*1.The response frequency is an average value.
Measurement conditions are as follows: standard sensing object, a distance of twice the standard sensing object, and a set distance of half the sensing distance.

*2.Incorrect operation may occur if there is a large temperature difference between the Sensor Head and the Amplifier Unit.

Caution: In the interenst of product improvement, specifications are subject to change without notice.
