1. INTRODUCTION
Apollo 1.0 and Apollo 2.0 are instruments for accurate measurements of
UV-A irradiation and visible illuminance. Extra engineering eort is taken to
make an accurate measurement of visible light emission from a UV-A lamp
by incorporating a superior bandpass lter containing only non-uorescent
lters. e instrument provides fast measurements as it oers 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 compact
size. Apollo 1.0 and Apollo 2.0 are traceable to NIST (USA’s National Institute of
Standards and Technology). In addition, Apollo 2.0 complies with the ISO 3059
standard.
Sensor measurements and transmission of the data is done via Bluetooth. e
wireless sensor enables the user to measure from a distance of up to ve meters
(16feet). is feature ensures that the sensor unit is stable, and no movement
occurs from connecting cables during measurement. Each sensor unit has both
the UV and white light sensors incorporated.
Apollo 1.0 and 2.0 come as a single kit or as a double kit. e 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. Please note that Aerospace companies that are audited by Nadcap
must send in both the reader and the sensor for calibration.
