Frequently Asked Questions

What is the difference between gravimetric and volumetric soil moisture measurement?

Gravimetric soil moisture measures water mass relative to dry soil mass (expressed as % by weight), while volumetric soil moisture measures water volume relative to soil bulk volume (expressed as % by volume). The PAL-Soil determines both parameters simultaneously.

How much sample material is required for measurement?

For gravimetric analysis: 15 g glycerin and 15 g soil specimen. For volumetric analysis: 30 mL glycerin and 50 mL soil specimen. Alternative gravimetric measurements require only 1–2 drops of sample.

Does the device provide temperature compensation?

Yes, the PAL-Soil includes automatic temperature compensation across the 10–40°C range, ensuring accurate readings regardless of ambient temperature variations.

What is the measurement time for a single determination?

One complete measurement cycle requires 10 minutes, significantly reducing analysis time compared to conventional gravimetric or oven-drying methodologies.

Is the PAL-Soil suitable for field use?

Yes. The device's IP65 ingress protection rating (dust-proof and water-resistant) and compact handheld design make it suitable for both laboratory and field-based soil moisture assessment.

What standard does the PAL-Soil conform to?

The device complies with ISO 16586:2003 (Soil quality – Determination of soil water content on a volume fraction basis as a volumetric fraction based on known dry bulk density – Gravimetric method).
