Our 5th generation benchtop series consists of single and multi-parameter models, with or without Bluetooth connectivity. The 6377MB / 6377BEU is a multi-parameter pH / ORP / Conductivity / Salinity / TDS / Temperature Bluetooth benchtop meter that pairs with iOS tablet to enable the same user experience as users favorite apps while providing graphing, guided calibration procedures, GLP-compliant data storage, data sharing, cloud data storage and user-defined compliance policies. Renowned Accuracy and Repeatability Repeatable, accurate results achieved with up to 5 points NIST or US buffer calibration for pH, 1 point ORP offset calibration and conductivity calibrations in multiple ranges. Great User Experience Streamlined and modern design is paired with a large, high contrast backlit LCD, buttons with tactile and audio feedback, and a detached electrode holder arm. Improved Electrode Serviceability and Low Cost of Ownership Standard BNC connector for pH or ORP electrodes, 8-pin DIN for conductivity and temperature electrodes. App-Enhanced Productivity Free iOS app is as easy and convenient to use as users favorite app, and allow complete control of all on-meter functionality plus guided calibration procedures and much more. Easily Share Data Locally or to the Cloud Share stored data to other apps such as Notes and Evernote or to cloud services such as Google Docs. High Information Availability Display pH, conductivity, salinity or TDS with temperature readings simultaneously with electrode efficiency, last calibration date and real-time graphing. GLP-Compliant Data Storage Greater than10k Sets of pH or conductivity and temperature data plus calibration data such as calibration date, buffers used, calibration slopes and calibration offsets. Transfer 750 saved measurement data from meter to app for sharing and further analysis. Measurement data includes pH, ORP or EC and temperature values and calibration information.
