Get high accuracy, premium performance and ultimate flexibility with the Thermo Scientific Orion Versa Star Pro Benchtop Meter with pH and Conductivity Modules. Meet your most challenging applications for pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity and temperature. Easily view measurements on the stunning color display and customize the four meter channels with interchangeable modules. View pH and conductivity simultaneously or view each channel separately. Log up to 2000 data point sets with time / date stamp and easily transfer logs to a printer or computer. Features: Onscreen measurement stability indicator lets you know exactly when your measurements are readySelectable read modes include Auto-Read to hold a stable readingContinuous to show changing readingsTimed to log data at specific intervals and Single-Shot to hold a reading after a specific wait time is reachedAudible alarms automatically notify you when a set offset value, high/low limit value, and calibration time interval are reachedEasily access, update and switch your preferred measurement settings, using ten password-protected methods per channelUniformly mix solutions using up to two meter-controlled stirrer probes that are easy to position and can be quickly rinsed between samplesData log collects and date/time stamps up to 2000 measurement sets with optional electrode ID, sample ID and account IDCalibration log stores 30 most recent calibrations per parameter with viewable graph for multipoint pH and ISE calibrationsEnsure measurement integrity by viewing the active calibration log while taking readingsNon-volatile meter memory preserves data and settings, even in the event of power lossMeter facilitates data transfers to a computer via USB or RS232 connectionsIP54-rated housing resists dust and splashes and can be wall-mounted if table space is limitedMeters include CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty Includes Orion Versa Star pH Measurement Module: Measure pH, mV, relative mV or ORP with temperaturePerform up to a six point pH calibration using automatic buffer recognition of NIST, DIN or user-defined buffer groups with choice to manually enter custom buffer valuesCalibration editing option allows individual points to be fixed without a full recalibration Includes Orion Versa Star Conductivity Measurement Module: Measure conductivity, TDS, salinity or resistivity with temperaturePerform up to a six point conductivity calibration with calibration editing option that allows individual points to be fixed without a full recalibrationAuto-ranging conductivity values offer consistent readings across entire measurement range without need to recalibrateUse linear, non-linear, EP (USP) or off conductivity temperature compensation with 5, 10, 15, 20 or 25C reference temperatures Includes: Versa Star Pro meter with pH module and conductivity module8157BNUMD ROSS Ultra Triode epoxy-body pH/ATC electrode013005MD Orion 4-cell (K=0.475) conductivity probe810199 ROSS pH buffer and storage solution kit011007 Orion 1413 S conductivity standardElectrode stand, universal power adapter, USB cable and literature Note: WILL NOT SHIP TO RESIDENTIAL ADDRESSES.
