Go Direct® Platinum-Cell Conductivity Probe
Perfect for AP Chemistry and college general chemistry, Go Direct Platinum-Cell Conductivity provides an accurate and easy measurement of a solution’s conductivity or its total ion concentration. The platinum-cell sensing element provides high accuracy and chemical compatibility when measuring non-aqueous solutions, strong acids, and strong bases. This probe connects via Bluetooth® wireless technology or via USB to your device.
Go Direct Platinum-Cell Conductivity has a range of 0 to 20,000 μS/cm to provide optimal precision in any given range. The 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 sensing element.
The durability of this probe provides the 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. (Note: test does not tell you specific ions that are present)
This probe features a built-in temperature sensor to simultaneously read conductivity and temperature. Automatic temperature compensation allows students to calibrate the probe in the lab and 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.
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 our free Vernier Graphical Analysis™ app, as well as Vernier Graphical Analysis Pro and LabQuest® 3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting–no interruptions or inconvenience to you or your students.
Wireless or Wired—The Flexibility to Choose
Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our free Vernier Graphical Analysis™ app–no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the solution best for your classroom or laboratory.
