C.A 42 LF Fieldmeter

ca42 lf fieldmeter
The C.A 42 fieldmeter is specially designed for measuring electric and magnetic fields in the low-frequency range (0Hz-400kHz) and comparing the values measured with the requirements of the European directives and international standards. They can be used in both public and private contexts, as well  electromagnetic compliance  tests of electrical equipment in industrial environments.

Description

 
The Chauvin Arnoux C.A42 LF Fieldmeter measures magnetic fields and currents and also compares its results to European standards, in order to see whether an appliance or installation is safe. The magnetic field meter uses four internal isotropic probes, and a single external probe, to detect and measure magnetic fields. It can measure frequencies of up to 30kHz (it can be extended up to 400kHz with the use of external magnetic field probes), and its readings are accurate to around 5%.

The electrical field meter is very easy to use thanks to its simple format and hand-held design. The buttons on the body of the device each have a single function, and are clearly labelled, in order to minimize confusion and error during use. The external probe is easy to disconnect when not in use or for storage purposes. When the Chauvin Arnoux C.A42 LF Fieldmeter has taken its readings, the results are displayed on the LCD backlit display, meaning your results are always easy to read, regardless of the lighting conditions.

The electric field meter is a pleasure to use as it weighs just 950g and measures 266 x 144 x 60 millimetres. The device requires NiMH batteries, and the battery life can last up to six hours.
