PMA8000 Outdoor Small Automatic Water Quality Monitoring System
PMA8000 outdoor small water quality automatic monitoring system consists of water collection unit, pretreatment and distribution unit, control unit, analysis unit, data acquisition and transmission unit, auxiliary unit, etc.
Compared with the traditional automatic water quality monitoring system, the new monitoring system has obvious advantages. It adopts customized movable monitoring cabinets, which have the advantages of beautiful appearance, convenient relocation, low construction cost, high equipment integration, perfect functions, and reliable operation. The micro station has functions such as rain protection, lightning protection, dust prevention, theft prevention, low temperature resistance, high temperature resistance, remote automatic data transmission, wireless communication, etc. It occupies a small area, does not require land acquisition, has a short construction period, and has little investment, making it suitable for wide distribution.
- Covers an area of less than 1㎡, no land acquisition, flexible installation;
- Integrated cabinet, highly integrated, compact size, outdoor rain and lightning protection, protection level IP55;
- Touch screen IPC, highly integrated with all control and display functions;
- Support arbitrary combination of conventional water quality parameter monitoring factors;
- Scientific pretreatment system can meet the monitoring requirements of different water bodies;
- Adopt the design concept of modular, intelligent and highly integrated, and realize the same functional configuration as the traditional station building water station at low cost;
- It supports wired and wireless transmission, which can adapt to the needs of multiple scenarios of outdoor sites;
- The construction period is short, the on-site project is simple, convenient to move, and the reconstruction in different places is fast;
- Have three-level management authority;
- Optional UPS uninterruptible power supply provides stable power to all instruments in the event of a power failure.
- The instrument adopts a ten-way valve with a sapphire valve core, with high wear coefficient, strong acid and alkali resistance, organic solvent resistance, strong service life, and high stability;
- The special design of the reference method does not affect the measured value of the light displacement of the digestion tank and the light pollution of the digestion cell;
- The instrument has the function of separating waste liquid, which realizes the separate storage of high-concentration reaction waste liquid and low-concentration cleaning waste liquid;
- The instrument has a dynamic dilution function, which can automatically adjust the dilution factor according to the range set on site;
- The instrument comes with a quality control function, which can automatically realize a variety of quality control functions such as blank test, standard sample verification, zero point verification, span verification, 24-hour zero point drift, 24-hour span drift, spike recovery, parallel sample test, etc.
- Online water quality monitoring of urban inland rivers, surface water assessment sections, drinking water sources, and river outlets;
- Rural sewage monitoring.
