The Percometer is a reliable, accurate, lightweight and easy-to-use instrument for measuring the dielectric value (εr), electrical conductivity (J) and temperature of materials indoors and outdoors. Dielectric value is an indication of the volumetric moisture content and the state of molecular bonding in a material. Electrical conductivity is a reflection of ionic concentration, water content and temperature.

Humboldt's NEW H-4112 Percometer

The Percometer can be used in performing soil moisture investigations and tube suction tests, frost susceptibility and frozen soil evaluations, as well as determining salinity/sulfate levels in soil.

Two Basic Probe Types

The Percometer utilizes two basic probe types, of which there are some variations. The surface probe has been designed for measuring tile walls, aggregate samples and liquids. While the probe utilizes non-destructive technology, its measurements have an effective penetration depth of 2-3cm, depending on the medium. The tube probe has been designed for insertion into soft materials (minimum depth 10cm required for accurate measurements) and is ideal for measuring forest soils and road subgrade.

The Percometer can utilize multiple probes with the same central unit. Each probe is identified by the central unit by its unique probe number, and uses a probe-specific calibration table in the central unit’s memory.
