Every parameter appears on screen at once, logs to internal memory, and downloads to a PC using the U-50PC software. Control unit and probe are both built for wet, dirty work in monitoring wells, streams and treatment plants.\u003c\/p\u003e\n\n\u003ch3\u003eMeasured parameters\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003epH\u003c\/li\u003e\n\u003cli\u003eORP (redox potential)\u003c\/li\u003e\n\u003cli\u003eDissolved oxygen (DO)\u003c\/li\u003e\n\u003cli\u003eElectrical conductivity\u003c\/li\u003e\n\u003cli\u003eSalinity\u003c\/li\u003e\n\u003cli\u003eTotal dissolved solids (TDS)\u003c\/li\u003e\n\u003cli\u003eSeawater specific gravity\u003c\/li\u003e\n\u003cli\u003eTemperature\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCable lengths\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 m cable\u003c\/strong\u003e (part no. 3200164509) — surface water, flow cells, beaker and bucket readings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 m cable\u003c\/strong\u003e (part no. 3200164510) — typical shallow monitoring wells\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eChoose the length to match your deepest measuring point.\u003c\/p\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGroundwater monitoring well sampling and low-flow purge stabilization\u003c\/li\u003e\n\u003cli\u003eSurface water surveys of rivers, lakes, streams and reservoirs\u003c\/li\u003e\n\u003cli\u003eCoastal, estuarine and brackish water monitoring using the seawater and salinity channels\u003c\/li\u003e\n\u003cli\u003eMunicipal and industrial wastewater and effluent discharge checks\u003c\/li\u003e\n\u003cli\u003eDrinking water source and distribution spot checks\u003c\/li\u003e\n\u003cli\u003eAquaculture, irrigation and agricultural runoff monitoring\u003c\/li\u003e\n\u003cli\u003eEnvironmental compliance sampling and site characterization\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eDocumentation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/pdf\/water_quality\/horiba_u-50.pdf\"\u003eU-50 Series specifications (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/Manuals\/Horiba_Manuals\/U-50_Manual_revised_0409.pdf\"\u003eU-50 Series instruction manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/Manuals\/Horiba_Manuals\/U-50PC_Instruction_Manual.pdf\"\u003eU-50PC software instruction manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.geotechenv.com\/Manuals\/Horiba_Manuals\/U-50_Flow_Cell_Instruction_Manual.pdf\"\u003eU-50FC flow cell instruction manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eParts \u0026amp; accessories\u003c\/h3\u003e\n\u003cp\u003eReplacement pH, ORP and DO sensors, reference electrode tips, DO membrane caps, probe guards, O-ring sets, carrying cases, flow cells, calibration beakers and standard solutions are all stocked — see the \u003ca href=\"https:\/\/envirotechonline.com\/collections\/horiba-parts-accessories\"\u003eHoriba Parts \u0026amp; Accessories\u003c\/a\u003e collection.\u003c\/p\u003e\n\n\u003cp\u003eBrowse all \u003ca href=\"https:\/\/envirotechonline.com\/collections\/horiba\"\u003eHORIBA instruments\u003c\/a\u003e.\u003c\/p\u003e","brand":"Horiba","offers":[{"title":"pH ORP DO COND Salinity TDS Seawater Temp - 2 Meter Cable - 3200164509","offer_id":48226006466750,"sku":"3200164509","price":4060.0,"currency_code":"USD","in_stock":true},{"title":"pH ORP DO COND Salinity TDS Seawater Temp - 10 Meter Cable - 3200164510","offer_id":48226006499518,"sku":"3200164510","price":4390.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/9926\/6750\/products\/horiba-3200164501-multiparameter-meter-6-ft-2-m-cable-9960022.jpg?v=1659466720","url":"https:\/\/envirotechonline.com\/products\/horiba-u-51-multiparameter-water-quality-meter","provider":"EnviroTech Services","version":"1.0","type":"link"}
