YG751E Humidity Control Box is also named environmental test chamber, climatic test chamber, can be applied to test the properties of heat-resistance, cold-resistance, dry-resistance and humidity resistance of materials. It is mainly used in testing the adaptability of electronics, electrical appliances, food, automobile, rubber and plastic, metal and other products, parts and materials in the high and low temperature and humid environment when storage, transport and using.
Main technical parameters:

Notes: Environment temperature:+25℃; R.H.≤85%
This two values measured under the condition of no test sample in the chamber
3℃/min (Room temperature to high temperature 150℃); 1℃/min (room temperature to minimum temperature).
Balanced temperature & humidity control mode, PID programmable adjustable.
RS232 print interface.
Fully enclosed Tecumseh compressor France original, environmentally friendly refrigerant gas R404A.
Has adopted Korean TEMI850 controller English display, 120 program x 100 step and 100hours/step setting capacity (each step means specific temperature, humidity and test time), 999 cycles circulation setting, and enclose multiple sets of PID control function.
SUS#304 stainless steel material
1.2mm thickness SUS#304 stainless steel, rigid polyurethane foam+efficient ultra-fine glass cotton insulation materials.
1. IEC6008-2-1-2007 Electronic Electrician Product Environmental Test Part 2: test methods --Test Method A: low temperature.
2. IEC68-2-3 Ca test: constant humidity and heat test method.
3. IEC6008-2-30:2005 Db test: humid heat alternation method.
Air Circulation System
Inner air circulation fan, wind channel and stainless steel cycle fan, through the top window and air diffuser, the wind will out uniformly from the top, which could reach the purpose of control temperature uniformly.
Adopt heating pipe P.I.D. control the heating so keep temperature balance.
Adopt outside water circulation humidification, and compressor is used for dehumidification, P.I.D. control the volume of humidification.
Water level protection, water shutdown protection, over-temperature protection, high-pressure compressor protection, compressor thermal protection, compressor overload protection, fast fuse, buzzer alarm, overload protection.
Door of Chamber
Single open door, anti-explosion, anti-condensation electric heating device, vacuum auto-defog transparent window, window internal bulb.
Test Lead Hole
Φ50mm, enclosed with relative temperature preservation and heat insulation parts.
