Pen phase detector with measurement of phase sequence
HT70 is a practical innovative pen device capable of carrying out, further to the phase detection function, a phase sequence and phase concordance test with LED indications and buzzer, also on the insulating sheath of the conductors.The result of the test is indicated by the red LED (incorrect phase sequence) or the green LED (correct phase sequence) turning on, by simply moving the sensor first on the L1 and then on the L2 phase.
