An Excellent tool for preparing older cars & vans for MoT and troubleshooting emissions issues on more recent vehicles. A much better design than the older gas tester with an analogue dial and a separate gas analyser that was very sensitive to orientation. Digital display makes readings clear, although direct sunlight can obscure it. Easily solved by placing the unit in the shade. The output is stable and consistent and reacts in a measured way to mixture changes. Pricing is high in my view. I bought my first gas tester for £40 and this one would have been £130+ . I don't think inflation accounts for the difference.
