SC45 Mini Clamp Meter with Temperature by Fieldpiece

The Mini Clamp Meter with Temperature for HVACR professionals, model SC45, incorporates a lot of big meter functions into a compact, easy to use design. While it's not exactly an all-in-one multimeter, this manual and auto ranging DMM includes most of the ranges you use in HVACR everyday. Along with standard multimeter ranges, we designed the SC45 to include capacitance (MFD) and temperature with great compensation. And to add to that, we designed it with built-in non-contact voltage and a continuity beeper to give you a powerful HVACR meter that's under 8-inches tall. Makes a great backup or a solid performer for everyday testing.

Like all of our test instruments, the main benefit of the SC45 is that it was designed specifically for HVACR field service. It's rugged, has built-in safety features and includes most of the ranges you need for everyday testing. Some of the highlights include:

  • Temperature
  • Capacitance (MFD)
  • 400AAC
  • Non-contact Voltage
  • Hold
  • Volts AC
  • Volts DC
  • Resistance (Ohms)
  • Continuity
  • Rugged ABS case
  • Ergonomic shape
  • Auto power-off
  • Compact size
  • Works with any accessory head
  • Autoranging
