Water Stress Meter
Infrared monitoring tool to identify plant water stress.
Benefits :
– Quick, convenient in-field tool to accurately measure leaf surface temperature.
– A practical monitoring tool to adjust crop water supply for optimum production.
Instructions :
• Press the trigger to turn on the meter. Point the Water Stress Meter directly at a white sheet of paper (from around 30 cm distance) and press the trigger to record the “ambient” temperature.
• Repeat process to take the temperature of the plant leaf surface. Beam can be aimed at individual plants, or into a full canopy. See Important section for required testing conditions.
• Take multiple readings and then use these to calculate the average crop temperature.
• Calculate the temperature differential between the ambient temperature and the crop temperature.
• If a crop is water stressed, it will be as hot as or hotter than the ambient temperature.
• If a crop has sufficient water, it should be cooler than the ambient temperature (due to evaporative cooling via transpiration).
Important :
• Plant leaf surface should be dry.
• Take readings during peak sunlight hours, in low wind conditions.
• If air temperature is much cooler than normal, water stress may not be reliably detected.
• Keep the sun behind you when taking readings.
• Avoid the beam measuring surrounding objects, e.g., soil, sky.
• Do not test immediately after watering, as an
inaccurate water stress level may be identified.
STORAGE & Handling :
• Do not point the laser directly at eye or indirectly off reflective surfaces.
• Do not use near explosive gas, steam or dust.
• Store out of sunlight. Do not store on or near hot objects.
