Model Overview

Automatic precipitation collection and online analysis systemNMO191There are different models to choose from, providing different quantities of sample collection bottles and collection methods.

measuring principle

After the precipitation begins, the precipitation sensor emits a pulse signal and opens the funnel to collect samples. The way to open the funnel is to move the lid horizontally outward, which can prevent power from interfering with the sampling process. The precipitation in the funnel first flows into the diversion funnel and is then divided into two parts, one entering the sampling system and the other entering the measurement room. Measure precipitation indoorsPHValue and conductivity. After the precipitation stops, the precipitation sensor sends a signal to drive the motor to close the collection funnel. The heating system for the precipitation chamber or sampling bottle is optional and providesKSConstant temperature model.

Technical features

Continuous measurementPHValue and conductivity are used to obtain the instantaneous values of the quantity and acidity of dissolved substances. The synchronous measurement of two parameters can effectively control the quality of measurement results and estimate the amount of free acids in water. And these quantities are closely related to the temporal development of precipitation events. Observation of precipitation intensity and quantity helps to gain a deeper understanding of the physical mechanisms underlying the cleaning process. yesKSThe model has an automatic cooling defrosting device installed at the bottom of the collector. By using a plate type evaporative ventilation cooling device, the cooling temperature can be maintained at a certain level in high-temperature environments4°C(Range of fluctuation ±2°C).

And the sampling system can choose mixed sampling; Automatic multi day timed sampling (automatically rotating one sampling bottle per day); Multi week timed sampling (automatically rotating one sampling bottle per week); Even automatically sampling for each precipitation event (with one sampling bottle automatically rotating for each precipitation event).

The sampling principle for precipitation events is as follows: the system uses automatic rotation sampling bottles based on precipitation events, and each new precipitation event corresponds to a new sampling bottle. When the sampling volume of a single bottle of rainwater exceeds1Automatically overflow when rising. When the user needs to replace all sample bottles, the instrument will issue warnings and warning signals. We offer two sets (each set)2Bottle, or8Bottle or Gundam16The sampling bottle system is available for customers to rotate and use.
