E3S-R
Light Level Change Rates with Various Transparent Objects (*1)
The following are the permeation rates of various transparent objects on condition that a permeation rate of 100 means that there is no object within
the sensing distance of the E3S-R. The permeation rate of any type of object sensed by the E3S-R must be as low as possible for reliable detection
of the object. Before using the E3S-R, be sure to test it on samples to make sure it can detect the items reliably.
