General Description
UV Power Meter CNC123 is a wide range spectral wavelength power meter.
It can be used for
measuring the optical power density of UV light. It is used for
-Evaluating heat-insulating property of the tint of windows, solar
films, glass and other transparent materials ;
-Measuring the power of ultraviolet radiation(260nm~380nm), gives
visual and reliable
result ;
-UV sterilization and curing;
-General laboratory use;
Parameter
1-Accuracy : ±（4 %FS ＋ 2digit） FS：Full scale
2-Infrared peak response wavelength is 365nm, range (260nm-380nm)
3-Scale: ×1 （0-1999 μW/cm2）； ×10（2000 -19990 μW/cm2,displayed value×10）
4-Size: 125mm*68mm*22mm（L*W*H）
5-Weigh: about 110g
6-9V alkaline battery，6F22
Operation
Measure the UV power of solar or UV lamp
1-Put the meter at a suitable distance, and direct the end-mounted
sensor to UV source, press the POWER key to switch on, select the
suitable range for the measurement, the value will display.
2-Measure the UV rejection of solar control film, glass etc. it will
take measuring in 2 steps.
Measuring the UV rejection of a solar film
1-Measuring the power of UV source UV1 W
2- Put the solar film in near front of the meter, measuring the
transmitting power UV2 W ,
Then UV rejection = UV2 UV1 100%-W /W
In the example, UV rejection = UV2 UV1 100%-W /W =100%-12/372 = 96.77%
Tips
1-Measuring the UV rejection, Power meter should keep in the same position;
2- Choose the suitable measure range;
3-Turn off the power when not in use;
4-When change the battery, open the rear cover, use a new 6F22 alkaline battery;
5-Keep away from corrosive material, high temperature and humidity environment.
