rolled steel plate electrostatic double-sided spray or SUS304 stainless steel
	Lead hole: inner and outer chambers are equipped with a threading hole with a rubber stopper
	Insulation material: polyurethane foam
	Observation window: double-layer explosion-proof tempered glass door
Heating System	Heating method: electric heating
	High quality nickel-chromium wire electric heater, contactless control (SSR)
Humidification System	Humidification method: external humidification structure
Cooling System	German Bock semi-tight compressor or German BITZER semi-compact compressor
	Non-fluorine environmentally friendly refrigerant R404A R23, in line with environmental regulations, safe and non-toxic.
	Shell and tube condenser (water cooled).
	High-performance fin type automatic load capacity adjustment, long-term use of low temperature and high humidity conditions without frosting.
Control System	Touch screen: Weinview programmable temperature and humidity controller (7 inch 16-bit true color touch screen)
	Temperature control: PID self-tuning, using Class A PT100 platinum resistance sensor
	Function: fixed value test and program test Fixed value test: When the test environment requires only a single temperature and humidity, selecting this mode to set the required temperature, humidity and running time. Program test: When the test environment requires multiple temperatures and humidity, select this mode to set the temperature, humidity and running time of each program. User can set the program running sequence. The program group is up to 100 groups.
Data Storage	With temperature and humidity curve interface, with standard R232 interface or U disk communication interface, the data can be downloaded, and the data changes and processes can be recorded.
Safety Protection	Power-off memory function, phase sequence protection, leakage protection, over-temperature protection, compressor overload protection, water shortage alarm, abnormal protection
Safety Protection Device	Heater air-burning protection switch, heater over current circuit breaker, circulating fan over current overload protection
	Compressor high voltage protection switch, compressor overheat protection switch, compressor over current protection switch
	Under-reverse phase circuit breaker, no-fuse switch, zero-crossing gate fluid power controller
Alarm Indication	When the above protection occurs, the equipment stops running, an audible and visual alarm is issued, and the fault location is displayed on the meter.
