PAL-Soil

This refractometer measures the moisture level of soil by testing the change in the refractive index of glycerin after it absorbs the water in the sample soil.

Atago PAL-Soil Soil Moisture Meter 0 to 200%

Highly accurate moisture level readings achieved by utilizing glycerin’s water absorption capabilities

Features:

  • Volumetric and Gravimetric measurement methods
  • Great for use in the lab or the field
  • Can be washed under running water without harming the instrument
  • Comes complete with:
    • AAA alkaline batteries
    • Filter paper
    • Re-sealable plastic storage bags
    • Beaker
    • Plastic tweezers
    • Plastic spoon

The Atago PAL-Soil meter is designed specifically to measure the moisture content of soil. It can be measured in two different ways using a Volumetric or a Gravimetric measurement method.

Both methods provide highly accurate results that previously were only available by baking the soil and noting the changed mass. This meter provides a faster and simpler way to determine soil moisture levels.

Test Procedure:

  1. (Gravimetric Measurement) Measure out an equal amount each of soil and glycerin. (Volumetric Measurement) (1.) Measure out 50ml of soil using a sand pouring cylinder or soil sampler. (2.) Measure out 30ml of glycerin and place it in a re-sealable bag.
  2. Mix the soil and glycerin thoroughly (to ensure the glycerin has soaked up all of the water).
  3. Place filter paper on the prism and place the soil-glycerin mixture on top.
  4. Press the START key.
  5. Measurement value is displayed in 3 seconds.

Applications:

- Construction

- Irrigation

- Compost production

- Drainage planning

As the glycerin absorbs the water its refractive index changes slightly. This refractometer is designed to measure those changes and determine the moisture content in a highly accurate way. When testing is completed this meter can be safely rinsed off under a running faucet.

Atago PAL refractometers are known for their fast response time and highly accurate results. This meter includes the added bonus of automatic temperature compensation, which increases the temperature range which accurate testing can be done in.
