Instrumentation Amplifier

The Go Direct Electrode Amplifier offers an affordable way to expand your experiment options. Its BNC connector provides the flexibility to attach and remove a Vernier electrode, such as the pH Electrode, Flat pH Electrode, ORP Electrode, ISE electrode, or a third-party electrode. You can explore pH one day and potassium concentrations the next.   Because the Go Direct Electrode Amplifier is compatible with third-party electrodes, students learn consistent calibration and handling techniques on one amplifier using one software program. When electrodes expire or become damaged you need only replace the electrode—lowering your overall equipment costs.   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 Graphical Analysis™ 4 app or LabQuest 2 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. Specifications Units: pH or mV Input range (mV): ±1000 mV Input range (pH): 0 to 14 pH Accuracy with new electrode (mV): ±20 mV Accuracy with new electrode (pH): ±0.2 Connections: Wireless: Bluetooth Wired: USB

The Go Direct Voltage Probe combines a wide input voltage range and high precision, making it an excellent choice for lab investigations of both AC/DC circuits and electromagnetism. Use this differential probe to measure the voltage in simple circuits, to study basic principles of electrochemical cells, or to investigate the resistivity of different metals. With a range of ±15 V, this system is ideal for use in “battery and bulb” circuits. Go Direct Voltage is capable of kHz sampling and mV resolution, so you can also use it to capture more difficult electric potentials, such as the electromagnetic field induced in a coil by a moving magnet. This single sensor can take the place of several voltmeters in your classroom. The Go Direct Voltage Probe can be used in a variety of experiments: Measure potential difference at various places in series and parallel circuits. Investigate Ohm’s law in simple circuits. Measure the voltage across a capacitor in RC and RLC circuits. Explore Faraday’s law and induced EMFs in a coil of wire. Specification: Input voltage range: ±15.0 V Maximum voltage on any input: ±15 V Typical resolution: 0.5 mV Power: Internal rechargeable battery or USB connection Connections: Wireless: Bluetooth Wired: USB Included: Go Direct Voltage Probe Micro USB Cable
