Legendary ruggedness meets versatility. The Amprobe 37XR-A offers true RMS accuracy, electronics-focused features like capacitance and frequency, plus extras such as logic and component testing. It’s a great balance between affordability and professional-grade capability.
Overview
The Amprobe 37XR-A is designed with electronics troubleshooting in mind. While it has the safety rating and current handling to be used around power systems (CAT III 600 V / CAT II 1000 V), its strength lies in component-level work. With dedicated measurement modes for capacitance, inductance, frequency, and even transistor/logic testing, it stands out as a versatile tool for engineers, technicians, and serious hobbyists.
Key Features & Specs
- True RMS for accurate AC measurements
- CAT II 1000 V / CAT III 600 V safety rating
- 4,000-count display with bar graph
- Measurement functions:
- – Voltage (AC/DC)
- – Current (µA to 10 A)
- – Resistance, continuity, diode test
- – Capacitance (µF to mF range)
- – Inductance (mH range)
- – Frequency & duty cycle
- – Logic & TTL/CMOS testing
- Data hold, relative mode, min/max/average recording
- Auto/manual ranging
- Backlight and protective holster
Pros
- Excellent value for an electronics-focused multimeter
- Wide range of component measurements (capacitance, inductance, frequency, logic)
- True RMS ensures trustworthy AC readings
- Solid build with protective holster
- Suitable for both bench and field work
Cons
- 4,000-count display is lower resolution compared to premium meters
- Limited logging or advanced filtering features
- Not as rugged or drop-resistant as Fluke’s industrial models
- Slightly bulky compared to compact handheld hobby meters
Who It’s For
- Electronics engineers and repair technicians
- Hobbyists who work with circuits and components
- Technicians needing a versatile all-rounder
- Anyone looking for more than basic voltage/current checks
Verdict
The Amprobe 37XR-A is a strong choice for anyone who wants a general-purpose multimeter with a real focus on electronics features. It doesn’t quite reach the rugged durability of high-end Fluke industrial models, but in return it offers measurement options they often don’t include. For bench engineers, repair techs, and hobbyists who want a single meter that covers almost everything, the 37XR-A is a smart investment.⭐ Ratings (out of 5 stars)
