The DMK 20, DMK 25 and DMK 50 digital multimeters are suitable instruments for measuring the electrical parameters of energy distribution systems or electric installations.
The immediate and clear advantage deriving from their use is that
of combining traditional voltmeters, ammeters, frequency meters and
other measing instruments in a single device.
The DMK 20, DMK 25 and DMK 50 digital multimeters can accurately measure all the electrical parameters
normally required in almost all applications.
The variety and accuracy of the measurements make them a
winning technical-cost-effective alternative to conventional analog
The DMK25 digital multimeter is particularly indicated for use with
As many as 47 measurements
are viewable and include:
Voltage (8 measurements):
Phase, line and system
9-38VDC range (DMK 25 only)
Active, reactive, phase and total apparent
Power factor of each phase
Frequency (1 measurement):
Frequency of measured voltage
Maximum (HIGH) and minimum (LOW) value
function for monitoring and recording instantaneous voltage, current and
Non-volatile erasable memory
The total and partial hour function makes them suitable for the
control boards of generating sets.
Measurement reliability is guaranteed by accurate design and the use of
a latest generation flash microprocessor. Even in the most critical
operating conditions (highly disturbed electrical ambient or
currents with high harmonic content), the measurements of DMK 20, DMK 25 and
DMK 50 are
always stable and repeat accurate.
Auxiliary supply range 154 to 288VAC (DMK 20,
DMK 50 only)
Auxiliary supply range 9 to 32VDC (DMK 25 only)
Voltage measuring range 60 to 830VAC
Current measuring range 0.05 - 6A
Non-volatile total and partial hour
Partial hour counters configurable as maintenance with
Delayed automatic resetting function of default
Averaging function for stable voltage
and current viewing
Current input with ARON configuration
via 2 CTs only
Single, two and three-phase wiring
with or without neutral
TRMS measurements up to 22° harmonic level.
