Open Pan Evaporimeter

Q: How do I use the Open Pan Evaporimeter to measure the evaporation rate?

A: To measure evaporation, fill the pan with water up to the recommended level and record the initial water level. After a set period, typically 24 hours, measure the remaining water. The difference indicates the amount evaporated, representing the daily evaporation rate.

Q: What are the main benefits of using this manually operated evaporimeter?

A: This evaporimeter provides highly accurate, reliable measurements (100% accuracy) without the need for external power or batteries. Its robust, weather-resistant construction and simple setup make it ideal for continuous outdoor usage.

Q: When is the best time to conduct evaporation measurements with this instrument?

A: Evaporation measurements are usually taken daily, ideally at the same time each day to ensure consistent data collection and accurate comparison of results over time.

Q: Where should I install the Open Pan Evaporimeter for effective results?

A: Install the pan in an open, shaded area on level ground, away from large obstacles or structures that could block wind flow or sunlight, as these factors can impact the accuracy of evaporation readings.

Q: What is the process for maintaining the Open Pan Evaporimeter?

A: Regularly clean the pan to prevent algae or sediment buildup and periodically inspect for any signs of wear or corrosion, especially after prolonged exposure to harsh weather. Maintenance is minimal due to the durable, non-electronic design.

Q: Can the evaporimeter be used for applications other than measuring water evaporation rates?

A: While it is specifically designed for measuring the rate of evaporation from free water surfaces, data collected can support agricultural planning, meteorological research, and water resource management activities.
