  • Heat Ratio Method Sap Flow Products

    For the measurement of sap flow or transpiration in plants

    Sap Flow Meter


    A self contained, stand-alone instrument for the measurement of sap flow or transpiration in plants. Utilising the Heat Ratio Method (HRM) principle the Sap Flow Meter is able to measure high, low, reverse and zero flow rates in both small woody stems and roots as well as large trees.

  • Heat Field Deformation Sap Flow Products

    For the measurement of sap flow or transpiration in plants

    Heat Field Deformation Meter


    The Heat Field Deformation (HFD) technique is ideally suited to sap flow research projects that require the measurement of extended radial sap flow profiles to accurately map hydraulic architecture of trees. Similar to the HRM sap flow sensor the HFD sensor can measure high sap flow rates as well as low to zero and reverse sap flow.

  • Plant Transpiration Products

    Measures transpiration in small or large plants

    WSM1 Weigh Scale Meter


    The WSM1 Weigh Scale Meter continously measures transpiration in small or large plants. Plants are placed on the scale and the weight is logged continously at user defined intervals. The amount of weight lost over time is a direct measure of water loss from the plant.
