Overview
JIANGKAI NBC-HW-1000 (-20 ℃) Constant Temperature and Humidity Chamber is a test equipment used to simulate high temperature, low temperature and constant heat and humidity, alternating heat and humidity environment. It mainly conducts environmental adaptability tests on parts and materials of electronic, electrical, household appliances, automobiles and other products, and inspects its performance indicators.
Features
1. The core refrigeration Compressor adopts the fully dense Compressor imported from France to ensure stable and reliable low temperature performance.
2. The control system adopts the original 7-inch full Chinese LCD touch screen (TEMI880) imported from Korea, which is intuitive to operate and supports both temperature and humidity program control and Linear dispersion display.
3. With powerful program control function, it supports up to 100 sets of programs, 5000 steps, and has power-off memory and automatic continuation functions.
The use of environmentally friendly refrigerant R404A meets environmental requirements.
5. The inner box is made of stainless steel plate (SUS #304), which is sturdy and durable.
Principle
The equipment uses the refrigeration system (including Compressor, condenser, evaporator, etc.) and heating and humidification system to precisely create the required temperature and humidity environment in the closed test chamber. The control system collects the temperature and humidity data in the box through the PT100 temperature sensor, and precisely adjusts the output of the cooling, heating, humidification and other executive components through the PID algorithm, so as to realize the precise control of the temperature, humidity and its change process required by the test.
Applications
Electronic, electrical, household appliances, automobiles and other parts and materials of constant heat and humidity, high temperature, low temperature and alternating humidity cabinet test
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.
2. Put the test sample into the test chamber and close the box door.
3. Start the set test program on the controller.
4. The equipment runs automatically, and the temperature and humidity Linear dispersion and program execution status can be monitored in real time through the screen.
5. After the test is completed, the device stops or stands by according to the setting, and the sample is taken out.
Notice
The equipment should be installed in a well-ventilated place without direct sunlight and away from heat sources.
Do not use this equipment in flammable, explosive or corrosive environments.
When placing the sample, ensure that the air duct circulation in the box is not blocked, and the load should not exceed the specified capacity.
• Regularly check the refrigerant pressure and clean the condenser dust to ensure good heat dissipation of the equipment.
• When the equipment is running, do not switch the box door frequently, so as not to affect the temperature and humidity stability and Compressor life.
• When conducting a humidity test, make sure that the humidification water is pure water to prevent scale from affecting the humidifier's operation.
• When the equipment malfunctions and alarms, please check the fault information displayed by the controller first, and follow the prompts to troubleshoot before continuing to use it.
