The CellaTemp® PA 29 is equipped with a special blocking filter and sensor. This means that the measurement is not influenced by daylight or laser radiation. The CellaTemp® PA 29 also reacts much less sensitively to reflective external radiation from hot objects in the environment than conventional pyrometers that measure short wavelengths. Due to the large measuring ranges and the many optical variations, the CellaTemp® PA 29 can be used for a wide variety of applications in the metalworking industry. In particular, it is used for temperature measurement of aluminium and bare metals at low temperatures.
