Fieldpiece HS35 Multimeter — Auto/Manual Ranging for HVACR
The Fieldpiece HS35 gives HVACR pros fast, safe, one-hand testing. It works with all Fieldpiece accessory heads, includes a magnetic hanger, detachable silicone leads with alligator clip tips, and packs the ranges you use every day. Built-in temperature (K-type), microamps DC for flame rectification, capacitance, and smart safety features make it a reliable go-to on site.
