The Fieldpiece SC440, Essential Clamp Meter, is a mid-size multimeter that 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 non-contact button 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 degrees for HVACR. It is one of the most durable meters in the industry. The Fieldpiece SC440 multimeter is designed specifically for HVACR field service.

The dual display makes it easy to view both voltage and amperage readings simultaneously. The non-contact voltage indicator and the probe holder make electrical testing safer. The SC440 is a digital multimeter offering many features and benefits to the pros of HVACR field service.

The Fieldpiece SC440 clamp meter may be mid-sized, but it’s fully packed with features. This meter combines a backlit dual-line LCD, robust measurement capabilities, and components that make the work of HVAC service technicians easier and safer. This Fieldpiece HVAC clamp meter is fully compliant with the Third Edition of the UL61010-1, which is why the SC440’s probes come with sheaths to cover all but the tip of test leads, resulting in safer electrical measurements. Fieldpiece SC440 has virtually every parameter for electrical and thermal HVACR testing in one meter.

Q & A

Does the Fieldpiece SC440 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.

Can the SC440 fieldpiece clamp meter read volts, amps and ohms?

Yes, this meter can read volts, amps and ohms.
