Miller Soil Box, Large

Miller Soil Box, Large

Our Large Soil Box, also known as a large box, has a 270ml (270cm³) volume and is compatible with 4-Terminal Resistance Meters such as the Miller 400A, the Miller 400D and the Nilsson 400 Resistance Meters.

Miller Soil Boxes can be used for either the 4-electrode method (ASTM G57 Standard) or the 2-electrode methods (ASTM G187 or AASHTO T-288 Standards).

For the 2-electrode method, the two interior pins are removed which changes the multiplication factor from 1cm (for the 4-electrode method) to 0.67cm for the small soil box or 0.57cm for the large soil box. See this link for more details: ASTM G57 and AASHTO T-288 Stand

Features

• Plexiglas body with rounded corners for easy cleaning

• Stainless steel current distribution plates and removable brass pins (potential measurement pins)

Critical Dimensions (for 4-electrode method, i.e. the two interior pins are in use): The soil boxes are designed such that the cross-sectional area of the soil (or liquid) sample (A), with the soil box filled level, divided by the separation between the pins (L) is equal to 1 cm.

• Cross-sectional area = 4 cm x 3.2 cm = 12.8 cm²

• Pin separation = 12.8

Soil Box Example: M.C.Miller Factory Tap Water

Measured Resistance = 1.97 kΩ Resistivity Value = 1.97 kΩ x 1 cm = 1,970 Ω.cm [M.C. Water Conductivity = 1.0]

The dimensions of the soil box are critical for accurate measurement interpretation, allowing for direct expression of resistivity in ohm-centimeter without the need for additional calculations.

Stainless Steel Current Plates

Our soil resistivity measurement soil box is quick and easy to use for field and laboratory applications. Our soil resistivity measurement soil box measures soil and water samples quickly and accurately for field and laboratory use. It is compatible with multi-combination meters (MCM) or separate volt and ammeter setups for any testing situation.

The clear material of the soil box allows for easy cleaning and inspection of samples so you can keep your measurements intact. Rounded corners make it easy to handle and clean, stainless steel current plates for durability and accuracy. Check out our Chrome Plated Penetrometer for Soil Tests for more options in durable soil testing equipment. This means accurate measurement in ohm-centimeter (Ωcm).

Soil Box Materials

The soil boxes are made of high quality materials for durability and accuracy in soil resistivity testing. The main body of the soil box is typically made of clear plexiglass or strong resin, for easy cleaning and inspection of samples. The clear material also allows users to visually inspect the soil sample and ensure it is at the correct filled level for accurate measurement.

The current plates are usually made of stainless steel, for excellent conductivity and corrosion resistance. The potential pins are often made of brass, for good electrical conductivity and durability.

High quality materials ensure the soil boxes can withstand field and laboratory use, for reliable and accurate results. The rounded corners of the soil box also make it easy to clean and minimize the risk of damage during excavation and sample preparation.

The dimensions of the soil box are critical, the cross-sectional area of the soil box is designed to ensure the multiplication factor is correct. The soil box is designed to express measured resistivity in ohm-centimeter (Ωcm), a universal terminology.

Overall the materials used in the soil boxes are selected for accurate and reliable results in soil resistivity testing.

Technical Details and Measured Resistivity

Our soil resistivity measurement soil boxes come in different sizes to fit your testing needs. The large soil box is 1.50” x 8.75” x 1.25”, the small soil box is 1.16” x 4.39” x .94”. The cross-sectional area is critical for measurement, available in 1.11in² (7.2cm²) and 1.98in² (12.8cm²).Our soil resistivity measurement boxes meet the requirements of specific electrochemical methods outlined in industry standards such as ASTM G57, G187 and AASHTO T-288.

The multiplication factor is critical for calculation, available in 0.67 cm and 0.57 cm for accuracy. The filled level is designed for measurement, so you have a consistent basis for your results. This allows for better comparison and analysis of soil resistivity data.

Our soil resistivity measurement boxes keep your dimensions intact, so you get accurate and reliable results every time you use them. Corners make it easy to handle and clean, stainless steel current plates for durability and accuracy.

One of the key features of our measurement boxes is they measure ohm-centimeter (Ωcm). This is the unit of measurement for soil resistivity, so it’s critical for accurate readings. With our measurement boxes you can be sure your results are precise and dependable.

We know different testing needs require different box sizes. That’s why we offer two options: standard and compact. The standard measurement box is 25 cm deep, the compact is 15 cm deep. Both are 10 cm wide and long, so you have plenty of space to test various soils with a soil compaction tester. Additionally, for accurate soil testing results, consider using a Digital Soil Compaction Tester.

In addition to precise dimensions, our boxes are also built to last. Made from high quality materials they can withstand frequent use and handling without compromising accuracy. Current plates are corrosion resistant for long term reliability.

Our dimensions are also versatile in use. They can be used for laboratory and field testing, so you can test wherever you need to. Lightweight and sturdy they are easy to transport and set up on site.

Pins are key to the measurement. Our boxes have removable brass potential pins and current plates for repeatable dimensions. Resistivity is measured in ohm-centimeter (Ωcm) the industry standard.

These boxes are for use in excavation and construction projects to calculate soil resistivity with the formula: Resistivity = (ΔV between pins) / (ΔI). They are for testing soil, water or other electrolyte samples so they are versatile for ground testing and experiments.When testing you need reliable and accurate equipment. That’s where our resistivity boxes come in. They are designed for both laboratory and field testing so you can test wherever you need to.

One of the key features of these boxes is their lightweight and sturdy design. This makes them easy to transport and set up on site, saving you time and effort when setting up your test.

But what really sets our resistivity boxes apart is their pins. These pins are critical for accurate dimensions as they are the connection points between the equipment and the sample being tested. Our boxes for sale have removable brass potential pins and current plates for repeatable results every time.
