Jlab Export is a leading Earth Tester (Complete Set) Manufacturer,and suppliers in India
Earth Tester (Complete Set) (code EL-LE-11723) is a digital earth resistance tester, model JL129/013, that measures earthing resistance on ranges from 0–20 Ω up to 0–4000 Ω by the 2-wire or 3-wire method, and reads AC earth voltage to 400 V on a 4000-count backlit display. Electricians and electrical labs use it to check earth pits, lightning conductors and equipment earthing. JLab builds this tester in Ambala, India.

Two-Wire or Three-Wire Testing
The simple 2-wire method measures between the electrode under test and an existing reference earth, and suits quick routine checks. The precise 3-wire method works with two auxiliary stakes set in a line away from the electrode, which takes lead and contact resistance out of the result and makes it the method for commissioning a new earth pit. Manual ranging holds the meter on one range across a run of pits, and the case has double insulation.
Frequently Asked Questions
Can readings be saved for a report?
Yes. The tester stores 20 groups of data and has data hold, so a series of earth pits can be measured on site and the values written up afterwards.
Why measure the AC earth voltage first?
Stray AC voltage on the earth system, read up to 400 V at 50 Hz or 60 Hz, can disturb the resistance reading, so it should be checked before a resistance test.
