Overview
HUDA QT-E702-100K70 programmable humidity chamber is mainly used to simulate the high temperature, low temperature or heat and humidity environment that may be encountered during transportation, storage and use of electronic Instruments, new materials, electricians, vehicles, metals, electronic products, aerospace materials, etc., inspection materials, accessories or equipment High temperature resistance, cold resistance, moisture and heat resistance performance and possible damage life reduction.
Features
1. Box structure: The inner box adopts SUS304 stainless steel plate, the outer box is Cold rolled steel plate paint, equipped with explosion-proof door handle, ultra-fine fiberglass insulation layer, double-decked vacuum heating and defrosting observation window, fixed PU movable wheel and adjustable spacing stainless steel sample holder.
2. Refrigeration system: using French Taikang Compressor and American DuPont environmental protection refrigerant, binary low temperature circuit system design, P.I.D + S.S.R temperature and humidity coordinated control, precise and stable control.
3. Heating and humidification system: heating using nickel-chromium alloy electric heating wire, humidification using stainless steel tube built-in electric heating wire, the system is independent and equipped with automatic water replenishment device.
4. Control system: Precision liquid crystal display programmable temperature controller, support multi-group multi-segment program operation, with USB data transfer interface, can be connected to computer display and print Linear dispersion.
5. Protection system: with multiple protections such as overheating of the overall equipment, overheating of the fan, underphase/inverse phase, overload of the refrigeration system, overpressure, timing, leakage, etc., and automatic shutdown after fault alarm.
Principle
The equipment simulates the required temperature and humidity environment in a closed box through the coordinated work of the refrigeration system, the heating system and the humidification system. The refrigeration system uses a binary cryogenic circuit and Compressor for cooling and dehumidification; the heating system raises the temperature through an electric heating wire; the humidification system increases the humidity by generating steam through electric heating. The control system is monitored and corrected in real time through the P.I.D + S.S.R algorithm and the PT100 platinum resistance Sensor to achieve precise control and programmed operation of temperature and humidity.
Applications
Electronic Instruments, New Materials, Electrical, Vehicles, Metals, Electronics, Aerospace Materials
Standards
GB2423.1-2008/IEC6008-2-1-2007、GB/T 2423.2-2008、GJB150.3A－2009、GJB150.4A－2009、GB2423.22-2008、GBT 2424.5-2006、GB/T 10589-2008、GB/T2423.3-2008(IEC68-2-3)
Steps
1. Move the device to the designated position through the bottom PU activity wheel and fix it.
Connect the power supply (220V) and check the equipment status.
3. Set the test program (program or set value) through the touch screen controller, including temperature, humidity, time, and other parameters.
4. Place the sample on a stainless steel sample holder with adjustable spacing to ensure uniform load-bearing distribution (≥ 20kg).
5, close the door, make sure the sealing is good.
6. Start the equipment and run the test.
7. The test process can be observed through the observation window, and the data recording and Linear dispersion can be viewed by connecting the computer through the USB interface or communication interface.
8. After the test is completed, the equipment is stopped according to the setting and the sample is taken out.
Notice
• The load-bearing capacity of the sample should be evenly distributed, and the standard load-bearing capacity of each sample holder should be ≥ 20kg.
• Before the equipment runs, ensure that the door is well sealed, and use a special sealing soft plug sealing test hole.
• The equipment has multiple safety protections, and it will automatically shut down when the fault is alarmed. It needs to be checked before rerunning.
• The humidification system is equipped with an automatic water replenishment device to ensure the normal water supply.
• Be sure to fix the casters after moving the device.
When setting the program, pay attention to the limit of 5 ° C on the upper and lower limits of the temperature setting range.
• The main electrical components of the equipment such as circuit breakers and AC contactors use the "Chint" brand, please pay attention when maintaining.
Software must be run on a compatible IBM PC and a designated operating system that meets the requirements.
