Digital Meter With LED Display
Digital meters with LED display enable fast and accurate survey of electric
quantities and are convenient for industrial use as well as for the production and
distribution of electric energy. They are panel mounted and enable measurement
of TRMS values of electric quantities.
Energy Meters With Power Display
With Power Display, display instantaneous power in single or three-phase systems with balanced or unbalanced load. Our energy meters
with power displays have housing for panel mounting. Some of them can also display momentary power in single and three phase systems
with balanced or unbalanced loads.
Analogue Meters
Active or Reactive Power Meters
Power meters are electronic meters intended for measuring active or reactive power in single phase or three-phase networks, with balanced
or unbalanced load. The accuracy class is 1.5. The scale value depends on primary values of current and voltage.
Power Factor Meters
Power factor meters are intended for measurement of power factor (cosϕ) in a three-phase three-wire network with a balanced or unbalanced
load or in a single phase network. The accuracy class is 1.5.
Pointer frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz.
Reed frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz. Two-system reed frequency
meters are intended for measurement of two frequencies in the system for synchronisation. Their class is 0.5.
Meter With Limit Contact
MI 7350 can signal minimal and maximal setting limits (MIN
and MAX). The meter is provided with two output relays of
600 VA switching power.
TAP Position Indicators monitor the voltage Tap on a transformer, hoist or valve position etc.
It employs a bridge system, using a 400Ω or 50Ω per step. The scale is entirely linear and
inter-changeable.
Meters for AC Voltage or Current with Moving Coil and a Rectifier
Meters with a moving coil and a rectifier are intended for measurement of AC currents or
voltages where a linear scale is required, in the frequency range from 40 Hz to 65 Hz
(higher frequency range on request).
The scale is interchangeable.
The accuracy class is 1.5.
Meters for AC Voltage or Current with Moving Iron
Meters with a moving iron are intended for measurement of AC currents or voltages of
frequencies from 15 Hz to 100 Hz. They measure rms values independently on the signal
form of current or voltage.
Bimetal maximum current meters with a bimetal measuring system are intended for
testing the thermal load of transformers, cables, electrical machines, etc. They indicate
average rms current value in a setting period of 8 minutes (on request 15, 20 and 30
minutes for the MQ0207 and the MQ0307). The accuracy class is 3 and the meters are
provided with an interchangeable scale. Meters in the size of 96 x 96 mm with a protecting
transformer are also available on request.
Combined Bimetal Maximum Current Values
Combined bimetal maximum current meters are provided with a built-in bimetal system
and a system with a moving iron. The meters are intended for testing momentary and
thermal load of transformers, cables, electrical machinery, etc. Meters with dimensions
of 96 x 96 mm with a protecting transformer are also available on request.
The accuracy class for average rms current value is 3, and for momentary value 1.5.
The meters are provided with an interchangeable scale.
Shunts = 50 Millivolt + 60 Millivolt.
Current Transformers
Current measuring transformers are used for measuring
Primary AC currents. The secondary current is 5A or 1A,
rated frequency from 50 Hz to 60 Hz.

Digital Meters
If you are looking for manually or semi-automatically synchronise generators and bus bars, you have come to the right place. Our
synchronization meters are truly unique products. They measure phase differences between generator and bus bar, voltages and the
frequencies of the two systems. They can replace up to five instruments, occupying less space and giving you more information, for a lower
price. Furthermore, they are equipped with status output, they are also appropriate for mounting on ships. They are equipped with LED
diodes, so you can actually see the phase difference. When synchronising conditions are set, the synchronizing relay is activated.
