This probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab, then make measurements outdoors without temperature changes affecting data (temperature compensation can be turned off if needed). Rechargeable battery offers long battery life. Includes micro USB cable.

Product Details
The Go Direct® Conductivity Probe determines the ionic content of an aqueous solution by measuring its electrical conductivity. It features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab, then make measurements outdoors without temperature changes affecting data. This temperature compensation can be turned off to perform conductivity studies as a function of temperature.

Use the Go Direct® Conductivity Probe in a variety of experiments:

• Demonstrate diffusion of ions through membranes
• Investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions
• Measure Total Dissolved Solids (TDS)

Product Features

• The probe has a range of 0 to 20,000 µS/cm to provide optimal precision in any given range.
• An alternating current at its electrodes prevents polarization and electrolysis, reducing contamination of solutions.
• Its ABS-body graphite electrode resists the corrosion typical in metal electrodes.

Rechargeable Battery—Ready When You Are
The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from the award-winning Vernier Graphical Analysis® Pro app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the included charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose
The Go Direct® sensor connects directly to your mobile device and Chromebook™ or other computer using the Vernier Graphical Analysis® Pro app—no additional equipment or software purchases are necessary. The sensor also can be used wired via USB or wirelessly via Bluetooth® technology, allowing you to choose the solution best for your classroom or laboratory.
