Please read this manual carefully before using and reserve it for reference.

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.

Structure

The picture above is the side laser marking text

• “OFF/ON”, power switch
• “USB” , the type-C power socket
• “940nm, Full IR and 1400nm”, dial switch for three different IR wavelength

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, TSER 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 and TSER measurement is not valid on window film or colored glass

Features

1. Parallel light design, Large color LCD display.
2. Total Solar Energy Rejected (TSER) and 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.

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.

Packing List
