Klemsan MED2 series devices are MID-approved energy meters that measure and record the basic electrical parameters required for monitoring single-phase power lines. The following parameters are optionally measured in the devices. • Voltage • Current • Frequency • Active power • Reactive power • Apparent power • Power factor • THDV • THDI • 4 quadrants energy    

KLEA 5 and POWYS 6 series devices can be used to measure electrical parameters like current, voltage, frequency, harmonic, etc. in 3-phase systems.
