Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang DICKEY-JOHN dari 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?
