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.
