LS301 solar film tester

Instruction manual V2

The LS301 solar film tester is designed to demonstrate heat-insulating property of the

solar film and can be used to measure the heat rejection rate and the temperature value.

Two 150w Philips infrared lamps.

"Temperature" LED to display the current temperature value.

"Heat rejection" LED to display the heat rejection rate of the measured material.

Directly measure the heat rejection rate of the material.

Temperature comparison test to intuitively show heat-insulating property of

different materials.

I: LS301 parameters

1. Temperature measurement accuracy for a single side: ±0.5℃

2. Heterogeneous temperature degree of two infrared lamps: 2℃

3. Temperature measuring range: -55℃---- +125℃

4. Time for temperature test: 1 min

5. Infrared ray: the peak wavelength is 950nm

6. Measuring accuracy of heat rejection: ±2%

7. Size of the testing glass: 200mm×160mm

8. Gross weight: about 12 kg.

9. Dimensions: 340mm×200mm×400mm(L*W*H)

10.Power supply: 220V AC

II: Operations

There are three testing statuses of the instrument: waiting for testing, being testing and

end of testing

Waiting for testing: the temperature data flashes to indicate waiting for testing. Under

this status, press the button to enter into the status of being testing.

Being testing: The heat rejection data is held, the temperature data stops flashing,

and the infrared lamps are lit up. After the 1-min test ends, the infrared lamps lights off

and the instrument automatically enters into the status of end of testing.

End of testing: The test results for heat rejection and temperature are held. Press

"Reset/test" to release the data-hold and enter into the status of waiting for testing.

1. Powering on

Power the instrument on by plugging into 220V AC power source.

2. "Reset/test" button

When the "Temperature" LED flashes, the data on LED refers to the actual

temperature in the current test box. When the gap in actual temperature between left and

right test boxes falls within 1 degree, the test data becomes more accurate.

When the "Temperature" LED flashes and the gap in actual temperature between left

and right test boxes falls within 1 degree, press the button "Reset/test" to begin the test,

with both infrared lamps lit up and the temperature in left and right test boxes climbing up.

The test will end after one minute. At that time, the infrared lamps go out, and the

temperature values obtained from the test are displayed respectively on the temperature

LEDs in left and right test boxes and remain unchanged.

Press the button "Reset/test" again to release the data-hold. The "Temperature" LED

flashes and the data in flashing is the actual temperature in the current test box.

3. The data of the heat rejection rate will be always held after the temperature test begins

and can be held off by resetting. The new measurement can be undertaken only after

releasing the data-hold.

III: Temperature comparison test

Two independent infrared lamps and temperature probes are available for LS301,

which enable the temperature comparison test to measure heat-insulating property of two

different film mounting glasses. See the followings for test procedures:

1.Place two samples respectively into text boxes in left and right sides of LS301.

2.Press "Reset/test" to light up two infrared lamps and start the test. The temperature in

left and right boxes begins to climb up.

3.The test ends after one minute. Then, the infrared lamps go out, and the temperature

values obtained from the test are displayed respectively on the temperature LEDs in

left and right test boxes. Such values remain unchanged and cannot be reset until

the button "Rest/test" is pressed.

4.The temperature difference in left and right boxes manifests different thermal

properties between two samples.

IV: Heat rejection comparison test of solar film

LS301 solar film tester can directly test the heat rejection rate of the sample. In the

status of "Waiting for testing", insert the sample into the test position and the

corresponding "Heat rejection "LED directly displays the heat rejection data of the sample.

V: Precautions

1．After the test ends, the fan will automatically start for cooling and stop after four

mins.

2．As the test data remains unchanged after the test ends, it's necessary to press

again the button "Reset/Test" to reset the heat rejection data and temperature data.

After resetting, the temperature data will flash and the displayed data is the actual

temperature in the text box.

VI: Standard packing list
