Car Window Tint Meter Calibration Specification

From:Linshang Time:2019/10/11 10:39:00 Browse:31
The “Calibration Specification for Car Window Tint Meter” mainly introduce the stipulations on measurement characteristics, calibration conditions, calibration items and calibration methods.

     The car window tint meter for automobiles is mainly used for the detection of the transmittance of automotive film glass and is mainly used for vehicles, traffic police brigades and other institutions. Therefore, the calibration specifications for car window tint meters are quite strict. A good car window tint meter can meet the standard of National Institute of Metrology and Quality Testing for calibration. Below we will give a brief understanding of the "Corrosion Specifications for car window tint meter".
     The "Calibration Specification for Car Window Tint Meter" mainly requires measurement characteristics, calibration conditions, calibration items and calibration methods, expression of calibration results and time interval.
     In the calibration conditions, environmental conditions, supporting equipment, filters, and spacers are mainly required. The ambient temperature in the calibration environment is specified as (0-40) ° C and the relative humidity is ≤ 85%. The supporting equipment uses standard instruments. The filter uses a standard neutral filter and requires a transmittance of approximately 50%, 70%, 80%. The transmittance values were weighted by the measured transmittance values in (400-760) nm. The extended uncertainty of the transmittance is ≤0.6%. The spacer is 8mm thick.
     The drift amount is specified in the "Optometer for Car Window Tint Meter": a neutral filter having a transmittance of 70% is inserted between the light source component of the car window tint meter and the sensor. The recorded values were observed every 5 minutes and observed 3 times in succession. The difference between the maximum and minimum values between the three indications is the amount of drift.
    A calibration certificate is usually issued for the expression of the calibration result, and the revisiting time interval is recommended for one year.
     A complete "Calibration Report" shows the main information: customer name, address, measuring instrument name, purpose, model, factory number, manufacturing unit, calibration basis, calibration main measurement standard device information, calibration main standard information, additional instructions, calibration results. For example, Linshang LS110 is a car window tint meter that complies with the national " Calibration Specification for Car Window Tint Meter". The calibration report is as follows:

calibration certificate

    Linshang LS110 automotive car window tint meter not only can be used to detect the light transmittance of automotive glass, but also can be used for the transmittance test of glass curtain wall and other scenes. The instrument is a car window tint meter which adopt the split design and there are also features such as wireless, large screen, etc. It is the best choice for you to test the transmittance of various glass materials.
