Apollo 3.1 is an instrument for accurate measurements of UV-A irradiation in µW/cm² or W/m², white light illuminance in lx or fc, and luminance in cd/m² of fL. Since no measurement field focusing can be done, the application range is focused on extensive illumination fields such as screens for radiographic testing. Extra engineering effort is taken to make exact measurements 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 auto-ranging 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 3.1 is traceable to NIST (USA’s National Institute of Standards and Technology) and complies with the ISO 3059 standard.
Sensor measurements and transmission of data is done via Bluetooth. The wireless sensor enables the user to measure from a distance of up to five meters (16 feet). This feature ensures that the sensor unit is stable, and no movement occurs from connecting cables during measurement. Each sensor unit has both UV-A and white light sensors incorporated.
Apollo 3.1 comes either as a single kit or as a double kit. The single kit includes one reader unit and one wireless sensor unit. A double kit includes one reader unit and two wireless sensor units. As only the sensor needs to be sent for calibration, the double kit is a convenient tool so that operations are never disrupted. Apollo 3.1 offers the possibility to measure luminance. To do so, an optical tube and optionally one of two front pieces can be attached to the illuminance meter. Calibration of the illuminance meter also calibrates the luminance meter. Please note that Aerospace companies that are audited by Nadcap must send in both the reader and the sensor for calibration.
