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.

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

Was deceived by photos of a hard strong case not this flimsy crap case. Very disappointed

Fast, accurate and well priced! The tester works great and was easy to figure out. The instructions were a little cryptic but once you start using it I was able to figure it out just fine. The magnet is a good strong neodymium. The printer works great with dates and times and space for contractor name and number write in. I am mostly using it for condensing boilers and water heaters. No it's not the super high end testers with the additional Sci readings but it will work for 95% of what I do need it for.

Came with 10 months on the calibration certificate. Definitely a brand new never opened unit. Very happy with my purchase

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 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.
