System Overview

The ZJC - IX Full Performance Precipitation Automatic Monitoring System is a product developed by Zhejiang Hengda Instrument Co., Ltd. based on years of accumulated technical and application experience in precipitation sampling and monitoring. It can automatically collect precipitation, monitor the amount of rainfall in rainwater pH、 Conductivity, water temperature F^-、Cl^-、SO₄^2-、NO₃^-、NH₄⁺、Na⁺、K⁺、Mg²⁺、Ca²⁺The product has twelve parameters and can be extended to other monitoring projects for anions and cations.

This product can be widely used in environmental monitoring departments, meteorological monitoring departments, agricultural and forestry monitoring departments, and research institutes. It can replace traditional manual monitoring to achieve fully automated daily monitoring, analyze the causes of acid rain, and predict the impact of acid rain.

2 Main functions

1Automatic rainfall sampling functionThe system automatically collects precipitation samples through an outdoor precipitation sampler;

2Automatic sample retention functionWhen analyzing rainwater samples, the system can synchronously collect a portion of the samples and store them in a refrigerated container;

3Pre analysis processing functionImplement automatic filtration of rainwater samples before analysis, using the same filtration method as laboratory methods;

4Automatic rainfall analysis function,The system automatically analyzes the processed samples through an indoor analyzer;

5Automatic cleaning function，Regular automatic cleaning can eliminate the cross influence of water samples and the replacement cycle of consumables;

6Pipeline algae removal function，Using green non-toxic algae removal agent to automatically remove algae from pipelines, avoiding the growth of algae in pipelines;

7Automatic calibration function, achievableAutomatic calibration of pH electrode;

8Operation protection functionIt can automatically preheat when not in operation for a long time to ensure stable performance;

9communication, support3G/4G/5GMultiple communication methods, combined with a high-performance automatic precipitation monitoring platform, can achieve remote data transmission and supervision of the system.

3 Main Features

1This system adopts well-known brands of anion and cation detection equipment, specially designed to meet the needs of users for anion and cation detection in rainwater;

2Adopting the same injection method as the laboratory to ensure consistency with laboratory analysis;

3The system can continuously and automatically regenerateExemption from preparation of inhibitory solutionofWorry, reducefinishBaseline noise and drift, easy to operate；

4The system only needs to regularly replenish pure water to generate the required concentration of rinsing solution online,reduceThe systemNoise andBaseline background, improve system detection limit and method reproducibility;

5Controlled by chameleon software, it has the characteristics of simple operation, fast startup, reliable and stable performance, etc;

6The pipeline components are made of inert and non adsorbent materials, which will not change the ion composition of the rainwater sample;

7Professional rainwaterpHConductivity electrodes have excellent stability for measuring rainwater;

8The outdoor part of the system hasIP55Protection level, applicable toExtremely cold and plateau regions.
