XA-204 Intelligent Precipitation and Dust Reduction Automatic Sampler
1、 Execution standards:
GB13580. (1-13) -92 "Sampling and Analysis Methods for Atmospheric Precipitation"
HJ/T174-2005 "Technical Requirements and Testing Methods for Rainfall Automatic Samplers"
2、 Purpose:
This instrument is an automatic sampling device that replaces manual collection of dry sediment, acid rain, and snowfall samples. Mainly used for environmental monitoring, meteorological research and other units to quantitatively collect rain and snow samples for acid rain quantitative component analysis. Equipped with an automatic rainfall sensor, it can automatically accumulate rainfall.
3、 Performance characteristics:
Intelligent design, simple operation, novel overall structural design, reliable operation, simple operation, non-volatile sample collection, and no repeated pollution. Adopting comb shaped sensors with constant temperature heating function, snow melting ability, automatic judgment of rainfall situation, determining the working status of the instrument, effectively preventing bird droppings, fog, dew and other misoperations, strong anti-interference ability, high sensitivity, reliability and durability.The sampling system adopts a dual arm four-bar linkage structure to drive the gear to rotate, with reliable operation, good sealing of the sampling bucket, and convenient sampling.
Equipped with a real-time clock and 1000 sets of data storage, it is convenient for users to query parameters such as the start and end time of rainfall and rainfall amount. Sampling data can also be printed through a micro printer. The instrument is equipped with a rechargeable battery for storing data during AC power outages, automatically restoring sampling upon incoming calls, and allowing users to check the power outage time. Different working modes can be set to automatically and continuously collect and save samples such as snowfall, rainfall, and dust. Equipped with three rain polyethylene collectors (sampling buckets).
