Abstract
The utility model discloses a multi-parameter online water quality analyzer, which comprises a microprocessor and a liquid crystal display (LCD), wherein the microprocessor is connected with the LCD, more than two alternating current (AD) sampling modules and a photoelectric isolation module with more than two channels are connected with the microprocessor, the alternating current sampling modules are used for acquiring data and is connected with a signal processing module, the photoelectric isolation module is used for outputting and is connected with a digital-to-analogue conversion (DAC) output module, and the DAC output module is connected with a voltage converting current module. According to the multi-parameter online water quality analyzer, a surface mount technology is adopted to greatly increase the integration degree; and parameters to be measured can be chosen as required, all channels are mutually independent and do not interfere with one another, and complex function switches and adjusting knobs are omitted, so that the whole device is small in volume and convenient to install and use. All parameters are set independently, and the LCD displays in Chinese and is clear to operate.
Description
Technical field
The utility model relates to the online Water Test Kits of a kind of multiparameter, belongs to the technical field of online analytical instrument of water quality.
Background technology
Present online Water Test Kits on the market only has single parameter, and the detection of accomplishing multiparameter like need just needs many analytical instrument co-operation; So just cause water quality detection very loaded down with trivial details.Existing water quality testing meter also exists intelligent degree not high simultaneously, and digital display interface is dull, the problem that volume ratio is bigger; It adopts many board members such as display board, mainboard, power panel, signal plate; Integrated degree is low, and result of use is not ideal enough, and cost is higher.
