DR-803M4 Water Quality Automatic Sampler Introduction: The water quality automatic sampler is suitable for the shore-type automatic water quality monitoring station. The sampler can be connected with the surface water quality automatic monitoring system to realize the functions of timed sampling, time proportional sampling, synchronous sampling, externally controlled sampling, over-standard sampling, and immediate sampling. . The sampling bottle has a sealing function, automatic emptying function and automatic rinsing function, and the sampling bottle can be recycled. The water quality automatic sampler also has protection functions such as password protection and power-off protection, and has the characteristics of small size, automatic refrigeration, and convenient installation. It is an important part of the shore-type water quality automatic monitoring station. Features: 1. Various sampling methods: timing sampling, time proportional sampling, synchronous sampling, external control sampling, over-standard sampling, immediate sampling and other functions; 2. Bottle splitting method: apheresis; 3. Automatic rinse: automatically rinse the pipeline and sampling bottle with the original water sample before sampling; 4. Automatic emptying: automatic emptying of sampling bottles and pipelines; 5. Low temperature refrigeration: electronic temperature control, water sample storage temperature is 4℃±2℃; 6. Electronic access control: open the electronic control lock after the password verification is passed; 7. Communication: can remotely read and set working parameters through the serial port; 8. Power-off protection function: After the instrument is powered off and re-energized in the running state, the instrument can automatically return to the operating state before the power-off, and the parameters of the instrument will not be lost after the power-off; 9. Sampling record function: It can record information such as time, sampling amount, sampling mode, etc. of each sampling, and can store 1000 sampling records; 10. Power failure record: It can record the time of each power failure and power-on of the sampler, and can store 1000 power failure records; 11. Alarm record: When sampling fails, alarm information can be generated, and 1000 alarm records can be stored. Technical parameter: Number of sampling bottles: 6 bottles Maximum capacity of a single bottle: 500ml (can be customized) Single sampling volume: 10ml～500ml Sampling interval: 1min～9999min Sampling error: ±7% Equal-proportional sampling error: ±8% Horizontal sampling distance: ≥65 meters Sampling vertical height: ≥6.5 meters 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: 380mm×380mm×590mm (length×width×height) Average power: 75W Working power supply: AC220V±22V, 50Hz±0.5Hz Working environment temperature: 4℃～50℃ Working environment humidity: ≤85%RH System clock time control error: Δ1≤0.1% and Δ12≤30s Temperature control error: ±2℃
