I. Product introduction
This instrument is able to simultaneously measure and display UV, IR rejection value and visible light
transmission value. This meter is self-contained light sources and self-calibration. No manual adjustment
is needed. The users only need plug the power supply, turn on the switch and put the solar film in the
opening. The resulting performance data appear on the display.

IV. Operation
The solar film tester is used to test the UV rejection rate, IR rejection rate and visible light transmission
rate of solar films. Here are the operation steps:
1. Turn on the instrument
Plug in the power supply, keep the test slot empty, turn on the tester. Firstly, the instrument version
number and instrument model will be displayed in the screen, then, the UV and IR rejection rate data will
be displayed as "0%" and the visible light transmission rate will be 100%.
2. Measurement
Place the materials (solar film, laminated glass, etc.) into the test slot. The UV rejection rate, IR rejection
rate and visible light transmission rate of the materials are immediately displayed. The infrared rejection
rates are in response to the wavelengths (940nm, Full IR and 1400nm) selected by the dip switch and the
corresponding wavelengths are indicated in the middle of the infra-red display pointer table.
As shown in the graph below: the UV rejection rate of the sample solar film was 97.8%, the IR rejection
rate was 85.1% and the visible light transmission rate was 74.6%.

3. FULL IR and SHGC measurements
The instrument is adjusted to the "Full IR" position by flicking the dip switch, which then it can measure
the UV rejection rate, full IR rejection rate, light transmission rate and the Solar Heat Gain Coefficient
(SHGC) of the material. Full IR is the combined value of the IR940nm and IR1400nm insulation rates.
*Note: SHGC measurement is not valid on window film or colored glass
V. Features
1. Parallel light design, Large color LCD display.
2. Solar Heat Gain Coefficient (SHGC) test.
3. It can test 5 wavelengths including UV, Visible, IR 940nm, IR 1400nm, and IR full band.
4. Applicable for testing the transmittance of automotive films, explosion-proof films, architectural films,
thermal insulation films, laminated glass, etc.

5. The instrument has real-time dynamic self-calibration function, automatically calibrated after power
on.
6. Suitable for solar film performance display and exhibition, production, quality inspection, goods
inspection and other occasions.
VI. Steps and precautions for use
1. Connect the instrument to the special power supply, keep the test slot empty and switch on the
instrument.
2. Place the materials in the test slot as close to the left side of the slot as possible.
3. Turn off the power when the instrument is not in use.
4. Keep the test slot empty when self-test and self-calibration of the instrument.
5. Avoid contact with corrosive substances and keep away from high temperature and high humidity
environments.
6. If the data is not displayed as "0%, 0%, 100%" when there is no materials in the slot which is due to
the luminous efficiency of the LED light source result from long time using the instrument (the
efficiency of the LED light source decreases when the temperature of the light source increases),
please turn off the power of the instrument and restart the self-test and self-calibration. This will not
affect the measurement accuracy and normal use.
