Wireless Temperature Sensor (Local Stock)

Product Code: PS-3201-LS


Welcome to the modern thermometer. The Wireless Temperature Sensor transmits live data and allows students to continuously monitor, log, and plot temperature measurements on nearly any device. When lab-time ends but the experiment continues, students can set the sensor to log data autonomously for days, weeks, or months, then download it for analysis later. This durable, wireless sensor features a stainless steel probe for the most demanding of applications, as well as a battery that lasts over a year*. It can be used in a wide array of experiments and activities because it measures small, but significant temperature changes produced by chemical reactions, convection currents, and even skin temperatures.

Note:  The rugged sensor housing/handle is rated for temperatures of -10 ºC to 40 ºC. This means it cannot be subjected to the same extremes as the stainless steel probe. For extremely low or high-temperature applications we recommend the Electrode Support to keep the sensor in the proper position during experiments.

*Battery life is based on typical usage in a secondary or college lab.
