I picked one of them little meters up about a month ago Mario; just to try out. It's ok for a handy carry round. I'm still struggling to trust it against my Protimeter though. Every time I've got it in hand taking readings, I think, I'm trusting this cheap piece of kit against my Pro and every time I just go and get my Pro Habit and doubts I suppose. It truly looks like something you'd win at a fair ground.. Keep meaning to do a little comparison. The readings I've took with it have been sound on bits of timber here and their (including taking controls).. The way it'll test will be the same as the Protimeter - simple electrical resistance between the pins - but with these cheaper readers, I worry about the obvious manufacturing quality and how long it'll be before it falls out of calibration. Then you're running blind... Personally chaps, If you're serious about your game I wouldn't bother. Stanley do a pin meter for around £50 though Mario. That might be worth looking at for some of the lads..
it's always going to be difficult with lots of different views, i personally don't think a lower value product will suffice when you're looking at the most vital part of the job.
Gents, while you all may have a preference for different electronic meters, British Standards only recognise a Calibrated Hygrometer box, correctly sealed to the substrate for the defined equilibrium period, and readings recorded. Protimeter with RH probes inserted in to a hygrometer box, correctly sealed and recorded is also acceptable. All scan modes on any electronic machines are used to highlight the dampest areas to know where to position the Hygrometer. Most sub floor prep companies will use the Protimeter for invasive rh sleeve methods, and issue a spec accordingly, this is the quickest method (equilibrium) and they will put their cock on the block. MMS is a great machine, MMS2 is as good with added features, as you all say chaps...pricey!!
The tramex cmexpert is better than the mms/mms2 but both will do the same job and the protimeter blank boxes cost less.
We use protimeter mini with the prongs. Is fine for the moment. Looked at the Tramex and will get one when we expand to fitting.
You definitely need better than the pin meter if you'll be installing Conrad. Pins only tell you what's happening on the immediate surface (of concrete). You'll need to assess what's going to be bubbling up from the core and biting you on the ar*e or cock :lol::lol::lol: Pin meters don't really cut it on concrete IMO but are good to get a broader or prior idea of moisture and can impress the sh1t out of customers. Then when you start bringing out the hygro boxes or sleeves; they either start looking at you like you're about to pull their pants down or they're crawling over themselves to give you the cash :lol: - Cock, slight generalization their that isn't really true but I'm in a writing mood Anyway, pins are very much required for timber sub-floors and also measuring the flooring timber MC. You probably know all that anyway.
@Wes Thanks for the input and when we move on to installation we will look at better things. As we only sand or scrubber dry floors at the moment I don't see the need to spend that kind of money, especially, as you say, you do tend to impress the customer even with a pin meter. If the hall/place has condensation in the windows, the boards are tenting and the heating isn't on for 95% of the day, as you might be able to tell I deal a lot with village halls, then common sense is all you need to determine that there is a moisture problem.
I compared readings with a cheap pin metre & MMS at the week end on a bit of log for a burner. Reading on the cheap meter where quite a bit higher not accurate at all ! You get what you pay for
ive had the following: Protimeter aquant Protimeter Hygromaster Protimeter MMS Promtimeter MMS 2 (didn't have it long tho) I now use the Tramex CMEX Hygro-I flooring kit, and its simple, precise and does every job I need it to. I got mine from here: http://www.tradediscountshop.co.uk/...-test-and-the-new-hygro-i-in-situ-probe-work/
Mario, did you get a call/contact from a guy regarding a tramex kit? If not, he will be getting in touch soon. Recommended it and from the trade shop.
