Fieldpiece HS33 Expandable Manual Ranging Stick Multimeter for HVAC/R

Rugged, ergonomic design built for HVAC/R field work

Meet Fieldpiece HS33, an expandable manual ranging stick multimeter designed for both professionals and students in HVAC/R. Its updated, ergonomic shape sits naturally in the hand, while the textured grip and protective rubber bumpers help it withstand harsh conditions on the job. A magnetic hanger keeps the unit easily accessible as you connect test leads or assess components, enabling a more efficient workflow in tight spaces or on a busy job site.

Broad testing capabilities for HVAC/R tasks

The HS33 expands your measurement toolkit with ranges for VAC, VDC, AAC, and ADC, plus a dedicated temperature input via a K-type thermocouple plug. It includes a diode test and a non-contact voltage (NCV) tester, giving you quick situational insight without contacting live conductors. Real-time data features such as MIN / MAX and Data HOLD help you compare readings over time and spot trends during troubleshooting.

• Non-contact Voltage (NCV) for quick live checks
• 400 A AC current capability and capacitance measurement
• High voltage and continuity indicators for fast pass/fail decisions
• MIN / MAX and Data HOLD to capture fluctuations
• Temperature measurement enabled by a K-type thermocouple plug
• Diode test for quick component verification

Designed for both field work and classroom use, the HS33 ships as a complete kit that supports hands-on learning and on-site diagnostics. In addition to the meter itself, you’ll find essential accessories that make testing more flexible and portable, so you can adapt to different work scenarios without hunting for tools.
