Triple Sensor, Ver. 3
Three miniature sensors for measuring directions, barometric pressure / altitude, and temperature: These comprise PRO TREK’s core technologies for high-precision detection of sudden changes in natural phenomena. In 2013, CASIO has developed a dramatic upgrading of Triple Sensor’s with its advance to a 3rd generation.
Triple Sensor’s History of Evolution
Triple Sensor, Ver. 1 (1994-2001)
Triple Sensor debuted in 1994. Operating on battery power, it revolutionized the wristwatch with its ability to measure directions, barometric pressure / altitude and temperatures.
Triple Sensor, Ver. 2 (2002-2012)
A Triple Sensor with CASIO’s original Tough Solar rechargeable solar battery system providing the power required to conduct sensor measurements.
Next-generation Triple Sensor realised through advanced sensor technologies
