GTC505
Engine Ignition Analyzer

Canadian flag with caption

  The GTC505 Engine Ignition Analyzer is a handheld instrument designed from the ground up for the diagnosis and performance measurement of all types of spark ignition systems, from conventional to the newest Coil on Plug in use.

  Capable of displaying and measuring the following in real time: secondary ignition waveform, primary coil current ramp time, dwell time, spark burn time and RPM. It also provides two innovative and unique display formats used to compare measurements between cylinders, and to look at data for hundreds of spark events over time in order to detect intermittent problems, misfires and other performance issues which are very difficult to detect using conventional scopes.

  This hand held device is powered by a rechargeable lithium battery, which provides up to 8 hours of battery life and uses a fast response 3.5" color TFT display with a bright backlight and wide viewing angle.
