1. The instrument control adopts an embedded system with strong intelligent sampling capability. According to user sampling requirements, water samples can be collected using sampling methods such as equal time, equal amount, variable time interval, variable interval, or customer specific sampling methods;
2. The level of instrument intelligence includes real-time network communication interfaces RS-232 and RS-485, GPRS/CDMA, which receive information from measurement and control equipment, enabling remote sampling in all weather conditions, sudden sampling, and remote control sampling;
3. The system has multiple allocation methods and supports sampling methods such as' sample quantity/bottle ',' bottle quantity/sample ', and' allocation to all bottles'. These three sampling methods are flexible and can cover almost all methods;
4. The system can set the sample collection method (sampling volume, number of failed retries). And the ability to trigger abnormal sampling (with a set threshold), flexible multi condition triggering mechanism, and multiple triggering modes to meet customer needs;
5. The system can set the startup conditions of the program (time delay startup, quantity delay startup, status input delay startup) to fully meet the startup conditions of the customer's actual situation;
6. The sampler chamber has a large volume and is refrigerated to store the sampling liquid at all times. The sampling bottles (24) are arranged in a fan-shaped manner in a circular box, with a compact structure and a constant temperature of around 4 ℃ throughout the year to ensure that the water sample does not deteriorate;
7. 7. The 160 × 160 monochrome LCD screen displays Chinese characters and graphics, with LED backlight and menu operation, which is simple and convenient.
8. Equipped with on/off records to prevent unauthorized operation by unauthorized personnel;
9. Equipped with an inlet filter to prevent pipeline blockage;
10. Equipped with inlet flushing capability, it automatically flushes 1 to 3 times with the sampled water sample before each sampling to prevent cross contamination;
11. Capable of retaining standard samples;
