{"product_id":"horiba-u-53-multiparameter-water-quality-meter","title":"Horiba U-53 Multiparameter Water Quality Meter","description":"\u003cp\u003eThe HORIBA U-53 is a field-portable multiparameter water quality meter built around a tungsten-lamp turbidity sensor, delivering ten simultaneous measurements from one submersible probe.\u003c\/p\u003e\n\n\u003cp\u003eThe difference between the U-53 and the U-52 is the turbidity light source. The U-53 uses a tungsten lamp rather than an LED — the configuration specified by turbidity methods that call for a white-light incandescent source. If your sampling program or discharge permit references tungsten-lamp turbidity, this is the model to specify. An automatic wiper keeps the optical window clean during extended deployments, and the integrated depth sensor records the exact depth of every reading for true water-column profiling.\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\u003cli\u003eTurbidity (tungsten lamp light source)\u003c\/li\u003e\n\u003cli\u003eWater depth\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. 3200164506) — surface water, flow cells, beaker readings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 m cable\u003c\/strong\u003e (part no. 3200164507) — typical shallow monitoring wells\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30 m cable\u003c\/strong\u003e (part no. 3200164508) — deep wells, reservoirs, full water-column profiling\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\u003eTurbidity compliance monitoring where a tungsten-lamp source is specified\u003c\/li\u003e\n\u003cli\u003eStormwater and construction site discharge monitoring\u003c\/li\u003e\n\u003cli\u003eLake, reservoir and estuary vertical profiling using the depth channel\u003c\/li\u003e\n\u003cli\u003eGroundwater monitoring well sampling and low-flow purge stabilization\u003c\/li\u003e\n\u003cli\u003eRiver, stream and watershed water quality surveys\u003c\/li\u003e\n\u003cli\u003eMunicipal and industrial wastewater and effluent characterization\u003c\/li\u003e\n\u003cli\u003eCoastal and brackish water monitoring using the seawater and salinity channels\u003c\/li\u003e\n\u003cli\u003eDredging and sediment plume monitoring\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, the #7801 U-53 turbidity cell, reference electrode tips, DO membrane caps, wiper rubbers, probe guards, O-ring sets, carrying cases, flow cells and calibration 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 Turb (Tungsten) Depth - 2 Meter Cable - 3200164506","offer_id":48226006728894,"sku":"3200164506","price":6380.0,"currency_code":"USD","in_stock":true},{"title":"pH ORP DO COND Salinity TDS Seawater Temp Turb (Tungsten) Depth - 10 Meter Cable - 3200164507","offer_id":48226006761662,"sku":"3200164507","price":6620.0,"currency_code":"USD","in_stock":true},{"title":"pH ORP DO COND Salinity TDS Seawater Temp Turb (Tungsten) Depth - 30 Meter Cable - 3200164508","offer_id":48226006794430,"sku":"3200164508","price":7320.0,"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-53-multiparameter-water-quality-meter","provider":"EnviroTech Services","version":"1.0","type":"link"}
