Linshang LS301 Solar Film Meter

Specifications

Manufacturer: Shenzhen Linshang Technology Co., Ltd.
Product: LS301 Solar Film Meter
Version: User Manual V5.04

Product Information

The LS301 Solar Film Meter is designed to demonstrate the heat-insulating properties of solar film.
It can measure the heat rejection rate and temperature value of materials.
The product features two 150W Philips infrared lamps, temperature LED for displaying current temperature, a heat rejection LED for displaying heat rejection rate, and allows for direct measurement of heat rejection rate.
It also includes a temperature comparison test to show the heat-insulating properties of different materials.
Powering On: Power the instrument by plugging into a 220V AC power source.
Reset/Test Button: Press this button to start a test when the Temperature LED flashes. The test ends after one minute.
Data Handling: Heat rejection rate data is held during testing and can be reset using the Reset/Test button for a new measurement.
The instrument allows for a temperature comparison test using two independent infrared lamps and temperature probes. Follow these steps:
Place two samples in the left and right test boxes of the instrument.

FAQ

Q: How do I reset the data hold during testing?
A: Press the Reset/Test button to release the data hold and enter the waiting status for a new test.

Product Introduction

The solar film meter is designed to demonstrate the 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 properties of different materials.

Standards for the product: JJG( 苏)99 2010 Digital Thermo hygrometers

Parameters

Temperature measurement accuracy for a single side: ±0.5℃
Heterogeneous temperature degree of two infrared lamps: 2℃

Operations

There are three testing statuses of the instrument: waiting for testing, being tested, 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 tested.
Being tested: 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 the status of waiting for testing.

Powering on

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

Reset test button

When the “Temperature” LED flashes, the data on the LED refers to the actual temperature in the current test box. When the gap in actual temperature between the 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 the left and right test boxes fall 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.
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.

Temperature comparison test
Two independent infrared lamps and temperature probes are available for instruments, which enable the temperature comparison test to measure the heat- insulating properties of two different film mounting glasses. See the following for test procedures:

Place two samples respectively into text boxes in the left and right sides of the instrument
Press “Reset/test” to light up two infrared lamps and start the test. The temperature in the left and right boxes begins to climb up.
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.
The temperature difference in the left and right boxes manifests different thermal properties between two samples.

Heat rejection comparison test of solar film

The solar film meter 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.

Precautions

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