Morning all, My new Tramex meter is here, being used to reading in RH (Balls Digital Hydrometers) I am wondering if the is a comparison guide (i.e.. 74%RH = ??? in MC).
dont use a tramex but i think it depends on what it is your taking a reading from sand and cement 6.4 is the equivalent to 75%
Took some pics a few years ago. As you can see, the rh is quite alot higher but the reading on the Tramex isn't that much different. Be careful, best to do rh test if close to 4%, definitely if above
Spoke to Tramex yesterday and there guidance was that a MC of 3.5% to 4% is about 75%RH, however they were clear to state that this is just a guide.
about 3.5 ish. However you cant compare the two readings as one is reading what amount of moisture is leaving the concrete and the other is reading moisture content by weight.
Very true. Some manufacturers say mc though and I believe that manufacturers instructions override BS. Seems a bit crazy with some of them.
Manufacturers instructions over ride BS standards if there product can do something above what BS says. As for moisture testing you have to follow BS. If a manufacturer says to test in MC then it will be a european product. What you have to do is both tests, you have to do a RH test to meet BS standards and a MC test to satisfy manufacturer .
