The Lux Illuminance Meter (order no.: 6905.001) is a hand-held instrument for measuring of illuminance in the visible range. Ultraviolet components are suppressed so that measurement (as required by ISO 3059) is possible even when the UV lamp is switched on. For ease of handling, the sensor is separated from the device.
The UV Intensity Meter (order no.: 6903.001) is a hand-held instrument for measuring the intensity of long-wave UV radiation (365 nm) and is used to check for compliance with minimum values. The photocell is removable. Direct reading in µW/cm² is unaffected by visible and short-wave UV light.
