PARIO Plus Soil Particle Size Automatic Analyzer

PARIO Plus Soil Particle Size Automatic AnalyzerCalculate the particle size distribution based on Stokes' law, with a measurement range of 63~2 μ m. The measurement method of PARIO is based on mature hydrometer or straw methods, using pressure sensors to continuously record pressure and temperature changes at specific locations in soil suspension at 10 second intervals, to obtain a complete soil particle size distribution curve.

Product Introduction

PARIO Plus Soil Particle Size Automatic AnalyzerOn the basis of PARIO, further improvements have been made, resulting in significant improvements in measurement accuracy and efficiency.

The revolutionary soil particle size analysis equipment PARIO developed by METER was launched in 2017. Compared with the traditional particle size analysis method PARIO, it shows an absolute advantage. The traditional hydrometer method (or straw method) takes 24 hours to manually operate, which is time-consuming, labor-intensive, and prone to errors. The laser particle size analyzer method is expensive, time-consuming, and has methodological deviations. After setting up PARIOPlus, the entire process will be automatically measured, and only the valve needs to be manually opened at the end of the measurement.

The measurement time has been shortened to only 2.5 hours, with an estimation error as low as ± 0.5%. PARIO Plus frees scientists' hands from complex experiments and allows them to fully devote themselves to the study of scientific problems.

Measuring principle

Calculate the particle size distribution based on Stokes' law, with a measurement range of 63~2 μ m. The measurement method of PARIO is based on mature hydrometer or straw methods, using pressure sensors to continuously record pressure and temperature changes at specific locations in soil suspension at 10 second intervals, to obtain a complete soil particle size distribution curve. PARIO Plus uses the more precise "Extended Integral Suspension Pressure Method" (ISP+) (Durner et al., 2017). In addition, PARIO based on Stokes' law does not require transfer function correction of soil properties, while almost any other automatic measurement method requires such correction, such as laser diffraction or image analysis.

Main Features

After setting up the fast measurement speed, the instrument only needs 2.5 hours to run.

The precise estimation error of the measurement method is as low as ± 0.5%, which is lower than any traditional particle size analysis method.

Automatic independent operation of PARIO allows for unmanned and automated operation, requiring only manual valve opening at the end of the experiment. Avoid manual reading and calculation errors.

Obtaining high-precision continuous particle size distribution curves is different from traditional methods that measure a few discrete time points. PARIO performs automatic measurements every 10 seconds and continuously records the pressure and temperature changes of the suspension.

The measurement process is undisturbed and does not require the insertion of a liquid density meter or the use of a pipette for sampling the suspension, thereby reducing disturbance to settlement.

Calculate the particle size distribution based on classical principles and Stokes' law, matching the traditional experimental preparation workflow.

√ Directly measure the clay content to obtain

√ Automatically calculate particle size distribution based on temperature synthesis

√ In order to save you more time, PARIO adopts a simple and easy-to-use integrated software solution, which easily realizes data query, visualization operation, data calculation and export.
