Apollo 3.0 is an instrument for precise measurements of UV-A irradiation and illuminance. Extra engineering effort is taken to make an accurate measurement of visible light emission from an UV-A lamp by incorporating a superior bandpass filter containing only non-fluorescent components. The instrument provides fast measurements as it offers autoranging and concurrent measuring of visible light and UV-A irradiation. It is ergonomic and easy to use due to its lightweight chassis, a wireless sensor unit and its compact size. Apollo 3.0 is traceable to NIST (USA’s National Institute of Standards and Technology) and complies with ISO 3059. For Apollo blue, the UV-A sensor is replaced by a blue light sensor which is in compliance with CEN/TR 16638.
Apollo 3.1 offers the possibility to measure luminance in cd/m² or fL using a specially designed tube. The application range is focused on extensive illumination fields such as screens for radiographic testing. Any Apollo meter can be upgraded to measure luminance by purchasing an upgrade package, including calibration at Labino.
