Ionizers
Panasonic Automotive & Industrial Systems Europe GmbH
There are many production processes where electrostatic charges disturb smooth operation. To eliminate static, ionizers are used. One typical field of application is the semiconductor industry where the components are extremely sensitive and can even be damaged by high electric static charges. Another example is the printing industry: Here friction between the rollers and the paper generates static. The static makes the paper cling and not move correctly through the printing machine. Especially when printing on vinyl or plastics, electrostatic charges need to be removed. In the packaging industry, plastic sleeves or foils tend to stick to each other, which can be prevented with an ionizer eliminate static. A general problem in assembling processes is the adhesion of dust and dirt particles. Contamination of workpieces can be prevented by having static eliminators neutralize and blow away undesired particles.

Moisture Meters
Moisture Meters fall into two categories, pin-type and pinless. Pin-type Moisture Meters measure the resistance between test pins inserted into a piece of wood or a building material and use that reading as a proxy for the object''s absolute moisture level. The wetter the material, the less ready it is to be sanded, painted, finished or covered. A best seller is the MMD4E Pin-Type Moisture Meter. Pinless Moisture Meters rely on the ability of moisture to inductively distort an electric field created by turning on the meter. Although Pinless Moisture Meters can only make relative readings, they are nonetheless useful for pinpointing the source of a leak above a ceiling, and for leaving no unsightly pinholes on a finished surface. The MMD7NP is a best selling pinless moisture meter.

Avalanche Photodiodes
These avalanche photodiodes (APDs) are silicon photodiodes with an internal gain mechanism. As with a conventional photodiode, absorption of incident photons creates electron-hole pairs. A high reverse bias voltage creates a strong internal electric field, which accelerates the electrons through the silicon crystal lattice and produces secondary electrons by impact ionization. The resulting electron avalanche can produce gain factors up to several hundred.

GSM RF Interference Test System
Guangzhou Jumho Electric Co., Ltd.
Cell phones and other wireless devices radiate powerful electromagnetic fields that can cause interference and noise in microphone signals. The interference and noise is called RF interference, which is an unwanted “signal” that occurs at the same time and frequency as a data signal. The RF interference disrupts the flow of data and degrades quality-of-service. Jumho Electric provides a cost-effective RF interference test system for GSM interference level measurement of wireless microphone.
