Orion Star A329 pH/ISE/Conductivity/Dissolved Oxygen Portable Multiparameter Meter Kit

Thermo Scientific Orion Star A329 pH/ISE/Conductivity/RDO/Dissolved Oxygen Portable Meter

The Thermo Scientific Orion Star A329 pH/ISE/Conductivity/RDO/Dissolved Oxygen Portable Meter 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.

Features and Benefits

• 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 USA/NIST 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 in conductivity readings, selectable reading reference temperatures of 5, 10, 15, 20 or 25 ºC 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
• Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing
• 3 year meter replacement warranty
