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 The HI520 has been replaced by the HI520-2, which adds a backlit display, push-button controls, onboard data memory with timestamps, three additional material calibrations, and eight user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.
Legacy Model — Replaced by the HI-520-2
The HI510 is a handheld non-destructive moisture tester for concrete, mortar, and ALC. It uses high-frequency capacitance to read surface moisture without sample damage. The HI510 has been replaced by the HI520-2, which expands the calibration list, adds a backlit display, push-button controls, onboard data memory with timestamps, and eight user calibration slots.
Non-Destructive Wood Moisture Meter (Moco II) — No Longer Manufactured
The HM530, also known as the Moco II, measured wood moisture through surface contact using high-frequency capacitance, leaving no pin marks. It has been replaced by the HM540, which carries the same non-destructive method forward with a wider species range and added data logging.
Non-marking measurement: read moisture through the surface without driving pins into the wood.
Wide range: 2 to 150% moisture content across more than 400 species.
Replaced by the HM540: the current model adds 999-point memory, USB logging, and JHWTC certification.

The HI500 is a handheld non-destructive moisture tester for concrete, mortar, and ALC. It uses high-frequency capacitance to read surface moisture without sample damage. The HI500 has been replaced by the HI520-2, which expands the calibration list, adds a backlit display, push-button controls, onboard data memory with timestamps, and eight user calibration slots.
Handheld Pin-Type Wood Moisture Tester — No Longer Manufactured
The MT100 was a compact, handheld resistance moisture tester for woodworkers, lumber handlers, and shop environments. It read moisture by needle probe across a broad working range, with selectable calibration and a built-in correction chart for species variation.
Pin-type resistance: Direct moisture reading via needle probe penetration
Broad working range: 6–40% moisture content on a dry basis
Pocket-portable: 280 g with simple two-AA power for shop or field use
