PASPORT Temperature Sensor - PS-2125

Move to Wireless!

Recommended Alternative — The Wireless Temperature Sensor can perform most* of the functions of the PASPORT Temperature Sensor and long-term temperature data can be logged directly onto the sensor. Best of all, it connects directly** to your computers, tablets, smartphones and Chromebooks without the need for an interface and with no cables to get in the way.

* The Wireless Temperature Sensor has an attached stainless steel probe and cannot use other PASCO temperature probes.

**Devices without native Bluetooth® Smart connectivity will require a low cost USB adapter - see the product pages for details.



Our Temperature Sensor is reason enough to make the switch to probeware! Its stainless steel probe is more durable than a glass thermometer, allowing for years of student use. Its fast response rate means students spend more time analyzing data and less time waiting for results. The sensor's wide range (–35 °C to +135 °C ) covers the majority of temperature experiments in the student lab.

  • High resolution (0.0025 °C) allows students to investigate the small but significant temperature changes produced by chemical reactions, convection currents and skin temperatures at various points on the body.
  • Interchangeable probes – can be used with stainless steel, fast response or surface temperature probes. No recalibration required.
