HS33 Expandable Stick Multimeter 

Full Featured for HVAC & Refrigeration

  • Partners with all accessory heads to do more with one meter
  • Non-contact voltage - Built-in Volt Stick
  • 400 AAC with included Clamp Accessory
  • Convenient lead storage
  • Safe one-handed testing

The HS33 Multimeter is a great entry level modular multimeter.  Like every Fieldpiece meter, it's packed with the features and functions HVACR technicians need to get the job done. The ergonomic shape fits firmly and naturally in your hand while testing.  The magnetic hanger, detachable test leads and alligator clip probe tips, allow you to perform tests hands-free. All Fieldpiece accessory heads slide directly on top of the HS33, so you can test a wider variety of parameters than what's in a single meter.

The modular expandability of the HS33 makes it so you don't have to buy additional expensive meters to preform additional measurements like air flow, amps, static pressure, vacuum, and many more.  There are approximately 15 additional accessory heads to choose from.
