The Total Check 3-in-1 moisture meter integrates pin mode, pin-less scan mode, and thermo hygrometer into a fully featured meter for flooring installers.  Total Check identifies problem areas in building materials using the pin-less scan mode to quickly survey large areas, and then locates the exact moisture source using pin-mode, the company says. Additionally, the thermo hygrometer measures relative humidity and temperature of the air, giving a complete picture of the test environment.
