UV AB & Illuminance Meter XAR-UL
Measurement Principle
XAR-UL 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
High-precision detection, rapid response and operation
Display UVI (Ultraviolet Index) and UVA+UVB radiation intensity simultaneously
Display the maximum UVA+UVB radiation intensity for all-time
Illuminance measurement:
Light-measuring levers ranging from 0 to 600,000 lux, 0 to 55,740 fc (footcandle) repeatedly
Spectral sensitivity close to CIE photopic curve
Accurate and instant response
Simultaneously display the measured values of lux and fc illuminance
Display the maximum illuminance (lux and fc) for all-time
General:
Data-Hold function for holding measuring values.
Easy to read large backlight display
Only two buttons and easy to operate
Four AA Alkaline Batteries

Ultraviolet Index (UVI)
This meter displays the Ultraviolet Index (UVI) in real time. Following table list the risk of UVI level.
UVI | 0-2.9 | 3.0-5.9 | 6.0~7.9 | 8.0~10.9 | 11+ |
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.
