描述
Product Overview
Modbus evaporation transmitter is an evaporation measurement instrument based on pressure measurement principle, which can be widely used in meteorological observation, plant cultivation, seed cultivation, agriculture and forestry, geological survey, scientific research and other fields.
Product Features
- High measurement accuracy: Using high-precision weighing principle to measure the weight change of liquid in the evaporating dish, the measurement accuracy can reach ± 1% FS.
- Strong anti-interference ability: The unique double-layer stainless steel design can effectively isolate external interference, making measurement results more accurate.
- Strong adaptability: able to observe normally under wind, waves, and rainy weather conditions without losing accuracy.
- Stable performance: Digital sensor, no temperature drift or time drift, long-term stable performance.
- Easy to install: The bottom outlet wiring method reduces exposed wires, avoids line faults, and is easy to install.
- Multiple power supply methods: Supports wide DC power supply 10-30VDC power supply.
