Delmhorst Instrument Co. introduces a new meter for the restoration contractor, IAQ specialist, general contractor, and flooring installer. Total Check integrates both our pin and pin less technologies. Delmhorst’s new Total Check is a three-in-one moisture meter that enables you to identify problem areas in all building materials by quickly scanning large areas. Use the pin-mode to locate the exact source of moisture. You can also measure humidity and temperature using the RH sensor.

Delmhorst’s TotalCheck 3-in-1 meter measures moisture by pin and scan modes, and is fast acting, accurate, thermo-hygrometer. The removable RH sensor measures ambient temperature and RH, and calculate dew point and GPP. High levels of ambient humidity can be a warning sign at inspection jobs. RH is also a major concern when testing a concrete sub-floor. To address this concern, TotalCheck is designed to conform to the ASTM F-2170 standard to determine RH in a concrete slab using in-situ probes. Using TotalCheck to follow the ASTM F-2170 will provide useful information to minimize moisture-related flooring problems and failures.
