Reverberation Chambers
Over the past several decades, RCs have been enjoying growing popularity as a promising facility for the characterization of wireless devices and for EMC testing. The RC (Reverberation Chamber) measurement method exhibits much competitive superiority over the AC (Anechoic Chamber) method and TEM Cell method, such as low cost, enhanced test repeatability, a more realistic test environment, and easily achieved high-field environment. The application of the RC for performing EMC testing was first proposed by H. A. Mendes in 1968. In the recent IEC 61000-4-21 standard, the importance of EMC testing using RCs as an alternative measurement technique has been recognized.

Environmental Chambers
KB Series
Darwin Chambers KB series Environmental Chambers are a top selling unit. It is quiet, easy to clean, highly reliable and ideal for laboratory use. Our environmental chamber offers hot gas bypass control of refrigeration and resistive heat to facilitate reliable, critical temperature and humidity control. All KB series environmental testing chamber models are designed to have a temperature range of 4-60o Celsius. Temperatures greater than 60o Celsius or lower than 4o Celsius can be achieved with optional upgrades to construction and components. All KB series environmental chambers come standard with Fuji’s PXG4 microprocessor, but we often install Watlow brand microprocessors for customers that need that brand or the capabilities it has. Unlike many proprietary controllers on the market, these controllers are available off the shelf and have been proven in tens of thousands of installations. All necessary functions are included in our Features section below. Many additional options are available both regarding control and recording of data (chart recorders and loggers)

Condensation Chamber
Wewon Environmental Chambers Co, Ltd.
The condensation test chamber does not need special installation conditions, just need to connect to the ordinary power supply and running water can be used normally. The functional diversity of the equipment, fast and low operating costs make the machine a very high cost performance condensation testing machine in the market. The machine can be programmed to control three different test effects: Humidification, natural cooling and drying, and the corresponding temperature and running time of each test, and set the total time of program running and the number of cycles. The condensation tester has an automatic water replenishing device. When the water temperature exceeds the upper limit, there will be a protection device for safety warning, and it is very safe to use.https://www.wewontech.com/condensation-chamber/
