The Go Direct Drop Counter precisely records the number of drops of titrant added during a titration and then automatically converts it to volume. It directly connects wirelessly via Bluetooth® or wired via USB to your platform.

Description

Conducting a titration has never been easier. Use Go Direct Drop Counter in conjunction with our other Go Direct sensors, such as Go Direct pH, Go Direct Conductivity, or Go Direct ORP, to perform acid-base, conductometric, or potentiometric titrations.

Designed with a wide drop-detecting area, Go Direct Drop Counter removes the need for precise burette alignment. We’ve also included a large sensor slot for conventional stick-style sensors and a smaller, adjustable slot for temperature probes. The adjustable clamp easily fits our Stir Station and most laboratory ring stands and lattices.

Rechargeable Battery—Ready When You Are

The robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis 4 app. 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.

Wired or Wireless—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our free Graphical Analysis 4 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.
