High-accuracy DEK multi-parameter water quality analyzer

Abstract

The invention discloses a high-accuracy DEK multi-parameter water quality analyzer, which comprises a power pump and a measuring cell. A metering device is arranged under the power pump; a metering sensor is arranged on one side of the metering device; a flow divider valve island is arranged under the metering device; a drain valve is arranged under the flow divider valve island; a reference receiving lamp is arranged on one side of the measuring cell; a projection lamp is arranged on one side of the reference receiving lamp; a pellicle mirror is arranged at a position, under the reference receiving lamp, on one side of the measuring cell; an upper high-pressure valve is arranged above the measuring cell; the measuring cell is arranged on the other side of the metering device; a measuringreceiving lamp is arranged on the other side of the measuring cell; a light path integration ring is arranged in the measuring cell; a lower high-pressure valve is arranged under the measuring cell. The high-accuracy DEK multi-parameter water quality analyzer provided by the invention has the advantages of low cost, high stability and high resolution ratio.

Description

technical field [0001] The invention relates to an analyzer, in particular to a high-precision DEK multi-parameter water quality analyzer. Background technique [0002] The multi-parameter water quality analyzer is an online analysis instrument and laboratory research needs as the service goal, with the provision of representative, timely and reliable sample information as the core task, using automatic control technology, computer technology and professional software , forming a complete system from sampling, preprocessing, analysis to data processing and storage, so as to realize online automatic monitoring of samples. The automatic monitoring system generally includes a power device, a metering device, and an analysis and measurement device. Certain disadvantages. At present, most of the emitting lights used by various instrument manufacturers are LED light sources.

Problems solved by technology

The automatic monitoring system generally includes a power device, a metering device, and an analysis and measurement device. Certain disadvantages. At present, most of the emitting lights used by various instrument manufacturers are LED light sources. Due to the characteristics of the product itself, the energy of the light source will gradually decrease with the passage of working time, resulting in the drift of the measurement data. It requires frequent calibration by personnel and wastes reagents. , which also increases labor costs, and the measurement accuracy of various instrument manufacturers is mostly around ±10%.

In some provinces and cities that implement dynamic control, enterprises will close their sewage valves when the emission concentration exceeds 5% of the limit value. At this time, the error range of ±10% is difficult to meet the requirements of the control system, which brings certain problems to people's use process. impact, for this reason, we propose a high-precision DEK multi-parameter water quality analyzer
