A: an overview

Principle of LS103 is the use of ultraviolet light, visible light and infrared light transparent substance being tested, sensors detect three kinds of light sources, respectively the incident light intensity and through a transparent substance being measured light intensity, light intensity to incident light intensity is the ratio of transmission, expressed as a percentage. Can test both transparent materials by UV, IR and visible light transmittance parameter.

LS103 used in glass, coating materials, organic materials, and optical transmittance of translucent substance such as paint. For single-layer glass, laminated glass (IG), foil glass, PMMA material, p-c optical performance testing of materials, and so on.

II: Instrumentation

LS103 optical transmittance measuring instrument for testing glass for infrared, visible and ultraviolet transmittance. Measurement procedures are as follows:

1: plug in the power, open the instrument power switch. In a test tank is empty, start testing and calibration, in about 30 seconds. Calibration is complete, three video display value is '100', indicating no analyte transmittance 100%.

2: to test into the test slot. Three display that can be shown on the infra-red, visible and ultraviolet transmittance.

Three: LS103

1: external dimensions: length 160mmx width 115mmx 33mm

2: cell dimensions: width 43mmx depth 76 mm

3: weight: 360 g

4: measurement resolution of visible light is 1%, UV is the resolution of 0.5%

5: infra-red measurement wavelength 950nm wavelength range (850nm-1050nm).

6:9V AC/DC power supply, portable external lithium battery pack power supply can also be used.

IV: characteristics of the instrument

1. the auto-calibration function, automatically after power on calibration and 100% transmission, no manual calibration.
2. fine aluminium alloy shell with high brightness digital display, wide perspective, especially suitable for show, used in the exhibition.
3. simple operation, measure quickly, just to test into the test slot, along with three test results immediately.
4. the device comes with light sources and sensors, measurement results are not subject to external environmental impacts.
5. adopt imported high quality light sources and sensors, high measuring accuracy.
6. adopt industrial singlechip and components, stable and reliable instrument for sustainable work.
7. suitable for all kinds of glass display, rapid test factory shipments, buyer inspection and many other occasions.
8. equipped with optional accessories: portable external lithium-ion battery pack, and a dedicated portable suitcase.

Five: attention

1. the instruments connected to the power supply, open the instrument switches;
2. start of self-checking and self-calibration, for about 30 seconds;
3. when the data show three window is 100, self-checking and self-calibration completed;
4. to test into the test slot, cell analyte close to the left;
5. three display window that can be shown in ultraviolet, visible and infrared transmission;
6. the instrument when not in use, turn off the power;
7. when on instrument testing and calibration, test the tank must be empty, otherwise the calibration cannot be;
8. avoid contact with corrosive materials, far away from high temperature and high humidity environment.
9. when used continuously for a long time, due to the efficiency of LED light sources (LED light source temperature, efficiency) causes can lead to three Windows data cannot be displayed as 100, please power off the instrument, post again and self-calibration, and does not affect the measurement accuracy for normal use.
