Overview
JIANGKAI NBC-HW-225 (-40 ℃) Constant Temperature and Humidity Chamber is a test equipment used to simulate constant heat and humidity, high temperature, low temperature and alternating heat and humidity environment. The equipment 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. Adopt fully dense Compressor imported from France, environmentally friendly refrigerant R404A, equipped with fin condenser and evaporator, and refrigeration system with capacity control.
2. The control system adopts the original Korean imported TEMI880 full Chinese 7-inch LCD touch screen, which supports simultaneous program control of temperature and humidity, Linear dispersion display and fault alarm display.
3. The controller has high accuracy, temperature +/- 0.1 ℃, humidity +/- 1% RH, with 6 sets of PID control parameter setting and automatic calculation function.
4. Large program capacity, up to 100 sets of programs, a total of 5000 segments, support power-off memory and automatic connection execution after power-back.
5. The inner box is made of stainless steel plate (SUS #304), the insulation layer is rigid polyurethane foam and Glass cotton, and the box door is equipped with three vacuum layers observation window.
Principle
The equipment precisely controls the temperature and humidity of the air in a closed test chamber through the refrigeration system (Compressor, condenser, evaporator, etc.) and the heating humidification system (heating rod, humidification tube, etc.). The control system adjusts the power of cooling, heating and humidification through PID algorithm according to the preset program, so that the environment in the box reaches and maintains the set temperature and humidity conditions to simulate the various heating and humidity environments that the product needs to withstand.
Applications
Electronics, electrical, household appliances, automobiles and other parts and materials of constant heat and humidity, high temperature, low temperature, 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. Perform conversation input through the touch screen to set the required temperature and humidity program and time.
2. Put the sample to be tested into the test chamber and close the box door.
3. Start the program, the device starts to run, and the screen displays the execution program number, segment number, remaining time and temperature and humidity Linear dispersion in real time.
4. During the test, the operating status and alarm information can be monitored through the screen.
5. After the test, the equipment stops running according to the program and the sample is taken out.
Notice
Equipment needs to be operated by professionals and ensure that the power supply meets the requirements.
When placing the sample, do not block the air duct in the box to ensure smooth air circulation.
Check whether the refrigerant, waterways and electrical connections are normal before operation.
When the equipment is running, do not open and close the box door frequently to avoid affecting the stability of temperature and humidity and the lifespan of the equipment.
If a fault occurs, you can troubleshoot it through the fault information displayed on the screen, or contact a professional to deal with it.
Perform regular equipment maintenance, such as cleaning Filters, checking refrigeration systems, etc.
