In July 2022, our Calibration Laboratory received accreditation with the number AP 209 granted by the Polish Center for Accreditation (PCA) under the EA MLA international agreement. Thus, the Laboratory confirmed compliance with the requirements of PN-EN ISO/IEC 17025 "General requirements for the competence of testing and calibration laboratories" in the field of calibration of electrical quantities.
Yokogawa expands oscilloscope portfolio with 500 MHz and 350 MHz frequency band models
The APPA 98-IV is a digital meter with a maximum indication of 6,000. With the VoltSeek™ function, the device enables non-contact detection of live cables and sockets.
See the Related Products tab for available cases for the measuring device.
Automatic voltage detection with low impedance
Specially designed LoZ (Low Impedance) function prevents
false readings caused by spectral voltages,
making electrical measurements easier and safer,
as well as more reliable.
Intelligent Data Hold
The intelligently designed Data Hold function alerts the user with an
with a beep and flashing backlit display,
when the LCD reading has been paused for an uncertain operation,
to avoid accidentally touching the Data Hold.
AC+DC True RMS
The APPA 98IV & 99IV features AC+DC True RMS readouts
in both ampere and voltage functions for better
Ergonomically designed slim shape with dial
and buttons operated with one hand.
Fits seamlessly into the user's hand and needs.
Easy battery replacement
Simply unscrew one screw to remove the battery compartment
in order to replace it. There is no need to open the entire
bottom part of the housing o increase the convenience of the device.
Non-contact voltage detection
VoltSeek TM is a non-contact function that detects live wire
under voltage and outlet. It makes it possible to search for wires
