Thaum twg DEJ DEJ SCECTING SCRORS xav tau calibration?

Los txiav txim siab seb cov dej online zoo saib xyuas cov sensor yuav tsum tau ntsuas, koj tuaj yeem ua nws los ntawm cov hauv qab no:

1. Khi mus saib lub voj voog calibration

- Xa mus rau lub sensor cov lus qhia lossis cov lus pom zoo txhawb kev soj ntsuam cov tshuaj hauv online yog qhov feem ntau pom zoo ua kom muaj qhov sib txawv ib zaug li ib zaug {{3} parts; Thaum yaj cov pa oxygen yuav yog ntsuas ib hlis ib zaug ib zaug mus txog, ntsuas hluav taws xob teev cia kom tau txiav txim siab .

2.}} Saib cov ntaub ntawv cov yam ntxwv

- Cov ntaub ntawv txawv txav hloov: yog tias cov ntaub ntawv ntsuas maj mam hloov pauv, thiab ntau dua li cov teeb meem sab nraud, nws yuav yog qhov teeb meem sab nraud

- Cov ntaub ntawv Drift: Lub ntsuas ntsuas ntsuas tus nqi txuas ntxiv rau ib qho kev coj ua tau zoo thiab tsis tau ua kom tiav, thaum lub sij hawm ntsuas qhov tseeb, thaum lub sij hawm tiag tiag dej ua kom nruj tsis tau hloov pauv {}}

3. sib piv nrog lwm cov ntaub ntawv tshuaj xyuas

- sib piv nrog lwm cov sensors: yog tias cov ntaub ntawv ntawm lub sensor tau sib txawv ntawm cov khoom siv hluav taws xob, yog tias cov ntaub ntawv kev xav tau zoo li qub, yog tias cov ntaub ntawv kev xav tau zoo tib yam, yog tias cov ntaub ntawv kev xav tau zoo ib txwm muaj, yog tias cov ntaub ntawv {sensor thiab tag nrho cov organic carbon (TC) sensor yog qhov txawv txav, thaum lub Cov ntaub ntawv Sensor yog ib txwm muaj, nws yog qhov tsim nyog los xav txog calibrating lub cod sensor {}}

- Kev sib piv nrog cov ntaub ntawv sim ua: Tsis txhob sib piv cov ntaub ntawv ntawm online ammonia nitrogen sensor yog qhov txawv ntawm chav kuaj spectrophotometric Tus nqi .

4.} Xyuas cov xwm txheej sensor

Cov tsos tshuaj xyuas: tshuaj xyuas seb puas muaj av, puas tsuaj, nws yuav cuam tshuam rau qhov chaw ntsuas hluav taws xob, nws yuav ua rau qhov ntsuas tsis raug, nws yuav ua rau qhov ntsuas tsis raug rau {}

- Kev Tshuaj Xyuas Kev Ua Tau Zoo: Tshawb xyuas cov ntsuas kev ua tau zoo xws li lub sijhawm teb chaws yog qhov ua tau ntev dua, tom qab kev ntsuas dej yog qhov ua tau ntev dua, tom qab kev ntsuas dej kom ncav tau ntev dua.

V .} Xav txog thaj chaw ib puag ncig

- Changes in environmental conditions: If the ambient temperature, humidity, pressure and other conditions of the water quality online monitoring sensor change significantly, beyond the applicable range of the sensor, it may affect its performance and require calibration. For example, in hot seasons, the measurement accuracy of some sensors may be affected.

- Kev tshuaj xyuas cov dej ua tau zoo: thaum cov tshuaj lom neeg ua haujlwm zoo, tshwj xeeb yog qhov ua kom pom tseeb, feem ntau hloov pauv tau, feem ntau hloov pauv ntawm cov khoom siv hluav taws xob hnyav
