SevenMulti meters provide the flexibility and convenience of measuring pH and ion concentration with durable plug-in measurement modules. Meters automatically recognize the specific expansion unit for quick and easy parameter changes and can also measure mV and temperature. Meters feature a maximum of nine calibration points with selectable linear or segmented algorithms as well as user-defined buffers; GLP-compliant measuring points; backlit display and easy-to-use text menus; and secure data management transfer software that allows saving, capturing, and recalling of results as well as calibration and display of graphs. Meters are also available with InLab 413 pH, InLab 410 pH, or InLab 730 conductivity electrodes. The LabX direct pH software allows data import into a customizable Windows Excel spreadsheet template. Measurement results are visualized as an online measurement curve. The Equipment Qualification (EQ) service for the SevenMulti meters consists of Design Qualification (DQ), Installation Qualification (IQ), and Operational Qualification (OQ) performed and documented by a certified and authorized field service technician. Service includes certification of instrument measuring amplifier voltage and pH reading. Also includes buffers for performance of general System Suitability Test (SST), meter logbook for complete documentation of EQ process, and ongoing instrument maintenance and disposition. Annual maintenance and re-qualification service is also available. Note: Service for sample changers, balances, and software is not included but is available separately; contact your eGM sales representative. pH Mode, Range: -2.000 to 19.999 Range (ISFET): 0.00 to 14.00 Resolution: 0.001/0.01/0.1 Resolution (ISFET): 0.01 Accuracy: +-0.002 Accuracy (ISFET): +-0.01 mV Mode, Range: -1999.9 to 1999.9 Relative Accuracy: +-0.1 Conductivity Mode, Range: 0.01 uS/cm to 1000 mS/cm, autos
