Go Direct® Chloride Ion-Selective Electrode

Go Direct® Chloride Ion-Selective Electrode product image

The Go Direct Chloride Ion-Selective Electrode (ISE) is used to measure the concentration of chloride (Cl-) in aqueous samples. It connects via Bluetooth® wireless technology or wired via USB to your device.

Description

The concentration of chloride gives a quick measurement of the salinity of water samples. Use the Go Direct Chloride Ion-Selective Electrode to wirelessly measure chloride levels in ocean saltwater or salt in food samples.

The versatile BNC connector allows students to easily replace the electrode when it expires or becomes damaged. You need only replace the electrode and not the entire sensor—lowering your overall equipment costs.

The Go Direct Chloride Ion-Selective Electrode has a combination-style, non-refillable, gel-filled electrode. Unlike other ISEs available from Vernier, the Go Direct Chloride Ion-Selective Electrode has a solid-state membrane that does not need to be replaced.

Rechargeable Battery—Ready When You Are

The Go Direct 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.

Important: Ion-Selective Electrodes require good chemical technique and careful calibration to obtain accurate results; they are not recommended for middle school or elementary students.
