About the value of each manufacturer's UV illuminance meter
Even if measured under the same UV irradiation conditions, the values indicated by each UV sensor and manufacturer may differ depending on the light-receiving characteristics and calculation formula of the device. We recommend the use of an illuminance meter of the same manufacturer to calculate irradiation conditions.
