CLAMP ON AC/DC HiTESTER
3287
Compact & Easy, One-Touch Maintenance on All Types of AC/DC Equipment
Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The Hioki 3287 is an AC/DC current and voltage clamp meter that also measures continuity and resistance, featuring a double jaw lever and slim profile for easy access to crowded wires. CAT III 600 V (Current) CAT III 300 V (Voltage) CAT II 600 V (Voltage) Key Features • Accurately measure even small currents with 10 A range • Voltage, resistance, and continuity check functions
