Must have for servicing furnaces.
I was able to use this to confirm a cracked heat exchanger on my old furnace. I also used it to confirm my new furnace was working correctly.

Quality
Please don't buy! I opened it right away and turned it on and gave me O2 sensor code and will not work. I called Testo and they said the O2 sensor needs to be replaced and will not cover it under warranty. I bought three and they are all the same! Don't recommend buying these!

Easy to use, good battery life, decent display
Works well for residential systems, able to quickly tune furnaces and boilers for optimal AFUE. I routinely get 83-86% out of standard 80% furnaces after using this tool. Make sure you know what values to look for when balancing a system, such as excess air percentages and O2/CO2/CO levels, etc. Nice to be able to take static pressures on duct work as well as temperature splits, although the temperature readings take a while to even out. Easy to use, easy to switch from propane to nat gas, only gripe is that it didn't come with the printer. Do yourself a favor and buy the kit that includes the printer. Easy to prove your readings instead of writing down values on your invoices.

Easy to use...Fixed my furnace issues in 10 minutes.
Easy to use.... but $$$. But sometimes you have no choice. I got this because I was having serious problems with my Gas Furnace and after 3 attempts with professionals ($$$$$) fiddling with the Gas Control without testing the exhaust, I ordered the the Analyzer. It took me roughly 10 Minutes to read the Manual and another 10 to set the combustion correctly. Great product...

Works great
Works great. Had to buy the printer separate because they were out of kits. Maybe splurge and buy the one compatible with the app though

Not Satisfied with the Testo 310 Analyzer Kit at All
Received the Testo 310 Analyzer Kit on 1/18/25. Went through the manual and watched a couple of YouTube videos which were very helpful. Then the 310 Analyzer started taking 4 calibration cycles ending with an error code of E06 which means Sensor will be soon worn out > Contact Tesco Service. Should not have this issue with a new 310 Analyzer Kit. Emailed technical support on 1/22/25 and it is now 1/26/25 and have not received any response. Question the quality of the 310 Analyzer Kit and definingly the technical support which obviously has nowhere to be found. Will be returning the 310 Analyzer Kit.

初めて使いましたが!
以前はホダカ製を使用していましたが使用開始の手間はこっちの方が多いですね。 でも問題は有りません。

New, but must be old stock. Not a full year of calibration.
Only 6 months worth of calibration
