This Thermo Scientific Orion Star A214 pH/ISE/mV/Temperature Benchtop meter and Sodium ISE kit is the ideal choice for any lab. The kit includes the 8102BNUWP ROSS Ultra Glass Refillable pH Electrode, a general purpose, top performance glass body combination electrode with waterproof BNC connector for precise pH determinations. The pH response is independent of temperature changes and can be used on any pH meter with a BNC connection. The kit also comes with the 927007MD stainless steel ATC probe (Mini-DIN connector; 1m cable) which automatically corrects pH measurements for variation in electrode slope due to temperature change, and the 096019 automatic stirrer and paddle for use with Orion Star Meters and Orion 960 Titrator PLUS System which stirs samples for better accuracy and without having to deal with a separate stir plate and stir bar (fits Swing Arm Electrode Holder 96019). The included 8611BNWP ROSS Sodium combination electrode(Sure-Flow junction and waterproof BNC connector) allows quick, accurate and economical measurement of sodium in aqueous solutions and comes with Sodium BNC electrodes 1m cables, 50mL ROSS sodium electrode filling solution, 475mL sodium ionic strength adjustor (ISA), 475mL sodium known addition standard, 475mL 1000ppm sodium standard with ISA, 475mL 1000ppm sodium standard, 475mL sodium reconditioning solution, and 475mL sodium electrode storage solution. The BNWP connector is compatible with any standard BNC connector both on Orion meters and competitive meter models. The meter’s large, backlit graphic LCD display shows pH/mV/RmV/ISE results and temperature along with electrode status, time, date, sample ID, user ID and calibration points. For advanced users, features such as stability and averaging choices provide additional options. 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. The 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 five point pH calibration with automatic recognition for USA/NIST and DIN buffers. Whether you use ISE infrequently or have multiple samples every day – up to five 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. Fix errors without a complete recalibration with the calibration editing function. The non-volatile memory holds up to 2000 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. Mix samples without a stir plate with direct control of the Orion Star stirrer probe (096019, sold separately). Included electrode arm and newly-designed probe holder make it easier to maintain and place probes into samples. Works with almost every AC power source with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power. IP54-rated housing handles splashes and is wall-mountable if table space is a problem. Three year meter replacement warranty.
