Description
Fieldpiece SC640 True RMS HVAC Clamp Meter with Swivel Head, Inrush, 400A
Rotating Swivel Clamp Head for Easy Viewing at Any Angle
The SC640 is a fully loaded HVAC clamp meter designed for everyday electrical and thermal troubleshooting. It features a swivel clamp head for easy viewing, built-in test lead storage, a magnetic strap, and a backlit dial for working in low-light conditions. The SC640 provides the core measurements HVAC/R technicians rely on, including True RMS voltage and current, inrush current, capacitance, temperature, duty cycle, and microamps DC for flame sensor testing.
