What It Is

The Dickey-john 155850003 is a soil compaction tester built for agricultural and turf professionals who need to measure soil density in the field. It functions as a penetrometer that indicates resistance levels to help assess root-zone conditions.

What It Replaces

This tool replaces manual probing or guesswork when evaluating compaction layers before tillage or aeration. The upgrade is worthwhile when consistent, repeatable readings are required to guide equipment settings or management decisions across multiple sites.

Installation And Common Issues

The unit arrives ready to use with two interchangeable tips and an instruction sheet; no assembly or calibration is needed before the first test. Common issues include tip wear in abrasive soils and difficulty penetrating extremely hard or rocky ground without applying excessive force.

Questions about this item

Which tips are included with the 155850003 penetrometer for different soil conditions?

The tester ships with two interchangeable tips so you can select the appropriate profile for the soil type you are testing.

What is the correct way to insert the penetrometer so the reading is accurate?

Hold the gauge vertically and push the tip straight into the ground at a steady speed; angling the tool or driving it too fast gives falsely high compaction values.

How often should the pressure gauge on this compaction tester be recalibrated?

The manufacturer recommends checking calibration once per year or after any hard impact to maintain reliable readings.
