fabric transmittance apparatus

Fabric transmittance apparatus for fabric  is used to determine the total visible light transmittance of the fabric to evaluate the shading properties of the fabric and is suitable for sheet textile products such as curtains.
Test standard :
JIS L1005-2009
Fabric transmittance apparatus Test principle:
1. A light source (light bulb) is illuminated, and the light is irradiated to the photodetector of the illuminance meter;
2. Adjust the brightness of the light source to 10,000 (1X);
3. Determine the illuminance of the sample;
1: illuminance (lx) after installation of the sample; I0: no illumination of the specimen (I1: I1 / I0) × 100%, I1: Lx).
Fabric transmittance apparatus Technical Parameters:
1, power: 1000W, 220V;
2, light intensity adjustment range: ambient light intensity ~ 20000Lux;
3, illumination meter: 0.01Lux ~ 999900Lux, accuracy ± 5%.
