Environmental Chamber Calibration Services | Here is a short video to make you understand how Wewon Environmental Chambers Co., Ltd. help their customers. Sometimes, There plenty of customers who is take care of the nine point temperature test procedure. According to this, Wewon ordered the calibrate engineer from Huizhou TaiZheng Measured Instruments Service Ltd Dongguan Branch coming for temperature and humidity calibration work.
We have recorded the nine point temperature uniformity test, and the humidity test by videos when the calibrate engineer working there. So the customer who is too much concern about the nine point temperature and humidity test will pleasure on what we have supplied to them.
Wewon environmental chamber is a better choice than China other supplier. Because Wewon is the only certificated supplier from China on the Global Environmental Test Chambers Sale Market Report 2017. There has many customers from 28 different countries bought environmental chambers from Wewon in the past 10 years.

Environmental Chamber Testing Purpose : Environmental chamber can accurately simulate the complex natural environment of low temperature, high temperature, high temperature and high humidity, low temperature and low humidity. Bacteria, microbial culture, fermentation, various thermostatic test, environmental test, water analysis, BOD determination, microbial culture material denaturation test and storage of medium, serum, drugs, etc.
Environmental chamber is widely used in medical and health, electronics, semiconductor, medicine, chemical industry, cosmetics, coating, biological pharmacy, agricultural scientific research, environmental protection and other research and application fields.
How to maintain the environmental test chamber ? When you are in an environmental chamber testing laboratory, You may need the environmental chamber insulation or environmental chamber testing services. The below are some guidance which may helpful for you when you are processing the environmental chambers repair work. Try to find local environmental test chamber manufacturers and inquiry their benchtop and walk in environmental chamber price is a good idea !
1. The refrigerating system (France Tecumseh Compressor), condenser parts shall be maintained regularly and kept clean. Dust sticking the condenser will make the environmental chamber compressor high pressure switch jump off and produce false alarm, the condenser should be regularly maintained every month. Use a vacuum cleaner to remove the dust on the condenser heat release screen or use a hard brush or a high-pressure air nozzle to blow the dust clean after starting the environmental chamber.
2. The overtemperature protection device of distribution box set data, Please don’t revise without environmental chambers manufacturers permission. This protection switch is used to protect heating tube and humidifying tube from air burn-out and water shortage alarm. Set Point = Temperature Set Point (+20℃～+30℃)
3. When environmental chamber is working, temperature in the test room rises to the set point of the over-temperature protector, the power supply of the heater will be stopped and the over-temperature warning light will be on, but the fan will still be running. If the over-temperature protector is running for a long time and unattended, Before operation the environmental chambers next time, Please make sure to check the overtemperature protector, whether it is set properly.
4. Water pipes in waterways are easy to block and leak. Please check regularly whether there is water leakage or water plugging. The stored water in the humidifier in the small environmental chamber shall be replaced once a month to ensure the water quality is clean and the flow is smooth.
5. When the test sample is taken out after the time is up, the environmental chamber for battery testing must be shut down and the staff must wear dry, electricity-proof and moisture-resistant gloves.
6. When opening and closing doors or taking test objects from the environmental chambers, Do not let the test samples touch the glue edge on the door, in case the glue edge is damaged and the service life is shortened.
7. The ground around environmental test chamber shall keep clean at all times to avoid accidents and performance degradation caused by dust inhalation into the unit.
8. The freezing system is the core of the environmental chamber. Please inspect all copper pipes once a year to see if there is any leakage of Freon. Please inform the environmental chamber factory in casa there any oil leakage of horn joints and welding joints.
9. The distribution area shall be cleaned and overhauled at least once a year. Loose contact points can put the environmental chamber service in a dangerous working state. It may burning components, personal injury also possible, when cleaning please use a vacuum cleaner will be indoor dust absorption can be removed.
10. Humidifier should clean always, so as not to produce scale, It may affect the release of steam. Generally do one test and cleaning once, scale get timely elimination and beneficial for humidifying pipe’s life, to ensure the smooth flow of water.
11. When wet bulb gauze surface is dirty or change to hard, or make a temperature above +85 ℃ test always, Please try to use a new wet bulb cloth and replace the old one.
12. Environmental Chamber Maintenance Service. If there is any non-absorbent status, please replace it. Because it may occur the test accuracy problem. The wet bulb gauze should be replaced once every three months. When replacing the wet bulb gauze, Wash your hands before washing the water tank where put the wet bulb gauze there.
13. Check and adjust the water level of the wet bulb: The water level of the water-collecting cup shall not be too high, Because the water will overflow the water-collecting cup, But too low water level will make the wet bulb gauze has problem to water absorption. Keep the water level about 60% full. Adjust the water level of the water collecting cup, then you can adjust the height of the water storage cup. [Friendly Tips: adjust screws on both sides]
