QT-1020 series evaporation station

Product Details

The Z-type water surface evaporation station is an instrument used to observe the regularity of water surface evaporation in different time periods. Manufactured in accordance with the requirements of the Standard No. SD265-88 of the Ministry of Water Resources of the People's Republic of China for the Standard for Observation of Water Surface Evaporation. It can be used directly with a Φ618 mm evaporation bucket or a 20 m2 standard evaporation pond to monitor the water evaporation. Its measurement accuracy and stability are far superior to ultrasonic and other types of water surface evaporation sensors, suitable for different regions and various environmental conditions.
