UV Radiometer UV 254 nm, UV 297 nm UV Irradiance Meter

The Wewon’s UV radiometer UV 254 nm, UV 297 nm adopts SMT patch technology, and selects high-precision and low-power digital chips. The UV calibration radiometer’s shell is streamlined design. The detector has been calibrated strictly for spectral and angular characteristics, with stable performance and strong applicability. The Wewon’s UV irradiance detectors suitable for ultraviolet irradiance measurement in the fields of sterilization, photolithography, ultraviolet light source, water treatment, medical treatment, breeding and so on.

The ultraviolet radiometer is a professional instrument for testing the luminous intensity of ultraviolet rays, that is, the ratio of the luminous flux obtained on the surface of an object to the illuminated area. It is mainly used to measure the radiant energy power density of ultraviolet rays, that is, the radiant energy power per square centimeter. UV calibration radiometer can be applied to monitor the intensity of ultraviolet lamp radiation in hospitals, health and epidemic prevention departments, chemical industry, electronics, food processing factories, public places, etc.

The sensitive window of the probe should be kept clean, otherwise it will affect the performance. Before the test, it can be wiped with lens paper.Precautions for Use
The number hold button should not be pressed for more than 15 seconds each time, otherwise it will affect the life of the LCD.
When checking the radiation intensity for sample testing, wait for the UV intensity to stabilize before starting the measurement. (Wait for the machine to run for 30 minutes in winter, and wait for the machine to run for 15 minutes in summer)
Ambient temperature, voltage and surrounding reflections all have an impact on the intensity of UV rays.
Avoid measuring under direct sunlight, otherwise it will affect the measurement accuracy. The UV calibration radiometer should be calibrated once a year.
If the user encounters a fault during use, please check the “Fault Checklist” carefully !
If the + – symbol appears on the left side of the display, the battery voltage is low, please replace the battery.
Do not open the probe by yourself, the internal fiber optic sensor is easily damaged, if you cause any loss, you will be responsible for the consequences.
Protective glasses do not prevent UV rays from damaging your eyes from the side.

Before shipping, Spectral, angular features are strictly corrected. Digital LCD display with backlight.UV Radiometer Features
