Laboratory Benchtop ION/pH/ORP/Temp Meter

Suntex SP-2510 Laboratory Benchtop ION/pH/ORP/Temp Meter ingeniously designed to intuitively display the measurement status. SP-2510 features USB Type-C power supply and the capability to connect to a printer. Generous memory capacity accommodates an impressive 60,000 sets of measurement data. The intuitive and visual calibration graphics make it especially suitable for educational purposes, setting it apart not only with its calibration reminder function but also with its uniqueness. The screen offers diverse display modes catering to specific experimental data needs. Linear and segmented calibration modes allow for flexible selection of the most suitable calibration method. Encompassing various brands of standard solutions, this provides greater flexibility for your calibration needs. It can display a 3-minute trend graph, continuously tracking changes in sample values. Also, features ion selective method and direct reading of ppm unit.
