The Thermo Scientific Orion Stara3295 pH/ISE/Conductivity/RDO/Dissolved Oxygen portable meter kit is the top choice for advanced multiparameter measurements on location. Get the information you need quickly and easily from the large, backlit graphic LCD display. Informative display can show each parameter with temperature individually or all three with temperature on one screen. Additional helpful icons include electrode status, time, date, sample ID, user ID and calibration points. Advanced features such as stability and averaging options provide additional options allowing for laboratory accuracy everywhere you need it.
 
Anyone can use this meter with its plain language screen prompts, soft keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese
Don't miss a reading - AUTO-READ™ locks in the stable reading on your screen, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals
Up to 5 point pH calibration with automatic recognition for USAIST and DIN buffers
Fix pH and ISE calibration errors without a complete recalibration with calibration editing
No need to worry about DO probe compatibility - the meter accepts and automatically recognizes Orion polarographic and RDO optical/luminescence-based probes
It's easy to get accurate DO results with automatic temperature, automatic/manual barometric pressure and automatic salinity compensation when used with simultaneously with conductivity
Calibrate for DO using water-saturated air, air-saturated water, a Winkler titration or zero point calibration
Selectable cell constant allows for use with 2- or 4-cell conductivity cells
For advanced accuracy, selectable reading reference temperatures of 5, 10, 15, 20 or 25 °C with linear, non-linear, nLFu or USP/EP curve options
Choice of practical salinity or natural sea water curves for salinity readings
Linear or ISO/EN 27888 curves for TDS
Whether you use ISE infrequently or have multiple samples every day - up to 5 point ISE calibration with advanced features such as timed end point, linear point-to-point, non-linear selectable auto-blank and low-concentration range stability
Non-volatile memory holds up to 5000 data points with time and date stamp
Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software
User and sample ID fields for additional data accuracy
Stores up to 10 methods allow for customized procedures to differentiate between tests and/or users
Four AA batteries (included) provide over 800 hours of operation or purchase the universal power adapter (sold separately) to use AC power
