Review: Quality u gauge up grade.. Gas men read! - I had a kane 3200, very strong and robust but played up so got rid. The testo was my 2nd choice. It has mixed reviews. I was put off by comments about the quality. I should have known better as I use testo flue analyser. It's small, neat, light, compact, easy to use. Doesn't come with hose, the nipples are quite small for rubber hose so I dug deep for the anton hose with prv (also well worth it people are bad reviewing that but I love that also) I digress 🤔🤣🤣.. Comes with sceen cover and separate carry case. It's tiny takes up no room in tool box. It's back lit if required for dark meter cupboards... If you do plenty of gas/service/repair/install don't be put off by bad reviews it's ace.
Review: The perfect manometer for gas engineers - Doing gas servicing and this manometer is perfect for the job.. it’s very small and comes with a nice case. The only dislike I have is the rubber manometer hoses are to lose to fit on properly, so I cut a bit of the plastic hose that came with it and fitted this inside the rubber hose. See pic above. Overall the best manometer I’ve owned
