An earth ground tester is a vital piece of equipment that can save your life. With the ability to give electrical currents a safe path, it’s crucial that you have a ground tester that works well for you. With the ability to measure Earth current, continuity and leakage along with ground bond, earth ground testers are an essential tool for all electricians.
While there are many earth ground testers available on the market right now, there are a few that are a cut above the rest. Below you will find the 6 best earth ground testers for electricians:
Fluke 1630-2 FC Earth Ground Tester
The Fluke 1630-2 FC Earth Ground Tester is the very latest model in the Fluke 1630 FC range. Offering users more reliable and more accurate results, this particular tester has two versions.
You can purchase the base model or the model that comes with a Fluke Connect capacity.
Offering a selectable band-pass filter which helps to filter noise and a stronger, larger jaw, this particular ground tester makes taking readings so much easier.
Additionally, users can collect readings without having to drive auxiliary test stakes.
Completely compatible with the Fluke Connect app, the 1630-2 leaves little to be desired.
Fluke 1625-2 GEO Earth Ground Tester
The Fluke 1625-2 GEO Earth Ground Tester is known as a “one of a kind” tester, thanks to its ability to take four types of measurements. With the ability to take:
- 3 and 4 pole fall of potential when using stakes,
- 4 pole soil resistivity resting when using stakes,
- Selective testing when using 1 clamp and stakes,
- Stake less testing when using 2 clamps only,
the 162502 GEO is an impressive piece of equipment. The kit comes complete with the Ground Tester, a quick reference guide, a user manual, six 1.5 volt AA batteries and a USB connection cable. The rugged carry case that comes with the Ground Tester as standard is ideal, as it ensures the equipment is protected when not in use.
With adjustable limits, automatic frequency control and an IP56 rating, the 1625-2 GEO is set to impress.
Fluke 1623-2 GEO Earth Ground Tester
The Fluke 1623-2 GEO Earth Ground Tester comes with a design that is specific to earth loop resistance testing when you’re using clamps. Easy to use and ideal for extended use, the 1623-2 is known as one of the latest generation testers. Complete with 2 clamps, one is used for measuring results and the other clamp is used to induce voltage.
The Fluke 1623-2 GEO has the ability to test:
- 3 and 4 pole fall of potential when using stakes
- 4 pole soil resistivity testing when using stakes
- Selective testing when using 1 clamp and stakes
- Stake less testing when using 2 clamps only
Complete with an LED screen for easy readings, this particular earth ground tester is rugged and comes complete with a carry case, IP56 rating and USB data transfer and storage.
Fluke 1630 Earth Ground Clamp Meter
The Fluke 1630 Earth Ground Clamp Meter makes ground loop testing simple and allows you to measure ground loop testing along with leakage current measurement without being intrusive.
Considered to be intuitive and simple, the 1630 saves time as you do not have to disconnect or de-energise the system.
Complete with a carry case that’s quite sturdy and a 9 volt battery, you’re good to go. With the ability to measure ground leakage from 0.2 mA up to 1,000 mA, this is the ideal meter if you want to do a bit of troubleshooting.
The display hold button is ideal for capturing readings in those hard to reach places. With automatic self-calibration and overload protection, the Fluke 1630 Earth Ground Clamp Meter means business.
Beha – Amprobe DGC-1000A Clamp Ground Resistance Tester
The Beha – Amprobe DGC-1000A Clamp Ground Resistance Tester looks slightly different from the products we have seen so far on this list. With an on-board memory and complete with data logging features, this resistance tester is thought to help you become more efficient.
With individual data point recording, a large LCD display and a continuity beep, this tester is a very good one.
Individual data point recording comes as standard, as does a true-rms current measurement.
Complete with high and low ohm audible alarms and a low battery indicator, this tester seems to have it all.
Beha Amprobe KMP7010 Earth Ground Resistance Tester
The Beha Amprobe KMP7010 Earth Ground Resistance Tester has a very modern look which sets it apart from all the other testers we have seen so far. Ideal for validating and measuring a ground system’s resistance, the KMP7010 comes with a large display, test leads and a built-in memory that stores 20 measurements.
With a low battery indicator and auxiliary electrodes, the KMP7019 also comes with data hold. This is a ground resistance tester that is set to impress.
What to Consider when Buying an Earth Ground Tester
There are many impressive earth ground testers on the market, but the above 6 seem to be the best out there. If you want a tester that does the job well, you should consider choosing one of them.
This post is part of a series for electricians:
- Best digital multimeters
- Best Clamp Meters
- Best Earth Ground Testers
- Best Pat Testers
- Best Electrical Testers
- Best Insulation Testers
When you’re about to buy an earth ground tester, you need to make sure that it has all of the features you need. Do you need to test sites for any soil resistivity? If you need to do this on a regular basis, you’ll need a tester that allows you to do precisely that.
You will also need to consider the types of ground systems that you’re going to test. You will need to make sure that you purchase a tester that comes with leads that are currently too long for the job you need them to do.
Finally, you will need to consider how you will use the measurement data. This can determine which instrument you end up buying. Newer models can store results, and using a USB connection cable you can download the data to a different device. If you do not need to use this option, you may want to buy an alternative model.
