Samples and Restrictions:
Electronic & electrical appliances, food, automotive, rubber and plastic materials, parts and materials for metal and other products, such as optical fiber, LCD, crystal, inductor, PCB, battery, computer, mobile phone, rubber, plastic, etc.
It is used for cold, heat, humidity and dryness testing of raw materials and devices such as electronics, electricians, electrical appliances, plastics, etc. The purpose is to confirm the products reliability of storage and transportation under high and low temperature alternating heat and humidity.
The heating, humidification and refrigeration system are used to control and change the ambient temperature and humidity in the chamber, to simulate the ambient temperature and humidity and alternating procedures required by the product.
This machine adopts a closed chamber structure with the following features:
A. It has an extremely wide temperature and humidity control range to meet the various needs of users.
B. It adopts a unique balanced temperature adjustment and humidity control mode to adjust the ideal temperature and humidity environment. The heating and humidification capability are stable and balanced, and the temperature and humidity control are high-precision and high-stability.
C. Automatic selection of refrigeration circuit: The automatic control device has the ability of automatically starting the running refrigeration circuit according to the set value of temperature, can start the cooling directly under the high temperature state. The refrigeration adopts the air-cooled condensing unit with fully enclosed compressor (imported).
D. The door is equipped with a observation window, which is convenient for observing the test state of the test sample.
Power supply: 220V or AC380V ± 5% / 50Hz, 7KW or match client’s local power supply requirements
Ambient temperature: 5 ° C ~ + 30 ° C, there should be no high concentration of dust, corrosive gases and flammable explosive gas.

|Temperature Range (Optional)||
|Temperature and Humidity Range Scheme|
|Chamber Body||The inner chamber is made of SUS304# stainless steel plates, rounded shape, smooth and easy for clean|
|The outer box is made of 304# stainless steel plate, rounded shape, smooth and easy for clean|
|Test hole: inner and outer chamber is equipped with a threading hole with rubber stopper|
|Insulation material: polyurethane foam|
|Observation window: double-layer explosion-proof tempered glass|
|Shelf: Made of 304 stainless steel, detachable shelf|
|Heating System||Heating method: electric heating|
|Adopting the latest new ceramic heating frame, the ceramic material is resistant to high temperature and with good insulation, will not cause leakage short circuit phenomenon. The middle is connected with German imported heating wire, the wire diameter is thick, high temperature resistance and dry burning resistance. The quartz glass tube is inserted in the middle of the heating wire, to prevent the short circuit fault due to heating wire contacting metal chamber.|
|Thermal cycling: forced circulation air duct to ensure the heat transfer of the heater, to prevent local temperature is too high and to ensure the required temperature in the working chamber.|
|Humidification System||Humidification method: adopts external humidification structure, transfers through the air duct. The advantage is that the speed is stable and the influence on the temperature of the inner box is small, so that the temperature rise is stable and the humidification effect is ideal.|
|Humidification tube: U-shaped design plus over-temperature probe hole, heating line and heating system adopt the same imported brand material, with anti-dry function to ensure long service life and long-lasting durability of humidification tube.|
|Humidification and hydration: There is a drawer type water adding box. The water level can be visually observed through the liquid level display scale on the circulating water tank. The water level is automatically controlled. With water shortage alarm.|
|Cooling System||Refrigeration method: air-cooled cooling using compressor-heat exchanger|
Main components of refrigeration:
1. Uses Tecumseh compressor imported from France, which adopts R404 and R23 DuPont environmentally friendly refrigerant.
2. Expansion valves and electronic valves are the main components of the refrigeration system, all Danfoss, Denmark
3. Oil and filter are from Emerson
4. Refrigeration oil is from American ice bear. T
5. he pipelines used in the refrigeration system are all imported copper materials, which have the advantages of good flexibility and not easy to be broken and have the best shock absorption effect for the long-term vibration characteristics of the refrigeration system.
6. The evaporator and condenser are using domestic famous brands
|Cold air circulation: forced circulation air duct ensures smooth air return and air supply, ensuring temperature uniformity in the working chamber.|
|Control System||Touch screen: TIME880, SAMWONTECH|
|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 only requires a single temperature and humidity, select 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. Operator can set the program running sequences and can set up to 100 groups of programs.
|Data Storage||With temperature and humidity curve interface, the data changes and processes can be recorded, with standard R232 interface or U disk communication interface, the data can be downloaded.|
|Safety Protection||Power-off memory function, phase sequence protection, leakage protection, over-temperature protection, compressor overload protection, water shortage alarm, abnormal protection.|
