This versatile Thermo Scientific Orion VERSA STAR Benchtop meter kit comes with a pH/ISE/Temperature module. Kit includes the 8102BNUMD Orion ROSS Ultra pH Electrode, the 096019 automatic stirrer and paddle, and the 927007MD stainless steel ATC Probe (Mini-DIN connector; 1m cable). Kit also comes with the 810199 ROSS pH Buffer Kit which comes with one 1-pint (475mL) bottle each of pH 4.01 buffer (910104), pH 7.00 buffer (910107), pH 10.01 buffer (910110), 1 oz. (30mL) ROSS pH electrode storage solution (810001), one bottle of general pH electrode cleaning solution (900023), and one pH electrode storage bottle. The meter has a large, color graphic LCD display. The informative display shows readings, connections, time, date, sample ID, user ID and calibration information. The pH/ISE/Temperature module provides all the benefits of the pH module and is useful for fixing pH/ISE calibration errors without a complete recalibration with calibration editing. It has advanced ISE benefits such as auto-blank, timed end point, linear point-to-point, non-linear selectable auto-blank, low-concentration range stability, ISE ID and incremental techniques. Select from five modules to customize the four channels as you need it - it's versatile for you to configure how you need it for now or for later. Other available modules include Dissolved Oxygen/RDO/Temperature module, pH/Temperature module, Conductivity/Temperature module, and a module featuring LogR technology. No need to turn off your meter to switch modules –meter automatically recognizes module changes. 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 non-volatile memory holds up to 2000 data points with time and date stamp. Data transfer and updating meter software is easy with two USB and RS232 ports. Includes data analysis software for transferring stored results or displaying readings in real-time. Mix samples without a stir plate with direct control for two Orion Star stirrer probes (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.
