Collecting multi-parameter data in the field is a breeze with Eutech’s CyberScan 650 multi-parameter series. The CyberScan PD650 delivers quick, lab-accurate measurements of pH and dissolved oxygen simultaneously. Auto-logging function records up to 500 data sets with date and time in GLP-compliant format. Plus, a comprehensive screen displays pH, dissolved oxygen and temperature readings simultaneously in addition to electrode status reports and calibration information. :: Simultaneously measures and displays three parameters :: ±1% full scale accuracy at 3-decimal resolution across a wide measurement range :: Ion-measurement capabilities with 3-digit resolution :: Selectable multi-point calibration for more accurate conductivity measurements or single-point calibration for quick, convenient calibration with no mistakes :: Measures 90.00mg/L in DO concentration and 600% in DO saturation—one of the widest dissolved oxygen measurement ranges offered in the handheld market today :: Fast and easy DO calibration with 100% calibration option against atmospheric air or 0% calibration against a zero solution :: Salinity, Temperature and Pressure Compensation—accurate readings under varying conditions :: No warm up time required with galvanic system of measurement :: One-Glance-Tells-All Screen Display with Backlight Electrode status report, calibration data and simultaneous display of up to 4 parameters :: Rugged and IP67-rated waterproof for applications in harsh environments. Meter floats on water! :: Easy-to-understand prompt messages for easy set-up, calibration and trouble-shooting :: Recorded readings individually stamped with time and date in GLP compliant format :: Auto-logging meter saves readings automatically within seconds to prevent data loss :: HI-LO limit alarm for easy quality control – Meter alerts when readings fall outside selected ranges :: Wireless Information Technology: No wires, no cables—Transfer data from meter to computer with the press of a button :: Non-Volatile Memory protects information and meter settings, even when batteries run out :: Four Levels of Password Protection prevents tampering or accidental data deletion :: Calibration Alarm: No more out-dated calibration settings CyberScan Carrying Kit Waterproof Electrodes RS232 Printer Adapters Applications Environmental: Test water quality, monitor health of aquatic ecosystems, survey surface and ground water drinking supplies, and meet EPA regulations. Water Quality Testing: For analyzing water hard water, untreated water, drinking water, effluent water, pool water and incoming process water. Ideal for all types of quality assurance and water quality testing. Industrial: For checking metal finishing, cooling tower water, printing fountain solutions, boiler water, brines, rinse tanks, ponds, pollution control, recirculating systems, waste water and industrial process systems. Useful for food analysis and quality assurance testing. Aquaculture: Use to monitor oxygen levels in catfish and shrimp farming; game stocking ponds; ornamental fish tanks and ponds; and other fish farming applications.
