Product details
WH-NH ammonia concentration meterIt is a new product developed based on the principle of vibration by introducing advanced production technology from Canada. The product design adopts plug-in installation, which is widely used for ammonia concentration detection in pipelines, open tank containers, and closed tank containers. It is well applied in ammonia preparation, ammonia incoming material detection, ammonia recovery and other processes.
The concentration of ammonia water directly depends on the vibration frequency received by the sensor inserted into the ammonia water. The sensor is equipped with a built-in temperature sensor to provide temperature compensation.
