DroughtSpotter - Spot Irrigation and Transpiration Rates System
From Sensors
The DroughtSpotter records the loss of weight of every pot with high precision and computes transpiration dynamics and water use efficiency for every single plant. Irrigation activities are automated with high accuracy and reliability – even during the weekends!

Products Details
- Assess transpiration rates of plants fully automatically and in high-throughput
- Assess water use efficiency fully automatically
- Design and automate all irrigation activities in high Precision and reliability
Hence no more manual weighing to assess the transpiration rates of your plants. DroughtSpotter controls your experiments with high precision and reliability even during the weekends.
A DroughtSpotter table contains either 12 or 24 scales. Tables can be linked for high throughput. Each scale is equipped with a height adjustable irrigation tube for pot heights up to 500 mm. DroughtSpotter can be used in climate chambers, labs and grenhouses.
Irrigation modules & water modes:
Design the irrigation schedule of each individual pot with our irrigation module and automate the irrigation of your experiments. The irrigation module will take care of your dry-down- or recovering experiments with high reproducibility and reliability.
Drought Spotting, phenotyping for water saving traits
Using the high measuring frequency of the DroughtSpotter enables you to measure absolute differences in transpiration and its dynamics over the course of the day. In this study Vadez et al. 2015 assessed transpiration rates of two different Pearl Millet genotypes (VPD at noon noted in the graph). One genotype (PRLT) shows significantly less transpiration at high VPD. This “water saving trait” is of a benefit in a drought scenario and leads to higher yield. Please note that leaf area in this experiment was assessed with the PlantEye.
Software
Design, control and track your experiments anywhere in the world. All data is stored locally on the system and processed on a server that comes with the gravimetric systems.
