SEW 1820 ER 3 Wire Digital Earth Resistance Tester
₨ 34,000
The latest SEW 1820 ER 3 Wire Digital Earth Resistance Tester price in Pakistan is Rs. 34,000/- updated on October 20, 2026.
OVERVIEW:
- The SEW 1820 ER meter is used to measure the ground resistance to 2000 Ω using a two-wire circuit (RUGBT mode) and a three-wire circuit (EXACTLY mode), as well as a step voltage up to 200 V.
Features:
- Capable of measuring earth resistance and earth voltage.
- 2 mA measuring current permits the testing of earth
- resistance without tripping earth leakage current
- breakers in the circuit under test.
- The test leads are supplied as standard accessories for
- simplified two-wire measuring system.
- Battery operated.
- Data hold function.
- Low battery indication.
- Calibration performed with supplied test leads.
