What is the environmental chamber ? What are the environmental chamber’s calibration services ? If you are located in United States and looking for the environmental testing chamber manufacturers ? You can talk with Thermotron environmental chamber, Tenney environmental chamber, Hotpack environmental chamber, Russell environmental chambers … In fact, There plenty of environmental chamber manufacturers in North America area.
An environmental chamber, also known as a climatic chamber, is a piece of equipment used to test the effects of different environmental conditions on a variety of materials and components. These chambers can simulate different environments, such as temperature, humidity, and pressure, to see how different tests samples perform in these conditions. For example, a car manufacturer may use an environmental chamber to test the performance of a car in different weather conditions, such as extreme heat or cold.
Environmental test chambers have a wide range of applications, from testing the durability of electronic components in extreme temperatures to evaluating the performance of building materials in different humidity levels. They are commonly used in industries such as aerospace, automotive, and electronics to ensure that products are able to withstand the conditions they will be exposed to in the real world. In addition to testing components, environmental chambers can also be used to evaluate the performance of entire systems.

Environmental Chamber’s Calibration Services | Here is a short video to make you understand how Wewon Environmental Chambers Co., Ltd. help their customers. There plenty of customers who are care of the 9 point temperature test procedure and calibation report and approved by ilac-MAR, CNAS testing center.
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.

There are several types of environmental chambers available, including temperature chambers, humidity chambers, thermal shock chambers, altitude chambers, and vibration chambers. Temperature chambers, for example, can range from -70°C to 180°C and can maintain a specific temperature within a small margin of fluctuation. Humidity chambers can simulate different levels of humidity, while thermal shock chambers subject samples to a rapid change in temperature to test their durability.
But I have to say that Wewon environmental chambers are the better choice for you. The reason is that Wewon is the only certificated supplier from China on the Global Environmental Test Chambers Sale Market Report 2017. It is a very rare honor to be a unique supplier in China and to conduct market analysis with European equipment suppliers. According to incomplete statistics, There has many customers from 28 different countries bought environmental chambers from Wewon in the past 10 years. This is indeed a good sales performance !

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. Fore sure that try to find local environmental test chamber manufacturers and inquiry benchtop environmental chamber price also a good idea !
● | The refrigerating system, 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. |
● | 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. |
● | 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. |
● | 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. When 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 electricity-proof and moisture-resistant gloves. |
● | 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. 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. |
● | 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. |
● | 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. |
● | 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. |
● | If the wet ball gauze 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. 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. |
● | 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. |
