Concrete and Mortar Moisture Meters

HI520-2 Concrete and Mortar Moisture Tester

Non-Destructive Moisture Testing — Concrete, Mortar, and Building Materials The HI520-2 measures surface moisture in cured concrete, mortar, and a range of building materials in seconds. No drilling, no coring, no sample prep — place the sensor on the surface and read the moisture content directly. Built for construction sites, finishing and coating prep, and quality control in building material manufacturing.
  • Six built-in calibrations: Concrete, mortar, lightweight concrete, gypsum board, ALC, and calcium silicate board — one instrument for the materials you actually test.
  • ±0.5% accuracy on concrete and mortar: Repeatable readings to verify spec compliance before flooring, coating, or finishing work.
  • Eight user calibrations & 1,000-reading memory: Build custom curves for materials outside the factory list. Each reading is date and time stamped for documentation.
  • Backlit display, single-hand operation: Larger LCD with adjustable backlight for low-light measurement. Push-button controls replace the older HI-520 dial system.

HI520 Concrete and Mortar Moisture Tester

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 The HI520 has been replaced by the HI520-2, which adds a backlit display, push-button controls, onboard data memory with timestamps, three additional material calibrations, and eight user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.

HI300 Fresh Concrete Moisture Meter

Instant Moisture Readings on Freshly Mixed Concrete — Before the Batch Cures The HI300 measures moisture content in freshly mixed concrete in under five seconds. Drop a sample into the cup, press the button, read the result. No waiting for loss-on-drying ovens, no batch sitting on hold while results come back. Built for ready-mix plants, jobsite QC, and any operation where moisture decisions need to happen at mix speed.
  • ±0.5% accuracy on fresh concrete: Factory-calibrated capacitance measurement matches loss-on-drying results without the wait.
  • Three-second response per sample: Test the batch, log the value, release the load. No production delays waiting for lab confirmation.
  • 126-reading onboard memory: Track moisture across a shift or a pour. RS232C output for batch records and QC documentation.
  • Built for the plant floor: No moving parts, vibration-tolerant, orientation-independent. Runs on AC or six C-cell batteries for portable use.

HI330 Aggregate Moisture Meter

Instant Moisture Readings on Sand and Aggregate — Before It Goes Into the Mix The HI330 measures moisture content in sand and aggregate in under five seconds. Drop a sample into the cup, press the button, read the result. Built for ready-mix plants and aggregate suppliers who need to dial in water-cement ratios accurately — not estimate them based on yesterday's stockpile reading.
  • ±0.3% accuracy on aggregate: Factory-calibrated capacitance measurement gives you the precision needed to adjust mix water with confidence.
  • Three-second response per sample: Test the stockpile or hopper feed, get the value, adjust the batch. No waiting, no guessing.
  • 126-reading onboard memory: Track moisture across stockpiles, shifts, or weather changes. RS232C output for QC records.
  • Built for the plant floor: No moving parts, vibration-tolerant, orientation-independent. Runs on AC or six C-cell batteries for portable stockpile work.
