Legacy Model — Replaced by the HI520-2
The HI520 is a handheld non-destructive moisture tester for concrete, mortar, lightweight concrete, gypsum board, and ALC. It uses high-frequency capacitance to read surface moisture without sample damage. The HI520 has been replaced by the HI520-2, which adds a backlit display, push-button controls, onboard data memory with timestamps, three additional material calibrations, and eight user calibration slots.
