Vernier Software & Technology Launches New Wireless Probe for AP & College-Level Chemistry

Vernier Graphical Analysis™ Pro

Ideal for Advanced Placement® (AP) Chemistry and college-level general chemistry, the affordable and durable Go Direct Platinum-Cell Conductivity Probe from Vernier Software & Technology helps students determine a solution’s conductivity or the total ion concentration with high accuracy and chemical compatibility.

“Our new probe has an epoxy body and platinum-cell sensing element that notably provides greater chemical compatibility. This probe enables students to measure the conductivity of strong acids, strong bases, and non-aqueous solutions during experiments without any risk of damaging the sensor,” said John Wheeler, CEO of Vernier Software & Technology. “The durable Go Direct Platinum-Cell Conductivity Probe automatically adjusts its conductivity range in response to the concentration of the given solution to provide students with the most accurate readings possible.”

Go Direct Platinum-Cell Conductivity features a wide 0 to 20,000 μS/cm range that ensures optimal precision during various experiments, such as exploring the base hydrolysis of ethyl acetate under various conditions and other common environmental tests of aquatic samples.

Go Direct Platinum-Cell Conductivity features a long-lasting, rechargeable battery, as well as a built-in temperature sensor to simultaneously read conductivity and temperature. The sensor’s automatic temperature compensation, which can be turned off to perform conductivity studies, allows students to calibrate the sensor in the lab and then make measurements outdoors without temperature changes affecting data.

Like all Go Direct sensors, Go Direct Platinum-Cell Conductivity connects via Bluetooth® wireless technology to any Chromebook™, computer, or compatible mobile device with either the Vernier Graphical Analysis™ or the Vernier Graphical Analysis™ Pro app. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing educators to choose the solution best for their classroom, lab, or other learning environment.
