  • Product Introduction
  • 1. Introduction to the instrument


    The instrument is equipped with sensors such as rain sensor, rain gauge, PH meter, electrical conductivity, temperature, etc., which can automatically and continuously collect, save and monitor atmospheric precipitation, collect dust samples, and realize all-weather and online monitoring of precipitation indicators, which greatly reduces the operator's workload. It can be widely used in environmental protection, health, labor, safety supervision, military, scientific research, education and other fields.


    2. Technical characteristics


    1. Equipped with two independent parallel intelligent comb rain detectors, which can automatically judge the rainfall and determine the working state of the instrument to prevent misoperation;

    2. Equipped with SL-3 standard rain gauge;

    3. It can real-time and intelligently complete pH value, conductivity value, temperature measurement and automatic compensation, and realize automatic range conversion within the measurement range;

    4. The sensor adopts composite pH electrode and high buffer U -shaped flow cell, which improves the stability of pH measurement;

    5. It has the function of automatically protecting pH electrode and conductivity electrode;

    6. The famous refrigerator is adopted to realize the refrigerated storage of samples at (4 ± 1) ℃;

    7. The switch cover adopts a double-arm four-link structure, with stable action and flexible sealing to ensure that the samples in the sampling barrel are free of contamination;

    8. It has dual functions of precipitation, dust collection and preservation;

    9. Automatically record the start and end time of precipitation, the number of precipitations, the total time of precipitation, the amount of rainfall, PH value and conductivity value , and the storage and query function of a huge 8,000 rainfall event data;

    10. With RS232 interface, it is convenient for data dumping;

    11. With instrument fault self-check, power-down data protection and clock function;

    12. Optional GSM module for remote wireless data acquisition and control.
