Ultraviolet Sensors and Meters
The Ultraviolet Sensor measures the total ultraviolet radiation between 250 and 400 nanometers, in µmol m-2 s-1.
EFFECTS ON OUTPUT
COSINE RESPONSE
Some of the radiation coming into a Ultraviolet Sensor at low angles is reflected, which causes the reading to be less than it should be. The cosine-corrected head helps to capture radiation at low angles. The cosine error for typical applications is less than 10 %.
TEMPERATURE RESPONSE
The temperature response is about 0.1 % per degree Celsius. This temperature error is insignificant for most applications.
LONG-TERM STABILITY
The output of all radiation sensors tends to decrease over time as the detector ages. Our measurements indicate that the average decrease of the sensor is about 1 % per year. We recommend returning the UV Sensor for recalibration every 2 years.
