UNI-T UT133B Digital Multimeter

High-Precision 6000-Count LCD Display: Clear 6000-count digital display providing fast sampling rates (4 times/second) for clear visual inspection of live electrical parameters.

Integrated Non-Contact Voltage (NCV) Sensor: Optical and acoustic non-contact voltage detection safely identifies live AC voltage conduits without making direct contact with exposed wiring.

Dedicated 1.5V & 9V Battery Tester: Built-in battery load testing mode that quickly displays battery health status ("Good", "Low", or "Bad") under real operating loads.

Broad Multi-Parameter Diagnostic Functions: Accurately measures AC/DC voltage (up to 600V), DC current (up to 10A), resistance (up to 60 M ohms), and capacitance (up to 9.999 mF).

Rugged 2-Meter Drop-Tested Construction: Features a shock-absorbing ergonomic body structure certified to withstand accidental 2 m drops onto workshop floors.

Audible & Visual Overload Warning: Built-in acoustic buzzer and display alerts notify technicians immediately during over-voltage or over-current conditions.

Housing & Hardware Construction: Flame-retardant double-insulated ABS housing equipped with a backlit display, built-in test lead holders, and a protective rear tilt stand.

Safety Ratings & Specifications:

Safety Standards: Certified to IEC 61010 CAT III 600V.

Power Supply: 2 x 1.5V AAA batteries (R03).

Cleaning & Handling: Wipe the housing and LCD screen with a soft microfiber cloth. Keep test leads clean and free from oil, dirt, or debris.

Maintenance Recommendation: Regularly inspect lead tip insulation for cracks or wear before measuring high-voltage circuits. Always ensure capacitors are discharged prior to testing resistance or capacitance.

Essential Commercial & Residential Troubleshooting Meter: Position as an indispensable, palm-sized workhorse DMM for electricians, facility maintenance crews, and electronics hobbyists.

Key NCV & Battery Test Advantages: Highlight its dedicated $1.5\text{V}/9\text{V}$ battery testing function and built-in NCV sensor, offering quick diagnostic checks for household and industrial power tasks.

Recommended Cross-Sell Add-ons: Pair with Uni-T Test Lead CAT III 1000V/CAT IV 600V 20A, 1 Pair Small Test Hook Clip to Banana Plug, UNI-T UT116C SMD Tester Multimeter, and UT-203 Digital Clamp 3 3/4 Ohm DMM DC AC Multimeter.

High-Volume Category Staple: An ideal core featured product to highlight within your digital multimeters and handheld electrical diagnostics collection pages.
