. W11stop.com has wide range of Industrial Meters with cash on delivery service in Karachi, Lahore, Multan, Peshawar and many other cities.OVERVIEW:
The 1120 ER is a "professional instrument". The instrument is suitable for the testing of single earth electrodes such as lightning conductors and other small earthing systems. The resistance of conductors such as continuity and conduit coupling joints can also be measured. Two-terminal operation measurement, which reduces the accuracy, can also be done by shorting P and C terminals.
Features:
- Capable of measuring earth resistance and earth voltage.
- 2mA 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.
- 0Ω adjustment.
- Battery operated.
- Data hold function.
- Low battery indication.
- Calibration performed with supplied test leads.
