Panel mount digital multimeter
SMY, SMZ
KMB Systems
SMZ devicePanel Measuring and Registering Instruments
These devices are ideal for application where monitoring and recording of voltages, currents, power factors, frequency, powers, harmonic distortion of voltage and current, energies etc in three-phase LV, HV, VHV grids are required. It can also measure and record temperature. All measured values are stored in the instrument and can be later downloaded for processing using a remote communication line. SMY device has a bright LCD display and features meny userfriendly wiews on the recorded data. SMZ unit has a LED display for rough environments and embedded electronic electricity meter for more precise energy monitoring.
