We’ve Got A New Look

As you may have noticed, things are a lot brighter around our website these days!

We hope this new site is just as easy to navigate as the old one, and we welcome your feedback. Please e-mail any comments or suggestions to *For the web-saavy users out there: Our old site was almost entirely raw HTML, with only a little Javascript for the slider, and some PHP around the (WordPress) blog. What’s the Difference?​ I don’t even know where to start! We’ve listened to your feedback, and the new website displays pricing for all our tools, and allows you to buy any of them. You can order anything, shipped almost anywhere! We are also in the process of adding pages for (most of) our parts and accessories, as we want to make sure it’s easy for you to get spares for your tools. What Else Is Going On?​ We’re planning to release two new tools by the end of the year! The first will be the “GTC107 SmarTach+ Digital Transducer”, …

Testing Oxygen Sensors

There are a few different tests for oxygen sensors (also known as lambda sensors), some of which can be run without dedicated tools. The most effective tests tend to be done under normal operating conditions, on a sensor installed on an engine system, though there are some tests which can be done off-vehicle. You can test oxygen sensors with the following tools: Multimeters Clamp-Meters Oscilloscopes The ST05 Oxygen Sensor Tester Caution: Be sure to follow the oxygen sensor manufacturer’s precautions when testing, as well as the tool manufacturer’s directions, and read the vehicle (or other system) service manual before doing any test. Oxygen sensors get very hot when in use, be careful! But wait! Before testing anything, you need to know what kind of sensor you are working with, and where it is.

How to Test Glow Plugs

Glow plugs are installed on many diesel engines to help with cold starts. They usually fail because of corrosion, overheating, mechanical damage, or metal fatigue, and their failure can cause a variety of problems. The easiest way to test a glow plug is by using a clamp-meter, though digital multimeters can also do the job, and glow-plug testers also work. We will cover the following topics in this post: What is a Glow Plug? What are the Symptoms of a Failing Glow Plug? How to Test Glow Plugs with a Clamp-Meter How to Test Glow Plugs with a Digital Multimeter How to Test Glow Plugs with a Glow Plug Tester Caution: Be careful to follow the glow plug manufacturer’s precautions when testing, as well as the test tool’s directions/manual, and read the vehicle (or other system) manual before doing any test.
