Product Description

Full Color Display 0.1% Display Resolution Manual + Automatic Calibration Light Transmittance Meter


High repeatability Portable Transmission Meter for through transparent material percentage measure CT-25



Measurement Principle:
The measuring principle of the light transmittance meter is to irradiate the measured transparent substance with a light source, and the sensor respectively detects the incident light intensity of the light source and the light intensity after passing through the measured substance, and the ratio of the transmitted light intensity to the incident light intensity is light transmission. Rate, expressed as a percentage.

Product description:
* 5 channels portable transmittance meter 
* It can be applied to measure the transmittance or haze of all kinds of transparent, translucent samples with parallel plane.


Instrument Advantages :

1. Simple operation and fast to get the result, as long as the sample is placed in the test area, the test result will be displayed.

2. It can measure the transmittance of UV light, visible light, and infrared light.

3. It adopts parallel light path design, sample measurement thickness can reach 13mm

4. The instrument has a data lock function. After the test, press the HOLD key on the instrument to lock the test data, and the test sample data will still remain on the display interface after the sample is taken away.

5. Digital display, wide measuring range, high resolution.

6. Two calibration modes: Manual calibration and automatic calibration for easy usage

7. Small size and non-slip design, easy to grasp and carry for outdoor test

8. Rechargeable lithium battery, no need to take time to replace batteries.
