Use Go Direct Gas Pressure Sensor to monitor gas pressure in a variety of experiments. It records accurate absolute pressure readings relative to the perfect vacuum reference point inside the sensor, allowing you to go below atmospheric pressure or up to 400 kPa. Easily change the displayed units to any one of seven options (kPa, mmHg, inHg, mbar, psi, atm, torr).

Vernier Go Direct Gas Pressure Sensor, tapered valve connectors (2) inserted into a No. 5 stopper, tapered valve connector (1) inserted into a No. 1 stopper, two-way valve, 18 inch Tygon tubing with Luer Lock connectors, 20 mL syringe, and white transpiration tubing clamps (2) to ease setup for experiments such as Boyle’s law.

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.

The Go Direct Gas Pressure Sensor can be used in a variety of experiments:

• Investigate Boyle’s law and Charles’ law
• Measure the production of oxygen gas produced when hydrogen peroxide is destroyed by the enzyme catalase
• Monitor plant transpiration
