The evaporation sensor supports evaporation measurement from 0 to 200mm, can accurately capture water surface changes, and is suitable for water treatment, environmental protection, agricultural irrigation, meteorological monitoring, liquid level control and other fields.

Features

• Evaporation sensor adopts a double-layer stainless steel design, which effectively prevents the evaporation error caused by sunlight exposure and makes the measurement result more accurate.
• The evaporation sensor adopts the pressure measurement principle, measures the weight change of the liquid in the evaporating dish by weighing, and then calculates the liquid level to obtain the evaporation.
• Its 304 stainless steel shell is corrosion-resistant and has a beautiful appearance, which can effectively ensure the service life of the sensor.
• The evaporation sensor has the advantages of high measurement accuracy, wide range, high sensitivity and long-term stability.
• This sensor adopts the wiring method of bottom outlet, which reduces the exposed wires to avoid line failures and is easy to install.

Tips: What is an evaporation sensor?

The evaporation sensor is a device used to measure the evaporation rate of the surface of water or other liquids. It calculates the rate of water evaporation from the surface to the air by monitoring factors such as humidity, temperature, and air pressure in the environment, usually in units of mm/hour or mm/day. The sensor is widely used in agriculture (such as monitoring irrigation needs), water resources management, meteorological research and other fields to help optimize water resource use and environmental monitoring.
