A circuit tube tester has many uses across the automotive, electronic and computer systems industries. The right circuit tube tester for your industry will be able to handle the level of voltage you need to monitor. You should also find a circuit tube tester that can test a circuit at multiple points. This way, you can check and measure the amount of power running through any part of the circuit.

Because there are many types of circuit tube testers on the market, reputable suppliers offer circuit tube tester information on all products. You can find the right circuit tube tester for your industry by considering the following:

1. The maximum voltage of the circuit.

2. How many connections make up the circuit.

3. What type of power (AC/DC) runs through the circuit.

Action Steps
The best contacts and resources to help you get it done

Choose a circuit tube tester that tests multiple ways

When you have a variety of connections that lead back to one circuit, it's best to find circuit tube tester equipment that can test each path. Depending on the type of circuit you're working with, you can find circuit tube testers that test four ways and seven ways.

I recommend: Northern Tool + Equipment has a circuit tube tester that can test seven or four ways. You can also find many models of circuit tube testers from MSC Industrial Supply.

Purchase a continuity tester from a circuit tube tester provider

A continuity tester can test for any breaks in the circuit. It also tests how long the circuit will function once new outlets are introduced. This will help to measure how productive the circuit is, and if you will eventually need to add a second circuit to the system.

I recommend: Choose from a variety of models from the circuit tube tester list at Etcon or at the DataSwitch Corporation.

Purchase a high voltage circuit tube tester for large circuits

When you need to deal with high voltage circuits, choose the right tool for the job. A low voltage circuit tube tester will not give you the best results, and indeed would probably malfunction if you tried to use it in a high voltage situation. Instead, invest the money in a high voltage circuit tube tester to maintain your high circuit machinery.

I recommend: You can find many models of high voltage circuit tube testers from Testers and Tools, including a model that makes no contact with the circuit itself for added safety. Autobarn has a high/low voltage tester manufactured specifically for the automotive industry.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Circuit tube testers can be expensive, especially when you get to the high voltage models. Make sure you buy a circuit tube tester that's just powerful enough for your application, so you don't spend more money than necessary.
