SC440 – Essential Clamp Meter

When we say all-in-one, we mean it.

Where to Buy

Sturdy magnetic strap
True RMS
Inrush current
Test-lead holder

True RMS Clamp Meter with Temperature, Inrush Current, Capacitance and Backlight – All-in-one HVACR meter – model SC440
The mid-size essential clamp meter has virtually every parameter for electrical and thermal HVACR testing in one meter.  This auto and manual ranger includes a host of safety features including a high-voltage LED and beeper, a continuity warning, push button non-contact voltage (NCV), a lead holder with detachable leads, and alligator probe tips for easy one-handed testing. As far as ranges go, it has temperature, capacitance, microamps DC for flame diode tests, and everyday electrical ranges for HVACR. Not to mention it is one of the most durable meters in the industry.

Designed specifically for HVACR field service, the SC440 is a digital multimeter that offers specific features and benefits to HVACR field service pros including:

  • Volts AC/DC
  • True RMS
  • Inrush current
  • Duty cycle %
  • 400 amps AC
  • Magnetic strap
  • Dual display
  • Temperature F/C
  • Capacitance
  • Microamps DC
  • Frequency via leads and clamp
  • Non-contact voltage
  • 50 Mega Ohm with 0.1 resolution
  • Continuity
  • Diode test
  • Hold
  • Clamp probe holder
  • LCD backlight
  • Low battery indicator
  • Hi-voltage Warning

  • Test leads: Use UL listed test leads that comply to UL61010-031 rated CATIII 600V or above
  • Included test leads are gold-plated and have removeable safety caps
  • Does it have a fuse I can change

    • No, the new meters do not use a fuse anymore. They use a PTC as it is faster and safer for the technician.

  • What the diSC mean

    • If dISC is displayed, the capacitor is not discharged completely.

  • What is NCV

    • Use NCV to check for 24VAC from a thermostat or live voltage up to 600VAC. Always test on a known live source before using. A three segment graph and RED LED will display the presence of voltage. The audible beep increases from intermittent to continuous as intensity of field (EF) increases.
