The CMEXpert2 Kit provides a Hygro-I probe for internal concrete relative humidity testing that can be reused and rechecked for accuracy every time. The Hygro-I probe is left in place during the testing period and allows immediate readings to be taken after the acclimation time required by ASTM F2170. This kit allows the user to plot locations and time versus RH. Tramex Ltd. 970-488-1898. www.tramex.ie
