Overview
JIANGKAI NBC-HW-50 (-20 ℃) Constant Temperature and Humidity Chamber is a test equipment used to simulate constant and alternating heat and humidity environment. It is mainly used for high temperature, low temperature and alternating humidity cabinet testing of parts and materials of electronic, electrical, household appliances, automobiles and other products to inspect their performance indicators and adaptability.
Features
1. Adopt full-tight Compressor imported from France, with environmentally friendly refrigerant R404A, to form an efficient and stable refrigeration system.
2. Equipped with the original 7-inch Chinese LCD touch screen controller (TEMI880) imported from Korea, the operation interface is friendly, and it supports programmable control of temperature and humidity and Linear dispersion display.
3. High control system accuracy, temperature control accuracy of +/- 0.1 ℃, humidity control accuracy of +/- 1% RH.
4. Large program capacity, capable of storing up to 100 sets of programs, with a total of 5,000 program segments, and with power-off memory and automatic connection functions.
5. The inner box is made of stainless steel plate (SUS #304), and the insulation layer is made of rigid polyurethane foam and Glass cotton to ensure good temperature Stability and energy saving effect.
Principle
The equipment precisely controls the temperature and humidity of the air in a closed test chamber through a refrigeration system (Compressor, condenser, evaporator, etc.) and a heating and humidification system. The control system drives actuators such as refrigeration, heating, humidification, and dehumidification according to the set program, so that the environment in the box changes according to the preset temperature and humidity Linear dispersion, so as to simulate the required high temperature, low temperature, constant heat and humidity or alternating heat and humidity test conditions.
Applications
Electronic, electrical, household appliances, automobiles and other product parts and materials environmental adaptability testing
Standards
GB5170.2, 3, 5, 6-95 "basic parameters of electrical and electronic products environmental test equipment method of verification low temperature, high temperature, constant heat and humidity, alternating humidity cabinet test equipment", GB 2423.1-89 (IEC68-2-1), GB 2423.2-89 (IEC68-2-2), GB/T 2423.3-93 (IEC68-2-3), GB/T 2423.4-93 (IEC68-2-30)
Steps
1. Set the required temperature and humidity program, time, and number of cycles through the touch screen controller.
2. Put the sample to be tested into the test chamber and close the box door.
3. Start the equipment, and the control system will automatically execute the setting program to control the operation of refrigeration, heating, humidification, and other systems.
4. During the operation, the actual value of temperature and humidity, the program Linear dispersion and the remaining time can be monitored in real time through the screen.
5. After the program runs, the device can stop or enter the standby state according to the setting, and take out the sample for inspection.
Notice
Equipment should be operated and maintained by professionals.
* The environment in which the equipment is placed should be well ventilated and away from heat sources and flammable materials.
Before testing, make sure that the sample placement does not obstruct the air circulation in the chamber.
* Do not open the door frequently during operation, so as not to affect the temperature and humidity accuracy and equipment life.
Regularly check the refrigerant, Filter and other components to ensure the normal operation of the equipment.
The equipment is equipped with alarm functions such as over-temperature, and faults should be promptly checked when an alarm occurs.
When conducting a humidity test, make sure that the humidification water is pure water to prevent scale from affecting the humidifier's operation.
