Electricians and technicians, this digital earth ground resistance tester is some serious equipment for proper electrical safety testing. It measures earth resistance from 0.01Ω all the way up to 2000Ω with ±2% accuracy - that's pretty precise for field work. It also tests earth voltage up to 600V AC. The rechargeable lithium battery (7.4V 2600mAh) means you're not constantly buying batteries, which is always a plus. It uses the rated current change-pole method for resistance testing with a measurement current of 3mA max at 820Hz. Here's what's really cool - it stores up to 400 sets of data and has a USB interface so you can upload everything to your computer for analysis and reporting. The package includes two auxiliary earth rods (Φ10mm×150mm) and five testing wires in different lengths and colors. There's even a wire resistance verification function to ensure accurate measurements, plus alarm functions and overload protection for safety. The unit itself measures 280x260x160mm and weighs about 4520g with packaging - substantial but still portable for field use. If you're working with electrical systems, lightning protection, or any application where proper grounding is critical, this tester gives you professional-grade capabilities without the professional-grade price tag. It's one of those tools that pays for itself by ensuring your electrical installations are safe and compliant with standards.
