WP4C Dew Point Water Potential Meter

WP4C Dew Point Water Potential Meter

WP4CDew point water potential meter is used to quickly and accurately determine the water potential of various samples. The range is 0-300 MPa and the accuracy is 0.05MPa.

WP4CThe use of cold mirror dew point technology 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.

Main Features

versatility WP4CIt can measure the water potential of any porous material, such as apples, bricks, oil, and insect shells.

Easy to operate When 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 mode In precision mode, automatic checks are performed to ensure that the sample has reached equilibrium before displaying the final reading.

Reaching balance faster The Nickel Teflon coating used in the sample chamber is hydrophobic. Reducing the water absorption of the sample chamber means that equilibrium can be reached faster.

Fine tuning calibration WP4CSensors are durable and easy to clean. The instrument can be calibrated with a saturated salt solution (self prepared or ordered). The system algorithm can achieve better accuracy (± 0.05MPa 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
