We bought this for our electricians to use in an industrial facility. This meter allows us to be faster at finding bad wires and motors. It has helped us to become more reliable and sustainable, within our company, so we can obtain less downtime on our production floor. We also use this product as a preventative maintenance tool on all our critical equipment. Great product!

The Fluke 1503 arrived in perfect condition and performed exactly as expected. I ordered the tester from TE Equipment and it arrived in less than 24 hours. The staff was very knowledgeable and helpful and the price could not be beat. I would highly recommend TE Equipment for any future tester needs.

Tequipment is an excellent place to purchase, fast shipping. Great pricing. The meter is Fluke which is Top of the line. I always buy Fluke, they stand behind what they sell
We bought a couple of these units and issued it to our electricians. They were happy because it is easy to use. They immediately put it in action and find a lot of issues on the plant.
Fluke quality at a great price. This is a good, solid IR tester and was well priced. It is of the usual Fluke quality.
Happy with product. Good price
Fluke products are a industry standard, and widely used by electricians worldwide. Simple to operate, and the digital screen is easy to read.....
Bought this to install a Ditra heated floor. Very happy with the purchase and the shipping speed. Got here quicker than the estimate expected!!! English manual online, no issues in use... heated floor works!
This is a no brainer for me. I am an Electrician and my insulation tester needed replacing. I have other Fluke meters so it had to be another Fluke. Why pay pay 3 times the price and it was delivered to Australia in about a week. Initially I was concerned about the Chinese writing on the box but the meter is in English and works good like a Fluke should.
