Electromagnetic anechoic box/Shield box/Anechoic chamber
The necessity of a wireless system test has risen by the spread of recent wireless telecommunication equipment as shown in cellular phone, wireless LAN, RF-ID tag and ETC (Electronic Toll Collection system). It is necessary for a wireless test to be performed in anechoic environment in which an external noise is intercepted and a radio wave does not reflect internally. An anechoic chamber (room version of a shield box) is proper facilities but needs a wide space and a huge cost. Especially, the equipment under wireless system test on the production line can not radiate any signal radio wave outside before approval. The shield box satisfies these conditions.

Anechoic chambers
The anechoic chambers are built up as a modular construction. Due to individual modules any size of chamber can be manufactured. Big chambers may require an outer supporting structure or alternatively the shielding material can be attached direct to the building. The absorbers are fixed to rails bars or wooden base construction which is inserted into the shielding modules.

Tapered Anechoic Chamber
It’s nearly impossible to perform VHF/UHF measurements in a rectangular chamber. In the 1960’s Emerson determined that tapering one end of an Anechoic Chamber would cause the chamber to act like an indoor ground reflection range.Tapered Chambers work very well at the lower frequencies. Their design forms a uniform illumination across the test region. The tapered end of the chamber forces the wall images close together forming a source antenna array. Tapered Chambers are usually a less expensive option compared to rectangular antenna measurement chambers or compact ranges.

Up to 6 measurement values and messages can be displayed via its graphical color display. The colors of the display can be adjusted individually. Alarms, such as faults, exceeded limit values, or warnings are highlighted on the CRP5 display, and can also be forwarded digitally via MODBUS, Ethernet, or relays. Thanks to its analog and digital communication capabilities, the CRP5 is very easy to integrate in any monitoring system. Its comprehensive functional capabilities allow the CRP5 to be configured perfectly for each application. The CRP5 is distinctive in the marketplace through its tough glass front plate and a removable humidity sensor.

Insect Rearing Rooms
Standard walk-in incubators or coolers used in the rearing of drosophila and other biological organisms often end up being problematic for a number of reasons. The acids inherent in the rearing of many specimens or their food can quickly corrode a standard refrigeration evaporator. High humidity exacerbates the issue, as droplets of concentrated acid will collect on the cooling components.
