This probe accurately and easily measures a solution's conductivity or total ion concentration. The platinum-cell electrode increases accuracy by reducing polarization effects common in graphite conductivity probes. Measure conductivity in non-aqueous solutions, strong acids, and strong bases without damage to sensor body or sensing element. A built-in temperature sensor simultaneously reads temperature. Rechargeable battery offers long battery life. Includes micro USB cable.

Tariffs have driven up the cost of this item significantly. We apologize for the price increase. We are absorbing some of the impact to help teachers but are forced to pass most of it along.

Product Details
The Go Direct® Platinum-Cell Conductivity Probe has a range of 0 to 20,000 µS/cm, for optimal measuring precision in any given range. Its platinum-cell electrode provides increased accuracy by reducing polarization effects common in graphite conductivity probes. This sensing element, along with its epoxy body, also provide greater chemical compatibility during experiments, such as the base hydrolysis of ethyl acetate under various conditions. Conductivity measurements can be taken in non-aqueous solutions, strong acids, and strong bases without damage to the sensor body or the sensing element.

The probe's durability provides an opportunity for field investigations. Conductivity is one of the most common environmental tests of aquatic samples. This test quickly determines the total concentration of ions in a sample (but does not tell you the specific ions that are present).

Go Direct® Platinum-Cell Conductivity Probe also 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 to perform conductivity studies as a function of temperature.

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.
