testo 310 II Combustion Analyzer HVAC – Combustion Leak Tester for Temperature, Flue Gas & Pressure – Natural Gas Leak Detector with Smart App and Probe

It comes with a hard case and is made of high-quality material. The tube is not highly flexible, but it's flexible enough to use in small spaces. It connects very well with the phone app, allowing you to detect all the details and gas leaks. Additionally, it comes with other components so you can adjust the top of the detector. Not only does it have great quality, but it also works very well.

$500 plus service required every three years, doesn't matter how much you use it. The sensors have a shelf life.

I have two of these things and both have Error 4. One of them is barely new and the other one had the error at only 4 years, and I only use them during winter. Expensive stuff for no apparent reason 😑 🙃

So I already own the original 310 model which is very similar to this one, except I wanted this model in particular for the Bluetooth option to be able to connect your phone and use it like that as it would come in handy I figured but after spending six hours, trying to figure it out, I finally gave up as it simply would not connect to my phone And work in the app at all in no matter what I would do making a complete waste of money

Testo combustion analyzers are well known, respected and trusted. This is a huge step forward, 30 second warmup, easy to use menu, definable analysis modes and reports and above all, bluetooth with a companion app which allows you to email detailed combustion, gas pressure, and ambient CO reports to the customer. The only additional feature I would love is the ability to pair the 310 II to any bluetooth receipt style printer, it may be there but I have yet to discover it.

Nunca leyó las ppm una lastima.. Se tuvo que devolver..

this is a great instrument. It has good accuracy and enough range to get all the test data to commission or tune any appliance.
