Manufactured by Trovan in Europe, AKC Reunite temperature sensing ISO Microchips +Temp are seamless, 100% bioglass encapsulated transponders with no plastic parts. This seamless design helps ensure the lifetime integrity of the microchip, and its parylene coating prevents migration. Our all-in-one syringe delivery device also features medical-grade needles that are arguably the sharpest in the industry. Temperature can be read when microchip is scanned by compatible temperature-reading-scanners, like the AKC Reunite ProScan +Temp or HomeAgain® Universal WorldScan Plus™ (please verify directly with manufacturer.) Temperature is directional and ideal for well-pet visits, but should not be used as a substitute for rectal temperature.
