SOIL EC SENSOR RY-C10

Ry-c10 av conductivity sensor yog ib tug sensor tsim los soj ntsuam thiab kawm av conductivity. Cov khoom tseem ceeb yog graphite electrode thiab kub compensated thermistor, nws yog cov qauv yooj yim, kev ua haujlwm ruaj khov thiab cov ntaub ntawv raug thiab lwm yam.Dua rau thaj chaw loj ntawm Tuam Tshoj, cov ntsev muaj pes tsawg leeg ntawm cov av tov nyob rau hauv txhua cheeb tsam yog txawv. Txhua lub sensor yuav tsum tau ntsuas hauv chav kuaj ua ntej tawm hauv lub hoobkas. Cov txheej txheem calibration yog ua nyob rau hauv KCl los yog NaCl tov. Raws li cov ntsev muaj pes tsawg leeg ntawm cov av hauv thaj chaw ua haujlwm, ib pawg KCl lossis NaCl kho cov kev daws teeb meem nrog ntau qhov sib txawv tau npaj, xws li 0.01, 0.{{ 10}}5, 0.1, 0.15, 0.2mol / l, Cov khoom siv hluav taws xob tsis tu ncua ntawm qhov ntsuas tau hloov kho ntawm 1, thiab qhov ntsuas kub tau qhib thaum ntsuas. Ib txheej ntawm conductivity qhov tseem ceeb ntawm 25 degree yog ntsuas los ntawm qhov tsis tshua muaj concentration mus rau qhov kev daws teeb meem siab concentration, feem. Piv nrog rau cov txheej txheem kho, ib daim duab yog tsim, thiab tom qab ntawd siv lub quadratic polynomial haum kom tau txais cov nqi ntsev nrog qhov tseeb. Cov neeg siv tuaj yeem koom tes nrog cov av noo noo sensor kom tiav txoj kev tshawb fawb dynamic ntawm av dej thiab ntsev hloov.
