Testo 770-1 True-RMS Handheld Hook-Clamp Digital Multimeter 600VAC/DC, 400AAC/DC

Product Description

The Testo 770-1 True-RMS Handheld Hook-Clamp Digital Multimeter (0590 7701) features a hooking clamp to separate and grab wires, with an easy hook-off retractable post. It measures AC/DC voltage and current, resistance, capacitance, and frequency. Suited for electrical work in HVAC applications, it automatically selects the correct meter configuration.

• Measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, and continuity
• Captures inrush (starting) current and performs diode testing
• Automatically detects AC/DC for volts/amps and selects correct range

Product Highlights

The 770-1 is ideal for HVAC technicians, featuring TRMS, starting current, and frequency measurement. Its unique hook-on function allows hands-free wire handling.
