Detailed Product Description

UL2594 High Precision Temperature And Humidity Test Chamber For Environmental Testing

Product overview:

Standard: according to UL2594-2016, IEC60068-2-1:2007, IEC60068-2-2:2007, IEC60068-2-30:2005.

Samples and restrictions: Parts and materials for electronic appliances, food, automobiles, rubber and plastic materials, metals and other products, such as optical fibers, LCDs, crystals, inductors, PCB, batteries, computers, mobile phones, rubber, plastics and other products.

Application: It is used to conduct cold resistance, heat resistance, moisture resistance, and dry resistance tests on raw materials and devices such as electronics, electricians, electrical appliances, and plastics. The purpose is to confirm the reliable performance of products during storage, transportation, and use in high and low-temperature alternating humid and hot environments.

Test principle: Use heating, humidification and refrigeration systems to control and change the ambient temperature and humidity in the chamber, simulating the ambient temperature, humidity and alternating procedures required by the product

Structure and features:

This machine adopts a closed chamber structure and has the following features:

A. It has a very wide temperature and humidity control range, which can meet the various needs of users. B. Adopt a unique balanced temperature and humidity adjustment method to adjust the ideal temperature and humidity environment. It has stable and balanced heating and humidification capabilities, and can perform high-precision and high-stable temperature and humidity control.

C. Automatic selection of refrigeration circuit: The automatic control device has the ability to automatically select and operate the refrigeration circuit according to the temperature setting value, so that the refrigerator can be directly started for cooling under high temperature. The refrigeration uses an air-cooled compressor unit and a fully enclosed compressor (imported). .

D. The door is equipped with a lighted observation window, which can easily observe the test status of the test sample.

Usage environment: Power supply: 220V or AC380V±5%/50Hz, 7KW

Main system components
Chamber	The inner chamber is made of SUS304# stainless steel plate with rounded corners, smooth and easy to clean.
	The outer chamber is made of 304# brushed stainless steel plate with rounded corners, smooth and smooth, and easy to clean.
	Test hole: The inner and outer chamber are equipped with a threading hole with a rubber plug
	Insulation material: polyurethane foam
	Observation window: Double-layer explosion-proof tempered glass door
	Shelf: Made of 304 stainless steel, the shelf is removable
Heating system	Heating method: electric heating
	Heating element: Ceramic heating frame, high temperature resistance, good insulation, no leakage and short circuit. The heating wire imported from Germany is connected in the middle. The wire diameter is thick, high temperature resistance and dry burning resistance. A quartz glass tube is placed in the middle of the heating wire. Its important function is to prevent the heating wire from softening and falling when it burns red, causing the heating wire to contact the metal of the inner chamber and causing a short circuit and other malfunctions.
	Thermal circulation: forced circulation air duct ensures the transportation of heat generated by the heater, prevents excessive local temperature and ensures the temperature requirements in the working room
Humidification system	Humidification method: The external humidification structure is used to transport the humidification through the air duct. The advantage is that the speed is stable and has little impact on the temperature of the inner chamber, thus ensuring a stable temperature rise and ideal humidification effect.
	Humidification tube: It adopts U-shaped design and an over-temperature probe hole. The heating wire and heating system are of the same imported brand. It has the function of preventing dry burning, ensuring that the humidification tube has a long service life and is durable.
	Humidification and water replenishment: The chamber is equipped with a drawer-type water adding chamber. The liquid level display scale of the circulating water tank can visually observe the water level. It adopts automatic water level control and water shortage alarm.
Cooling System	Refrigeration method: compressor-heat exchanger air-cooling refrigeration
	Main components of refrigeration: 1. The compressor adopts French Taikang brand and uses environmentally friendly refrigerant. 2. The expansion valve and electronic valve are both made from Danish Danfoss 3. The oil and filters are all made from Emerson in the United States. 4. Use American Ice Bear brand as refrigeration oil. 5. The pipelines used in the refrigeration system are all made of red copper, which has the advantage of good flexibility, not easy to break, and has the best shock-absorbing effect on the long-term vibration characteristics of the refrigeration system. 6. The evaporator and condenser are all well-known domestic brands.
	Cold air circulation: forced circulation air duct ensures smooth return and supply air and ensures uniform temperature in the studio
Control System	Touch screen: TIME880, South Korea Sanyuan
	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, select this mode and set the required temperature, humidity, and running time. Program test: When the test environment requires multiple temperatures, select this mode to set the temperature and running time of each program, set the program running sequence, and use 100 program groups.
Data storage	With a temperature curve interface to record data changes and processes, with a standard R232 interface or U disk communication interface, 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
