UNI-T UT33D+ Palm Size Digital Multimeter 600V AC/DC 10A with NCV, Backlight & 2m Drop Proof
Couldn't load pickup availability
The UNI-T UT33D+ is a palm-size, manual-ranging digital multimeter with built-in non-contact voltage (NCV) detection. It measures AC/DC voltage up to 600V, DC current up to 10A and resistance up to 200MΩ, plus diode and continuity tests – all in a 206g body built to survive a 2-metre drop and rated CAT II 600V. A practical everyday meter for electricians, air-conditioning technicians, maintenance crews, electronics repairers and DIY users.
Key Features & Benefits
- NCV detection – find live wires and sockets without contact; on-screen bars and a faster buzzer show stronger fields.
- 2m drop tested – rugged housing with a protective cover, test probe holder and test lead hanging groove.
- CAT II 600V safety – designed to IEC 61010 with double insulation; fused 10A and mA/µA inputs.
- Wide resistance range – 200Ω to 200MΩ, plus diode test (2.1V open-circuit) and loud continuity buzzer.
- Clear 66 x 51 mm LCD – 2000-count display with backlight (auto-off after 30 s) and data hold.
- Over-range alarm – buzzer sounds continuously above 600V or 10A input.
- Ready to use – batteries included; 15-minute auto power-off (can be disabled) and low-battery warning; runs on 2 x AAA.
