Use the Go Direct® Tris-compatible flat pH sensor to measure the pH of a solution or semisolid, such as food or soil.

Charge and store up to four Go Direct® Sensor Carts.

The Go Direct Chloride Ion-Selective Electrode (ISE) is used to measure the concentration of chloride (Cl^-) in aqueous samples.

Secure your Go Direct® sensors for field work.

Easily collect motion data without the need for additional interfaces.

The Go Direct Potassium Ion-Selective Electrode (ISE) can be used to measure the concentration of potassium (K⁺) ions in aqueous solutions.

The Go Direct Ammonium Ion-Selective Electrode (ISE) can be used to measure the concentration of ammonium (NH₄⁺) in aqueous samples.

The Go Direct Nitrate Ion-Selective Electrode (ISE) can be used to measure the concentration of nitrate (NO₃^-) in aqueous samples.

The Go Direct Sound sensor is used to easily capture and evaluate waveforms. It directly connects via Bluetooth® wireless technology or wired via USB.

Go Direct Photogate is a double-gate sensor that includes two photogates built into the arms of the sensor, which accurately measures velocity and acceleration.

The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit.
