Wireless Temperature Sensor

The Wireless Temperature Sensor is a general-purpose sensor found in many science labs. With a rugged, waterproof design and a long-lasting battery, students can spend more time collecting data and less time dealing with equipment.

Support

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
