GM-70

MAGNETIC FIELD ANALYSER

VERSION 12/21

Nº 1665723

The magnetic ﬁeld analysis device is intended for detecting magnetic DC and AC ﬁelds. It is a highly sensitive magnetic ﬁeld

measuring device for a wide range of applications in industry, development, electronics and mechanics. It is suitable for checking

the function of energised coils, e.g. in relays, in solenoid valves, etc. Since it is a non-contact magnetic ﬁeld analysis device, in

most cases you will not need to open the housing to facilitate testing.

The sensor enables the measurement of DC and AC magnetic ﬁelds in the range 300 to 3000 mT or 150 to 1500 mT (millitesla).

When measuring DC magnetic ﬁelds, the polarity of the magnetic ﬁeld (north/south) is displayed. The high sensitivity of the

sensor enables measurement of magnetic ﬁelds for reference purposes. An RS232 interface allows forwarding and processing

of measurement data by means of an appropriate (optional) data cable.

A 9 V block battery is required for operation (included). Operation with a power adapter is also possible. The power adapter is

not included with the product.

This product is intended for indoor use only. Do not use it outdoors. Contact with moisture (e.g. in a bathroom) must be avoided

under all circumstances.
