Yonglida UV-Integrator150 energy meter is an instrument that uses a photometric device to measure UV energy. The main sensor of the measuring instrument is on the back of the measuring instrument. The measuring range is 250-410 nanometers. When measuring, it can be directly displayed on the front of the energy meter. Read out on the display (unit: Joules/square centimeter), the UV energy meter is powered by a 36-volt lithium battery. Due to the use of a special energy-saving circuit, the battery can last for approximately 1,000 hours.

a. Turn on the ON switch, then the LCD (display) will show zero
b. Place the energy near the UV light source and aim its back towards the light source (the energy sensor of the UW energy meter is on the back)
c. Until there is a measurement display on the display screen of the V energy meter, for example, 800 mJ/cm2. (800mj/cm2)
d. Record the value on the display screen or use it as quality control and experimental parameters, and turn off the energy meter switch (0FF)
