The AMS 59032 Pocket Penetrometer is a compact and reliable device that provides accuracy of soil strength. This spring-operated unit measures the compressive strength of soil in tons/sq. ft. or kg/sq. cm by pushing a 1/4in diameter loading piston into the soil to a depth of 0.25in. With its 6-1/4in size, it is convenient to carry and use in various settings.

The AMS 59032 Pocket Penetrometer is designed for ease of use and accuracy. The compressive load is indicated by reading a scale on the piston barrel, and a friction ring indicates the maximum reading. Made of high-quality anodized aluminum, this pocket penetrometer is durable and built to last.

For added convenience, the AMS 59032 Pocket Penetrometer comes with an Allen wrench and a plastic carrying case with a belt loop. This allows you to store, ensuring that it is always at hand when you need it. Additionally, an optional 1in-diameter adapter foot is available for use in very sensitive soils, providing versatility and adaptability to different soil conditions.

It is important to note that a pocket penetrometer is a requirement by OSHA on all excavation jobs. By investing in the AMS 59032 Pocket Penetrometer, you not only fulfill this requirement but also protect yourself from costly lawsuits and construction delays. Accurate measurement of soil strength is essential for ensuring safety and preventing accidents and determining penetration resistance.

In conclusion, the AMS 59032 Pocket Penetrometer is a reliable and essential for any excavation job. With its accuracy, durable construction, and convenient design, it is the perfect choice for professionals in the construction industry. Invest in the AMS 59032 Pocket Penetrometer today and ensure the safety and success of your excavation projects.

Overview of the AMS 59032 Pocket Penetrometer and Its Application in Soil Testing

The AMS 59032 Pocket Penetrometer is a vital tool in the field of geotechnical engineering and agriculture, offering a portable solution for assessing soil compaction and quality. This device provides immediate feedback on the soil's penetration resistance, which is crucial for determining the suitability of soil for various agricultural and construction purposes. This comprehensive overview will delve into the features, uses, and significance of the AMS Part Number 59032 Pocket Penetrometer in soil testing and food products.

Design and Features of the AMS 59032 Pocket Penetrometer

Construction and Materials:
Soil penetrometers are crafted with durability in mind, featuring a robust stainless steel body that resists wear and tear under field conditions. The penetrometer is equipped with a stainless steel plunger and a set of cones and stainless steel needles that are used to measure the penetration resistance of soil. The device's compact and lightweight design makes it easy to transport and use in various field settings.

Functional Components:
At the core of soil penetrometers are its precision components:
Cones and Needles: These are essential for piercing the soil and obtaining measurements. The penetrometer typically comes with a standard, stainless steel cone tip, which is used to evaluate firmer soil types.
Plunger: This component applies a consistent force to the cone or needle, driving it into the soil for penetration resistance. The depth of penetration resistance is then read directly from a scale engraved on the plunger, provided in lbs per square inch.

Application in Soil Testing

Soil Compaction Testing:
Soil compaction reduces the pore space within the soil, adversely affecting water infiltration, root growth, and ultimately, plant development. The AMS Part Number 59032 penetrometer is specifically designed to measure soil compaction by determining the penetration resistance of the soil. This is measured by the force required to push the cone into the soil to a specific depth.

Determining Quality:
Soil quality is critical for both agricultural productivity and construction stability. The penetrometer helps in assessing the soil's physical properties, including its density and consistency, which are indicative of its overall health and quality. This assessment is vital for farmers to determine the optimal times for planting and harvesting food products and for construction managers to evaluate land suitability.

Sample Testing in Field and Laboratory Settings:
While primarily a field-testing device, the AMS Part Number 59032 can also be used to prepare samples for further laboratory analysis. By providing initial measurements of soil consistency and compaction, field personnel can select representative soil samples for more detailed testing under controlled conditions.

Operation and Process

Using the Device:
To use the AMS Part Number 59032 Pocket Penetrometer, the user places the cone tip against the soil surface and slowly presses the device vertically into the soil. The scale on the plunger allows the user to read the penetration resistance directly, typically in terms of pounds per inch, which indicates the soil's compaction level.

The soil penetrometers provide readings directly from the scale on the plunger for penetration resistance, offering immediate insights into the soil's condition. These measurements are crucial and depends on consistent application of force and proper alignment of the device during testing.

Advantages and Limitations

Efficiency and Portability:
One of the primary advantages of soil penetrometers are its efficiency and ease of use, which make it an indispensable tool in field applications. Its portability allows users to conduct on-site assessments of soil compaction without the need for bulky equipment.

Soil penetrometers are capable of measuring a wide range of soil types, from loose sands to harder clay soils, making it versatile across different environments and conditions.

While highly useful for preliminary assessments, the AMS Part Number 59032 penetrometer does have limitations. It may not provide the depth of data required for certain complex geotechnical evaluations, which would necessitate more comprehensive testing methodologies.

Maintenance and Care

To ensure longevity and accurate performance, regular maintenance of the AMS Part Number 59032 penetrometer is essential. This includes cleaning the cone and needles to remove any residual soil and storing the device in a protective case to avoid damage. Periodic calibration may also be required


The AMS Part Number 59032 Pocket Penetrometer is a crucial tool for professionals in agriculture, construction, and environmental science. It provides a quick and reliable method for assessing soil compaction and quality, directly influencing crop productivity and construction project outcomes. By facilitating immediate soil evaluations, this device plays a pivotal role in efficient land management and precise agricultural planning, reinforcing its indispensability in field operations.
