Overview
The DR81 Transmittance meter is a professional measuring instrument of the DONGRU brand, mainly used for the measurement of visible light transmittance of various Glass, Plastic, Film and transparent or translucent materials. The instrument is based on the principle of Optical inspection and is manufactured with imported components. It has the characteristics of simple operation, accurate measurement, small size and easy portability, and is especially suitable for on-site measurement.
Features
1. Split Transmittance meter, simple operation, fast measurement speed, Sensitivity, high measurement accuracy
2. With two test modes: single measurement (SINGLE) and continuous (CONTINUE) measurement mode
3. With four statistical functions: MAX Maximum (MAX), MIN Minimum (MIN), Average (MEA), measurement times
4. Large capacity storage, can store 800 measurement data
5. Connect to the computer for communication, read out the stored data for saving or printing (suitable for the host with communication port)
6. Instrument boot auto calibration and manual calibrating
7. The operation process is marked with a beep sound (single measurement method)
8. Large LCD with backlight, low voltage indication
9. Manual/automatic shutdown function
Principle
Transmittance meters calculate light transmitance by measuring the ratio of the luminous flux transmitted through the object to the luminous flux of the incidence object, expressed as a percentage. The instrument is based on the principle of Optical inspection and is manufactured with imported components to ensure accurate measurement.
Applications
Automobile manufacturing and testing, Glass products, aerospace and other industries field measurement, protective film, PC, acrylic and other plastic products light transmitance measurement, other transparent or translucent materials light transmitance measurement
Notice
• Printing, matte surface, milky white material is not suitable for this machine measurement
• Film thickness of the measured object should be ≤ 18mm
• Ambient Temperature should be in the range of 0~ 40 ℃
• relative humidity should not exceed 85%
• Measurement object area should not be less than 10mm * 10mm
• Use three (7) alkaline batteries as power supply
