LINSHANG LS301 Instruction Manual

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,
