Overview

The WP4C dew point water potential meter is an upgraded product of WP4-T. Used for rapid and accurate determination of water potential of various samples. The range is -0.1 to -300 MPa, with an accuracy of 0.05 MPa. The WP4C adopts cold mirror dew point technology, which is becoming the standard dew point water potential measurement principle in the industry. The water potential of a sample has a certain functional relationship with its water vapor pressure at equilibrium in a specific space. WP4C maintains a temperature equilibrium state by measuring the dew point temperature of the air in a closed sample chamber, and then calculating the sample water potential based on an internal function.

Product Details

Main Features

  • versatilityWP4C can measure the water potential of any porous material, such as apples, bricks, oil, and insect shells.

  • \\\\Easy to operateWhen measuring water potential, simply put the sample into a sample cup (diameter 4cm, height 1cm), place it in the sample chamber drawer, and push it into the detection area. The reading can be obtained in 5 minutes

  • Precision modeIf the measurement process is too fast, the results may not be accurate. The new WP4C will be checked in precision mode to ensure that the sample has reached equilibrium before displaying the final reading.

  • Reaching balance fasterThe newly adopted nickel Teflon coating in the WP4C sample room has hydrophobicity. Reducing the water absorption of the sample chamber means that equilibrium can be reached faster.

  • Fine tuning calibrationThe WP4C sensor is durable and easy to clean. The instrument can be calibrated with a saturated salt solution (self prepared or ordered). The new algorithm can achieve better accuracy (± 0.05 MPa or less) during fine-tuning calibration.


Main applications

  • Detecting leaf and soil water potential characteristics

  • Measure the water potential of samples in the seed zone, rhizosphere zone, and under cover

  • Monitoring changes in water potential during bioremediation processes

  • Measuring the dependence of seed germination process on water potential

  • Measure the general water release curve

  • Monitoring the changes in water potential of seed filling media

  • Measure the moisture relationship of mixed fertilizers
