The sap flow measuring sensor for petiole and thin stems of fruits and flowers on Unipos website Sap Flow Sensors SF-4M / SF-5M Page has been added.
The Sap Flow Sensors SF type is a sensor for measuring and monitoring the flow of sap in the petiole, stem, and pedicel (diameter less than 10 mm) that are the passages for water and nutrients of plants. This sensor does not hurt the plant because it is a cylinder type that wraps the stem from the outside, not a method that penetrates inside the stem or petiole.
Inside the cylinder, there are small heaters and temperature sensors above and below the heater. By supplying electric power to a small heater, a part of the stem is heated about 2-3 degrees from the surroundings, and the output signal for obtaining the sap flow rate and transpiration rate is measured, which is useful for data analysis.
In addition to the above products, when you contact us about measuring instruments such as environmental research and monitoring by edaphic scientific, please let us know your desired product name.
* Notice * (Added in October 2020)
Production of Sap Flow Sensors SF-4M / SF-5M is currently suspended for about half a year due to the influence of the new coronavirus (as of October 2020).
If you wish, please let us know the following items so that we can guide you to alternatives.
– About the species to be measured
– Diameter of stem or trunk to be measured
We will inform you on this page when the prospect of resale is established.
* Notice * (Added in October 2022)Due to the suspension of production due to the influence of the new coronavirus, we have postponed the announcement from around October 2020, but we are pleased to inform you that production has resumed. The delivery time depends on the time of request, but it is 5-10 weeks (4-8 weeks + 1-2 weeks). |
