I haven't used the EXTECH product so don't know about it. For our use on a Cat gas engine, we aren't talking about needing anything but a good reliable tool; not anything really high tech for these low pressures.

There are better exhaust analyzers on the market but they cost a lot more than the Testo. Testo has done a lot of work to produce a reliable and versatile analyzer at a reasonable cost. Many Cat dealers and gas engine customers buy the Testo for their techs. Testo has several models. I like the model with the wireless handheld display. It makes the process somewhat safer and more convenient.

I probably would consider a Dwyer brand instrument; this company has been in business a long time and the products are very dependable. The Model 475 Digital Manometer seems to be the most popular. But you should go to their website and check out the features of all the digital manometers and see which one fits your needs.
There are probably other reliable brands besides Dwyer but I have liked their products for many years.
