UV AB & Illuminance Meter XAR-UL02

XAR-UL02 is a precise meter that measures ultraviolet UVA and UVB radiation and illuminance (lux, footcandle) simultaneously in the field.

UV AB & Illuminance Meter XAR-UL02

Measurement Principle

XAR-UL02 has two types of sensors. One is UVA+B sensor, and another is illuminance photo sensor. UVA+B sensor is a schottky photodiode based on gallium nitride material to detect UVA and UVB radiation. It has the characteristics of high sensitivity and high stability.

The illuminance photo sensor is meet CIE (International Commission on Illumination) photopic spectral response. It consists of a very stable, long life silicon photodiode and filter.

 

Features

UVA+B radiation measurement:

Gallium Nitride Based Material Photovoltaic Mode

Description

Low danger from the sun’s UV rays for the average person

Moderate risk of harm from unprotected sun exposure

High risk of harm from unprotected sun exposure

Very high risk of harm from unprotected sun exposure

Extreme risk of harm from unprotected sun exposure

 

Spectral Response

1.      UVA+UVB Spectral Response

 

The peak point (calibration point) of UVA+B sensor spectral response is at 352 nm.

 

2.      Illuminance Spectral Sensitivity Characteristics

To the Illuminance photo sensor, the applied photo diode with filter makes the spectral sensitivity characteristic almost meet CIE (International Commission on Illumination) Photopic curve.
