DICKEY-JOHN

DICKEY-JOHN, founded in the United States in 1966, is a manufacturer of instrumentation for agricultural and industrial moisture measurement and soil compaction testing. The company's product line centers on grain moisture testers, soil moisture meters, and soil penetrometers, serving applications in crop storage, food processing, and geotechnical assessment. DICKEY-JOHN equipment is designed to provide repeatable, quantitative readings under field and laboratory conditions. Grain moisture testers, such as the GAC series and MINI GAC models, operate on capacitance-based or near-infrared sensing principles, with sample sizes typically 250 g and moisture measurement ranges from 5% to 45% for common grains. These units include features like automatic temperature compensation, data logging, and compatibility with vehicle power adapters for mobile use. Soil penetrometers, including analog models with manual operation and plunger lengths up to 30 inches, measure soil compaction resistance in pounds per square inch (psi) or kilopascals (kPa), using interchangeable tips (e.g., 1/2-inch and 3/4-inch diameters) to accommodate different soil types. The instruments are built to withstand high-humidity environments, with operating humidity ratings up to 95% non-condensing. 3G Electric supplies DICKEY-JOHN moisture meters and soil testers globally, offering multiple SKUs that cover benchtop and handheld configurations. The product range includes the GAC500XT, GAC2100AGZ, MINI GAC, and analog penetrometer models, each with specific measurement ranges and accessories such as carrying cases and power adapters. For procurement specialists and maintenance managers, DICKEY-JOHN equipment provides a standardized method for verifying moisture content in grains and assessing soil compaction, which are critical parameters for quality control, storage optimization, and crop yield management. The instruments are supported by manufacturer calibration procedures and replacement parts availability through 3G Electric's logistics network.

Frequently asked questions

Common questions about DICKEY-JOHN from 3G Electric.

What is the moisture measurement range of DICKEY-JOHN grain moisture testers like the GAC500XT?

The GAC500XT grain moisture tester has a moisture measurement range of 5% minimum to 45% maximum, with a sample size of 250 g. This range covers common grains such as corn, wheat, soybeans, and rice. The instrument uses capacitance-based sensing and includes automatic temperature compensation to maintain accuracy across ambient conditions. For specific crop calibrations, refer to the manufacturer's lookup tables.

How does the DICKEY-JOHN analog soil penetrometer measure soil compaction?

The analog soil penetrometer, model 155850003ASG1, measures soil compaction resistance using a manual plunger with a 30-inch length and interchangeable tips (1/2-inch and 3/4-inch widths). The operator pushes the plunger into the soil at a constant rate, and the analog gauge displays resistance in psi or kPa. This provides a direct reading of compaction layers, which is useful for assessing root penetration potential and soil management decisions.

What accessories are included with DICKEY-JOHN handheld moisture testers like the MINI GAC?

The MINI GAC handheld grain moisture tester (e.g., model MINIGAC1PSG4) includes a carrying case for portability and protection. Some models also come with a vehicle power adapter for field use. The unit operates on batteries or external power, with a maximum operating humidity of 95%. The carrying case typically holds the tester, sample cup, and calibration tools.

Can DICKEY-JOHN moisture testers be used for soil moisture measurement?

Yes, DICKEY-JOHN offers benchtop and handheld moisture meters that are specified for both grain and soil testing. For example, the GAC500XT and MINI GAC models are listed for soil moisture measurement, with the same 250 g sample size and 5% to 45% moisture range. However, soil samples may require different preparation (e.g., drying or sieving) to ensure accurate readings, and calibration curves for soil types should be verified with the manufacturer.

What is the accuracy specification for DICKEY-JOHN grain moisture testers?

The moisture accuracy for DICKEY-JOHN grain moisture testers, such as model 467890010SG12, is ±0.5% under controlled conditions. This accuracy applies within the specified moisture range (8% to 32% for that model) and with proper sample preparation. Factors like sample temperature, grain variety, and foreign material can affect readings, so regular calibration checks are recommended.

Does 3G Electric supply DICKEY-JOHN products?
