The BENETECH GT5105A is a digital earth (ground) resistance tester for checking earthing pits of houses, factories, solar systems and transmission towers. It supports accurate three-wire measurement with test spikes and a quick two-wire method.
It measures ground resistance from 0.01Ω to 2000Ω and ground voltage up to 200V, warns on screen if the C or E lead has poor contact, and has a backlight and data hold.
Key Features
- 🌍 Ground resistance 20Ω / 200Ω / 2000Ω
- 📌 3-wire precise or 2-wire simple measurement
- ⚡ Ground voltage to 200V
- ⚠️ Bad lead-contact warning on the LCD
- 💡 Backlight, data hold, battery check
