HI500 Concrete and Mortar Moisture Tester

Description

HI500 Non-Destructive Moisture Tester (Legacy Model)

The HI500 is a handheld high-frequency capacitance moisture tester for cured concrete, mortar, and ALC. Place the sensor against the surface, read the moisture content directly. Three factory calibrations plus two legacy CH-2 channels carrying forward from earlier Kett mortar testers. Manual and automatic temperature compensation, thickness compensation up to 40mm, hold function, and an upper-limit alarm round out the feature set.

Replaced by the HI-520-2

Kett continues to support the HI500 with parts, calibration service, and maintenance agreements, but the model has been replaced in the active product line by the HI-520-2. The HI-520-2 retains the non-destructive surface measurement workflow and adds capabilities the original HI500 did not offer:

• Six factory calibrations covering concrete, mortar, lightweight concrete, gypsum board, ALC, and calcium silicate board — three additional materials beyond the HI500.
• Backlit display with three brightness settings for low-light measurement.
• Push-button menu replaces the three rotary dials of the HI500.
• 1,000-reading onboard memory with date and time stamping on every reading — useful for compliance documentation and customer audits.
• Eight user calibration slots for materials outside the factory list. Pair with the optional HDL-01 data logger software to simplify calibration creation and export readings to a Windows PC.
• S mode for shallower-point measurement on thin boards, in addition to the standard D mode.
• Manual temperature override down to −10°C (vs. 0°C floor on the HI500).
