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. 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. 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 - 3 cm, 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. Percometer permits the use of 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. Includes surface probe. Other probes available, contact Humboldt.

Speedy® 2000 Moisture Tester (20g)

The Series 2000 Speedy Moisture Tester is a portable system for measuring the moisture content of a wide range of materials including soils, aggregates, dust and powders (and liquids). The system consists of a low pressure vessel fitted with a pressure gauge and an electronic scale and test accessories. Moisture measurements are made by mixing a weighed sample of the material with a calcium carbide reagent in the sealed pressure vessel. The reagent reacts chemically with water in the sample, producing acetylene gas that in turn increases the pressure within the vessel. The pressure increase in the vessel is proportional to the amount of water in the sample, the moisture content can be read directly from the calibrated pressure gauge. The tester is supplied complete with heavy-duty plastic carrying case, electronic balance, beaker, cleaning cloth, cap, washer, scoop, steel pulverizing balls and cleaning brushes. Meets ASTM D4944 and AASHTO T217. Shipping Wt. 13 lbs. (5.9kg) Accuracy: Within 0.5% on most materials
Test Speed: 45 sec. to 3 min., depending on material
Gauge: Calibrated from 0-20% moisture based on wet weight
Balance: Electronic; 0-7 oz (0-200g) range; battery operated

Moisture Tester Reagent

Calcium carbide reagent for Speedy® Moisture Testers. Carton of 24-1 lb. (0.5kg) containers. Shipped via motor freight only. HAZARDOUS WARNING: Danger of explosion/fire may result if Moisture Testing Reagent is allowed to contact with moisture. Calcium carbide forms flammable acetylene gas when wet so must be kept sealed and dry. Provide adequate ventilation and use away from sparks and flame. U.S. shipping regulations require shipment by approved carriers. Contact Humboldt for international shipping regulations. Shipping wt. 26 lbs. (11.7kg)
