This design configuration allows the user to accurately monitor ORP without having to add any additional circuitry or components to your design. Communication with the Analog ORP Meter is done using only simple wiring and programming.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eORP (Oxidation-Reduction Potential) is a measure of the ability of oxidation and reduction of the aqueous solution, characterization of oxidizing or reducing the relative degree. Unlike a pH measurement that follows a logarithmic curve and therefore requires more calibration adjustments, ORP follows a linear relationship and does not need instrument adjustment as much as it needs electrode maintenance. ORP has proven to be a reliable method of measuring water quality and provides the operator with a single value of measurement regardless of which product, commodity, operation, treatment, or sanitizer is used, and regardless of varying field conditions or methods by which chemical is applied.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cspan style=\"color: #ff0000;\"\u003eAttention：\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe bottle cap of the probe contains protective liquid (3.3mol\/L KCL). Even if the bottle cap is screwed tightly, some protective liquid may still leak around the bottle cap, forming white crystals. But as long as there is still protective liquid in the bottle cap, it will not affect the life and accuracy of the probe. So please use it with confidence. It is recommended that the white crystals be poured back into the protective liquid in the bottle cap.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eWater Quality Testing\u003c\/li\u003e\n\u003cli\u003eAquaculture\u003c\/li\u003e\n\u003cli\u003eMarine Science\u003c\/li\u003e\n\u003cli\u003eHydroponic Gardening\u003c\/li\u003e\n\u003cli\u003eGeneral Chemistry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eModule Power:+5.00V\u003c\/li\u003e\n\u003cli\u003eModule Size: 40mmX27mm(1.57\"x1.06\")\u003c\/li\u003e\n\u003cli\u003eMeasuring Range:-2000mV—2000mV\u003c\/li\u003e\n\u003cli\u003eSuitable Temperature:5-70℃\u003c\/li\u003e\n\u003cli\u003eAccuracy:±10mv (25 ℃)\u003c\/li\u003e\n\u003cli\u003eResponse Time:≤20sec\u003c\/li\u003e\n\u003cli\u003eORP Probe with BNC Connector\u003c\/li\u003e\n\u003cli\u003ePH2.0 Interface(3 foot patch)\u003c\/li\u003e\n\u003cli\u003eZero calibration button\u003c\/li\u003e\n\u003cli\u003ePower Indicator LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.dfrobot.com\/wiki\/index.php\/Analog_ORP_Meter(SKU:SEN0165)\"\u003eProduct WiKi\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0165\/OPR%20meter%20V1.0%20Schematic.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0165\/OPR%20meter%20V1.0%20layout.pdf\"\u003eORP Meter PCB Layout\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0165\/ORPSensorSample.zip\"\u003eArduino sample code\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0165\/ORP%20Composite%20Electrode%20Manual.pdf\"\u003eORP Composite Electrode Manual\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003ePart List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eORP probe (BNC connector) x1\u003c\/li\u003e\n\u003cli\u003eORP probe circuit board x1\u003c\/li\u003e\n\u003cli\u003eAnalog cable x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Makerlab Electronics","offers":[{"title":"Default Title","offer_id":44220050768063,"sku":"MLE07023","price":6990.0,"currency_code":"PHP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/MLE07023.jpg?v=1748672070","url":"https:\/\/makerlab.ph\/products\/gravity-analog-orp-sensor-meter-for-arduino-sen0165","provider":"Makerlab PH","version":"1.0","type":"link"}
