※
9 The irradiance measurement range is a range that can be measured instantaneously, not a range
that can be continuously measured.If the light receiving part is continuously irradiated with
UV light, the internal optical components may deteriorate and the irradiance may be displayed lower
than the original value. Therefore, we recommend that you calibrate regularly.
