Vernier's water resistant Go Direct Temperature Probe is a rugged, general purpose temperature sensor that students can use to monitor temperature. It connects wirelessly via Bluetooth® or it can be wired via USB to your device.

The Vernier Go Direct Temperature Probe gives students the advantage of go-anywhere, work-anywhere connectivity, its water resistance makes it the most durable Vernier temperature ever released.

Unlike a traditional thermometer, Go Direct Temperature allows students to collect real time temperature measurements of a single instance or over a period of time. Its temperature range and wireless capability make Go Direct Temperature the go-to sensor for real world applications.

The Go Direct Temperature Probe can be used in a variety of experiments:
• Conduct endothermic and exothermic reactions
• Investigate the freezing and melting of water
• Measure the energy content of foods
• Examine the absorption of radiant energy
• Monitor environmental conditions

Water Resistance:
The Go Direct Temperature Probe can be submerged in water for limited periods of time. It has been tested to a depth of one metre for up to 30 minutes. However, submerging the sensor impacts the radio operation by absorbing much of the energy. This may make it difficult or impossible to connect to the sensor while submerged, particularly if there are electrically noisy signals nearby, such as pumps or motors.

Rechargeable Battery — Ready When You Are
The Vernier Go Direct™ robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from Vernier's free Graphical Analysis™ 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
Vernier's Go Direct™ sensors connect directly to your mobile device, Chromebook or computer using Vernier's free Graphical Analysis™ app. No additional equipment or software purchases are necessary. Vernier Go Direct sensors can be used wired via USB or wirelessly via Bluetooth allowing you to choose the solution best for your classroom or laboratory.
