DMG 900... expandable digital multimeters are
available with a flush-mount housing, 96x96mm size.
The wide graphic touch screen display provides extremely simple
interacting between the instrument and the user.
The high performance of the multimeters gives very accurate
measurements and can control energy distribution systems, to detect
and prevent energy problems which could compromise quality and
supply.

installations where the measurements of various multimeters must be
remotely viewed. The DMG 900RD remote display connected to the DMG
900T transducer can display the measurements on the panel front
while power connections remain inside the panel.

The DMK 2..., DMK 5...,
types give reliable readings and measures even in the most critical
conditions such as voltages and currents with high harmonic content
and variable frequency.
The total and partial hour counter function is an interesting
feature for generating set control boards, especially the
DMK 25 and DMK26 models with DC auxiliary supply.
The variety and accuracy of the measures make these multimeters
a winning technical-cost effective substitute to conventional analog measuring
instruments.

excellent features, superior to devices of the same category currently on the
marketplace.
Distorted waveform conditions, for current and voltage with high harmonic content and variable frequency, do not influence the high accuracy DMK multimeter readouts because of rigorous
design in addition to the use of the latest generation of microprocessor
technology.
Measures of the phase angle (cosphi) as well as power factor, harmonics analysis and HIGH-LOW-MAX functions are just a few of
these, which are difficult
to find on higher category equipment.
The DMK 40 model includes a powerful and easy-to-use data logger along with the other features mentioned above.

The modular digital metering instruments DMK7 and DMK8 warrant
a extreme stability of the readouts owing to the large number of
samplings.
The measures in TRMS provide for a correct operation even in
presence of voltage and current conditions with high harmonic
content.
The metering instruments find use in single or three-phase power
distribution boards for both industrial and service fields.
All the models are able to store and display maximum (HIGH) and
minimum (LOW) values of the readouts.
There are DMK R1 types available with the same features along with
one programmable relay output.
Units equipped with a voltage measure input, consent to program the
VT (Voltage Transformer) ratio and therefore can be employed in
medium-voltage systems.
They can be used as an effective solution to replace traditional
analog instruments, that is voltmeter and ammeter complete with
relative changeover switches, with the advantage of extra panel
space.
