Introduction: The sampler is mainly used in the automatic monitoring system of surface water quality of river sections and drinking water sources. It can accept on-site industrial computer control, integrate with various online monitors, and work in coordination. When there is abnormal detection or special sample retention requirements, it can realize automatic sample retention, automatic emptying of water samples, and automatic sealing of the bottle mouth. It is an essential part of the surface water quality automatic monitoring system. Features: 1. It has the function of refrigerating water samples, and the temperature is (4±2)℃; 2. It has the functions of saving sampling records, fault information and alarm information of sample storage temperature exceeding the standard; 3. The sample bottle is made of glass, with a capacity of ≥500mL; 4. The sample bottle has a sealing function; 5. It has the function of automatically emptying the sampling bottle after retaining the sample, and has the functions of emptying the pipeline and rinsing the pipeline; 6. With access control system, door opening and closing records; 7. With sample retention failure alarm function; 8. It has working modes such as timed sample retention, time-proportional sample retention, synchronous sample retention, external control sample retention, and over-standard retention sample, and has the function of immediate sample retention. It has the functions of flow proportional sample retention, liquid level equal proportional sample retention, remote control sample retention, remote start, and remote setting; 9. With automatic rinsing function of sample bottle; 10. With single sampling, mixed sampling function; Technical parameter: Sample bottle: 500mLX12 bottle Single retention sample volume: 10ml ~ 500ml can be set Time-proportional sample retention interval: 1min～9999min can be set Sampling error: ±7% Equal-proportional sampling error: ±8% Temperature control accuracy: 4±2℃ Horizontal sampling distance: ≥80 meters Sampling vertical height: ≥8 meters Empty residual volume of sample bottle: ≤2mL Air tightness of piping system: ≤-0.085MPa Average trouble-free continuous running time: ≥1440h/time Insulation resistance: >20MΩ Communication interface: RS-232 interface Analog interface: 4mA～20mA Digital input interface: switch Dimensions: 400mm×400mm×700mm (length×width×height) Average power: 75W Working power supply: AC220V±22V, 50Hz±0.5Hz Working environment temperature: 5℃～40℃ Working environment humidity: ≤85%RH System clock time control error: Δ1≤0.1% and Δ12≤30s Working voltage: AC220V±10%, 50Hz±1Hz
