Fieldpiece SC420 Dual Display True RMS AC Clamp Meter

The Fieldpiece SC420 is an essential clamp meter for HVAC/R professionals. Auto or manual ranging, it covers the electrical ranges technicians and students use for most HVAC/R work — volts AC/DC, 400A AC, microamps DC, temperature, capacitance and duty cycle — all with True RMS accuracy and a dual display so you can read two parameters at once.

Safety features include a high-voltage LED and beeper, continuity warning, push-button non-contact voltage (NCV), a lead holder on the clamp and MAX hold so you can hook up, step back and read results safely.
