How do I replace the battery of those PASCO Wireless Sensors that use coin cell batteries, such as Wireless Temperature (PS-3201) and Wireless pH (PS-3204)?
CR2032 batteries are available at many retail stores, online, or directly from PASCO in packs of 10: pasco.com/go?PS-3504.
Note that other PASCO Wireless Sensors with USB ports have built in rechargeable batteries that do not need replacement.
