Introduction:
Optical irradiance meter is widely used to measure the radiant power density of the light source, that is, the radiant power per unit area. The unit is ¥ìW/cm2, W/m2. This product can also be used to measure the transmittance and blocking rate of materials to light. And ambient temperature testing. The product is easy to use, accurate in measurement and reliable in quality!
Application Field:
*Solar radiation intensity measurement, optical experiment
*Light transmittance, light blocking rate, and reflectance measurement of materials
*Meteorology, medical, food, agriculture, etc.
Advantage:
1. Large measuring range;
2. High measurement accuracy;
3. Automatic switching range;
4. Measured power peak
5. It can measure light transmittance and light blocking rate;
6. With temperature test function;
7. Can save 100 sets of test data

Operation Instructions:
1. Press M key after power on to switch to mode 2
2. Align the front end probe window of the power meter with the radiation source. At this time, both A and B display the real-time power value, and ¡°A¡± flashes.
3. Press OK to calibrate and lock the power A to the total power (at this time, if you need to re-measure the total power and press OK, you can unlock A).
At this time, ¡°B¡± starts to flash, and the sample to be tested is placed between the light source and the power meter probe window, due to the covering of the measured object.
The radiation power will be attenuated. At this time, B shows the transmitted light power. The instrument automatically calculates the transmittance:
That is, the percentage of transmitted power to total power
4. The saved data can be read by pressing the R key in mode 2, and the specific operation is the same as mode 1.
5. Press H to lock the data. Press OK to save the data and release B. If you do not need to save the data.
Press H again to release B lock
6. Select the measurement rejection rate in the Mode 2 option in the setup menu: ie the percentage of blocking power to the total power
Precautions:
1. Avoid high temperature, do not exceed 70 degrees for a long time or the instrument will be damaged.
2. When not in use for a long time, remove the battery and store it in the box.
