MODEL: HX1000
Online chlorophyll a tester
Because of water eutrophication, the fast growth of algae material has become many lakes, reservoirs, river or sea serious environmental problems; Chlorophyll a concentration and algal density has a good correlation with fluorescence method can fast and reliable monitoring chlorophyll a. Water changes of water has sudden change of sexual characteristics, water quality change amplitude often beyond the waterworks can handle range, to the operation of the water and water supply have a direct impact on water quality; It is necessary to water source water quality monitoring early warning, through monitoring the change of water quality, water to provide timely information, timely adjustment of the plant operation process, ensuring the security of water supply water quality has great significance. As online testing instrument, should have high accuracy, good reproducibility, low operation cost and maintaining the characteristics of little or no maintenance. HX1000 type chlorophyll a monitor and the characteristics of above outside can also compatible PH, DO, turbidity, conductivity, the parameters such as temperature, Be a very ideal source water quality monitoring instruments. Test principle: when specific wavelength of light irradiation chlorophyll a and chlorophyll a stimulated will emit a wavelength longer fluorescence; Through the monitoring of fluorescence intensity of light can accurate determination of the content of chlorophyll a.
Main technical parameters:
1, range: 0-300 PPB; 2, accuracy: plus or minus 10%; 3, repeatability: + / - 0.5 PPB; 4, circulation type water sample survey: 0-5 l/min, the typical flow 0.5 l/min, No parasitic reflection of light, than open measuring instrument have higher sensitivity, 5, output signal: 4-20 ma isolation output, 4 road with dead zone and the time delay function of the relay output; Another optional RS232 and RS485 - MODBUS output, can external computer download historical data; 6, screen show: 240 * 128 pixels with backlit LCD display, can store a month of history curve, built-in Chinese operation menu, touch screen great convenience user operation management; 7, power: 220 vac, 50 hz, 8, shell: IP65, plating steel for indoor use; 9, size: 500 * 300 * 200 (high * width * thick);
