HYPROP 2 Laboratory Soil Unsaturated Hydraulic Conductivity Measuring Instrument

HYPROP 2 Laboratory Soil Unsaturated Hydraulic Conductivity Measuring InstrumentImproved the measurement efficiency and quality of soil moisture release curve. HYPROP 2 can generate soil moisture characteristic curves within the wet end range in just a few days instead of months, and this process is automated.

Product Introduction

The traditional method of measuring soil moisture release curve requires responsible operations, takes a long time, and may not be able to obtain key data points. The emergence of HYPROP 2 greatly improves the measurement efficiency and quality of soil moisture release curves. HYPROP 2 can generate soil moisture characteristic curves within the wet end range in just a few days instead of months, and this process is automated. If used in conjunction with WP4C, which can measure dry soil water potential, the soil moisture characteristic curve at the dry end can also be obtained, thus obtaining a complete curve.

Apart from thisHYPROP 2 Laboratory Soil Unsaturated Hydraulic Conductivity Measuring InstrumentIt can also be used to measure the unsaturated hydraulic conductivity of undisturbed soil in a 250mL soil ring. When used together with KSAT, hydraulic conductivity curves of any soil type can be obtained.

Measuring principle

HYPROP 2 monitors soil water potential through micro tensiometers installed in two locations. The entire measuring device is placed on a balance, and the soil water potential and sample weight are recorded over time. The soil moisture content is calculated based on the sample weight, and a water potential change chart is plotted as the moisture content changes. More than 100 data points can be obtained within the range of 0 to -100kPa, and higher resolution and richer information cannot be compared to traditional methods.

Product Features

√Directly calculate the available water content of plants

√Accurate and reliable, time-saving and labor-saving, easy to operate

√Simultaneously measure water retention function and hydraulic conductivity

√High water retention, especially when approaching saturation

√Hydraulic characteristics are derived from a large amount of measurement data

√Accurately and reliably obtaining unsaturated hydraulic conductivity, independent of the assumed model

√The measurement range of the tension meter exceeds the typical cavity point, as low as -240kPa √. The tension meter is inverted in the soil sample (not affected by evaporation and has no effect on the tension meter rod)

√After reaching the void stage, the water loss of the tension meter was reduced
