1. Introduction
The Linshang LS301 Thermal Shielding Glass Solar Film Temperature Meter is a specialized instrument designed to measure real-time temperature values and inspect the insulation effect of various materials such as solar film, film glass, transparent glass, and thermal insulation coatings. It provides an intuitive and easy-to-operate method for comparing the thermal insulation properties of different materials.
2. Key Features
- Simultaneous display of real-time temperature values and insulation rates for tested materials.
- Equipped with two independent test boxes, each measuring 200mm x 160mm.
- Features sophisticated imported temperature sensing probes, sensitive to subtle temperature changes.
- Utilizes genuine 150W Philips infrared lamps for effective insulation testing.
- Intuitive operation for comparing thermal insulation effects.
3. Setup
- Unpacking: Carefully remove the LS301 meter from its packaging. Inspect for any signs of damage.
- Placement: Place the meter on a stable, flat surface in a well-ventilated area. Ensure there is sufficient space around the device for proper airflow.
- Power Connection: Connect the power cable to the 220V AC power supply.
- Initial Power On: Turn on the device. The display will show the environmental temperature and a 0.0% insulation rate for both sides when no sample is present.
4. Operating Instructions
The LS301 is designed for straightforward operation to demonstrate and measure thermal insulation properties.
4.1 Pre-Test Conditions
- Before placing any test material, ensure that the temperature difference between the two test boxes does not exceed 2°C.
- The black probes inside the test boxes are for testing insulation. The width of the slot for samples is 20mm.
4.2 Testing Procedure
- Prepare Samples: Obtain the materials you wish to test, such as laminated glass, white glass, or solar film. The maximum test glass size is 200mm x 160mm.
- Place Samples: Carefully insert one piece of laminated glass into one test box and a piece of white glass (or another comparison material) into the other test box.
- Observe Initial Readings: The instrument will immediately display the insulation rate for each glass sample. The temperature data will flash, indicating that the device is ready for measurement.
- Start Test: Press the "Test" button (labeled "复位/测试" on the device). The two infrared lights will turn on, and the temperature inside the boxes will begin to rise. The thermal insulation data will be locked on the display.
- Feel Temperature Difference (Optional): You can carefully feel the temperature difference between the two test boxes directly with your hands to experience the insulation effect.
- Test Duration: The entire test cycle lasts for 1 minute. After 1 minute, the two infrared lights will automatically turn off, and the cooling fans will switch on to cool down the test boxes.
- View Results: The instrument will lock the final data after the test is finished.
- Reset: Press the "Reset" button to unlock the data and prepare for a new test.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the instrument. Do not use abrasive cleaners or solvents.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Handling: Handle the instrument with care to avoid dropping or impact, which could damage internal components.
6. Troubleshooting
- No Power: Ensure the power cable is securely connected and the power outlet is functional. Check the power switch.
- Inaccurate Readings: Verify that the test samples are properly seated in the test slots. Ensure the ambient temperature is stable and within the operating range.
- Insulation Rate Not Displayed: Make sure the test samples are placed before pressing the "Test" button. If samples are inserted after the test starts, the insulation rate may not be calculated correctly.
- Temperature Difference Exceeds 2°C Before Test: Allow the instrument to stabilize in the ambient environment for a longer period until the initial temperature readings are close.
