The testo 750 voltage testers are the first instruments to include an all-around viewable LED voltage indication. All three models of testo 750 include low input impedance, phase sequence, continuity test, and meet CAT III 1000 V CAT IV 600 V safety standards.
testo 750-1 Digital Voltage Tester Features:
Patented all-around viewable LED voltage bar indication
0 to 690 V AC/DC voltage measurement
Polarity detection for VDC measurements
Phase sequence test for determining motor rotation
