I. Implementation Standards
HJ / T372-2007 "Technical requirements and detection methods for automatic water sampler"
2009 《水质样品的保存和管理技术》 HJ 493 － 2009 "Preservation and Management Technology of Water Quality Samples"
This meter is a new water quality automatic sampling equipment carefully designed and built by our company based on ten years of experience. It has a variety of sampling methods such as timing, time proportion, over-standard sample retention, synchronous sample retention and external control sampling. It is mainly used in river sections and drinking. Water quality automatic monitoring stations in water sources and other occasions.
The equipment can work in coordination with the on-site data acquisition instrument or industrial control computer to realize functions such as automatic sample retention, automatic bottle closure, and automatic addition of fixative (optional), which provide necessary support for the automatic water quality monitoring system.
Third, the main functional characteristics
设备采用压缩机制冷技术进行低温控制，常年恒温在 4 ± 2 ℃范围内； 1. Low-temperature refrigeration: The equipment uses compressor refrigeration technology for low-temperature control, and the constant temperature throughout the year is in the range of 4 ± 2 ℃;
区别于常规水质采样器，该设备具有留样瓶瓶盖自动封闭功能，从而减少水样交叉污染，同时延长样品保存时效； 2 , automatic sealing bottle mouth function: different from the conventional water quality sampler, this device has the function of automatically closing the sample bottle cap, thereby reducing cross-contamination of water samples and prolonging the storage time of samples;
留样后用户可自主选择现场或远程自动排样； 3 , automatic emptying function: after the sample is reserved, the user can choose on-site or remote automatic automatic sampling;
支持电子锁密码开锁，可自动记录并上传开样品箱信息； 4 , access control system: support electronic lock password unlock, can automatically record and upload information to open the sample box;
当采样仪采集不到水样时，或者采集量不够时，导致留样失败会报警并保存记录； 5. Sample retention failure alarm function: When the sampler cannot collect water samples, or when the collection volume is not enough, the sample retention failure will cause an alarm and save the record;
排样后，可自动对采样瓶进行清洗； 6. Automatic rinse function: After the sample is arranged, the sampling bottle can be cleaned automatically;
具有通过监进行远程状态查询、参数设置、记录上传、远程采样等功能，大大降低现场维护的工作量； 7. Remote control function: It has the functions of remote status inquiry, parameter setting, record uploading, remote sampling, etc. through monitoring, which greatly reduces the workload of field maintenance;
具有定量、定时定量、时间等比例、超标留样、同步留样及远程采样等功能，可满足不同的环境采样监管要求； 8 , a variety of sampling modes: with quantitative, timing quantitative, time and other proportions, sample retention beyond the standard, synchronous sample retention and remote sampling and other functions, can meet different environmental sampling supervision requirements;
具有与在线监测仪同步采样、留样功能； 9. Synchronous sample retention function: has the function of synchronous sampling and sample retention with the online monitor;
仪器具有双重留样功能（将同步采集的水样分装在两个不同的采样瓶中，其中一瓶添加固定剂，另一瓶不添加，从而满足多成分分析需求）； 10. Dual sample retention function (optional): The instrument has a dual sample retention function (water samples collected simultaneously are divided into two different sampling bottles, one of which is fixed and the other is not added, so as to meet Multi-component analysis requirements);
具有当收到水质监测数据异常信号时，采样仪会自动留样、自动添加固定剂、自动密封瓶口等功能； 11. Excessive sample retention function: When the water quality monitoring data abnormal signal is received, the sampler will automatically retain the sample, automatically add fixative, and automatically seal the bottle mouth;
具有根据现场工控机需求，自动添加相应固定剂功能，添加固定剂类型支持硫酸、硝酸、盐酸、 NaOH 等； 12. Water sample storage function (optional): It has the function of automatically adding the corresponding fixative according to the requirements of the industrial computer on site, and the type of fixative supports sulfuric acid, nitric acid, hydrochloric acid, NaOH, etc .;
该设备具有单瓶、双重等分瓶模式； 13. Bottle splitting mode: the equipment has single bottle, double split bottle mode ;
具有报警记录、采样记录、开关门记录、停电记录、采样瓶状态记录等； 14. Records: alarm records, sampling records, door opening and closing records, power failure records, sampling bottle status records, etc .;
设备具有断电自动保护功能，上电自动恢复工作，数据不丢失； 15. Power-off protection: The device has automatic power-off protection function and automatically resumes work after power-on without data loss;
设备具有将任一采样瓶自动移至正面，方便提取样品； 16. Convenient sampling design: the device has the ability to automatically move any sampling bottle to the front to facilitate sample extraction;
控制部分与机械取水部分完全分离，仪器安全性及稳定性更好。 17. Hydropower separation design: The control part is completely separated from the mechanical water taking part, and the safety and stability of the instrument are better.
