Vernier GDX-ST Go Direct Surface Temperature

Designed for use in situations in which low thermal mass or flexibility is required. The Go Direct Surface Temperature Sensor connects via Bluetooth® wireless technology or via USB to your device.

This sensor has an exposed thermistor that results in an extremely rapid response time, making it perfect for use in air and water.

Use this sensor in a variety of experiments:
•Investigate the effect of temperature on solar panel output.
•Explore passive solar heating or solar collectors.
•Examine the warming function of nasal passageways.
•Discover the effect of vascularity on skin temperature recovery.

**Important: For use in air and water only. For temperature measurements in harsher environments that require a more durable probe, we recommend the Go Direct® Temperature Probe.**

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 award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3. 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.

Wireless or Wired—The Flexibility to Choose
Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our Vernier Graphical Analysis® 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 best solution for your classroom or laboratory.
