Mini Evaporator After hours, measure the remaining water volume with a measuring cup; the amount of water reduced is the evaporation volume. Centimeters. A small evaporimeter is an instrument used to measure the amount of water evaporated from the atmosphere over a certain time interval. The product is mainly made of brass plates. It features a compact structure, attractive design, durability, and practicality, making it suitable for hydrological and meteorological stations and other relevant departments. 2 Dimensions:φ340mm×282mm Quantity: 1.70 kgType : Brand Model: ZZ-1 Dimension and Shape: 20*10） （KgProduct Application:
Small evaporators are 20 cm in diameter and 10 cm in height.MetalOvalBasinThe pot rim is shaped like a blade. To prevent birds and animals from drinking, a metal wire mesh ring in the shape of a bell is placed on the upper part of the pot opening. When measuring, place...InstrumentPlace on the shelf, with the opening 70 cm from the ground, add a measured amount of fresh water daily, every 24HourAfterward, measure the remaining water volume with a measuring cup; the reduced amount of water is the evaporation volume. Add a 2-centimeter deep water layer to the evaporation dish each day, and pour the excess water into the measuring cup at night to measure the remaining water depth. Subtract the remaining water depth from 20 centimeters to determine the day's evaporation volume. If it rains on the same day, subtract the day's rainfall from the excess water. This is why the diameter and ground height of the evaporation dish must match those of the rain gauge; otherwise, they cannot be simply subtracted. The small evaporation pan is an instrument used to measure the evaporation of water in the atmosphere over a specific time interval. The main components of this product are made of brass sheets. It features a compact structure, attractive design, durability, and practicality, making it suitable for hydrological and meteorological stations and other relevant departments.
Installation & Use:
Installation - The evaporating dish should be placed in an open, flat area exposed to sunlight throughout the day, with the rim positioned horizontally, approximately 700mm from the ground.Millimeters high, a wooden post can be inserted and nailed to hold a shelf or a brick pedestal can be built, securely placing the evaporating dish on top.
2. Use — Observe once daily at the designated time, using a measuring cup (diameter 200) from the previous daymm rainfall gauge measuring cylinder filled with water20millimeters, injected into the dish, after24After an hour, pour the remaining water in the dish back into the measuring cup at the specified observation time today, measure the lost amount, which will be today's evaporation volume. Refill with fresh water and measure again in the cup after observation.20Millimeters of water are added to the evaporating dish to maintain20Millimeters of water.
If rain falls into the container, the precipitation amount should be deducted from the recorded rainfall to obtain the actual evaporation volume for this occasion.
If it's the freezing season and there's ice in the dish, the weighing method should be used. Method:——Fill the dish with 20After 1mm of clean water, weigh its weight on a balance (in grams), and then24After an hour, weigh it again, and the difference in weight is the actual evaporation amount (in millimeters).
