allsun Clamp Meter AC Voltage & Current Tester with NCV Data Hold EM4235 | 2-in-1 clamp meter and voltage tester, 0.5-100A AC current, 12-400V AC voltage, NCV, live/neutral ID, 3-data memory, auto-off

The allsun EM4235 is a versatile 2-in-1 electrical tester that combines a digital clamp meter for AC current measurement with a voltage tester for AC voltage detection. Whether you're an electrician, HVAC technician, or DIY homeowner, this compact tool helps you quickly diagnose electrical issues — from checking outlet voltage to measuring appliance current draw.

• 【2-in-1 Clamp Meter & AC Voltage Tester】 This digital clamp meter combines a voltage test pen and an open-jaw current clamp into one compact tool. Measure AC current and voltage without carrying multiple bulky meters—switch functions instantly to save time and tool pouch space. Power Supply is 1 pc 1.5V AAA battery.
• 【Non-Contact AC Amp Meter with NCV】 The open U-shaped jaw enables rapid AC current measurements from 0.5A to 100A—simply place a single wire into the fork without breaking the circuit or touching bare conductors. The built-in NCV (non-contact voltage) detection safely identifies live wires from 90V to 400V.
• 【Wide-Range Voltage Tester (12V-400V)】 Accurately measures AC voltage from 12V up to 400V with a sensitive built-in probe tip. Perfect for troubleshooting household outlets, HVAC maintenance, automotive diagnostics, and commercial electrical work—a versatile circuit tester for any job.
• 【Dual-Color LCD & Live/Null Wire Identification】 The clear digital screen features an intelligent dual-color backlight: turns red with a buzzer alarm when detecting high voltage (≥36V) or live wires. Instant visual and acoustic warnings ensure you never miss a hazard, even in dark breaker panels or noisy workshops.
• 【Durable Build with Data Hold & Low-Battery Alert】 Built with high-strength insulated housing and CAT II 400V safety protection. The Data Hold function freezes readings on screen for easy logging in tight spaces. Low-battery indicator alerts you before accuracy is compromised—reliable performance when you need it most.
