GE Protimeter meters meet ASTM standards
GE Protimeter now offers a variety of meters that conform to the new ASTM International Relative Humidity test method for determining concrete floor moisture content.
The Protimeter Hygromaster is a compact and accurate hygrometer that allows for a more effective measurement compared to calcium chloride tests, the company says. The Protimeter MMS incorporates a hygrometer as well as a pin and radio frequency moisture meter.
Protimeter hygrometers feature interchangeable Hygrostick probes that allow the user to take many ERH readings rapidly with one instrument, according to the company.
