Abstract
A device for measuring the irradiation energy impinged upon a target within a fixed period, having a photo-electric receiver impacted by irradiation. Such devices have become known by the designation "Lux hour meter". They are used, e.g. for tests, by which the influence of irradiation energy on the properties of materials, e.g. textiles, shall be determined.
