The ratio of the luminous flux of the penetrating object to the luminous flux of the incident object is the transmittance of the object, expressed as a percentage. DR81 transmittance meter is mainly used to measure the visible light transmittance of various glass, plastic, film and transparent or translucent materials, this instrument is made of imported components according to the optical principle, its operation is simple, the measurement is accurate, the size is small, easy to carry, especially suitable for on-site measurement.
On-site measurements in automotive manufacturing and inspection, glass products, aerospace and other industries.
Light transmittance measurement of protective film, PC, acrylic and other plastic products.
Measurement of light transmittance of other transparent or translucent materials.
(Note: Printed, frosted, and milky white materials are not suitable for this machine measurement)
Split transmittance meter, simple operation, fast measurement speed, good sensitivity, high measurement accuracy
There are two test modes: single and continuous (CONT INUE) measurement modes
There are four statistical functions: maximum value (MAX), minimum value (MIN), average value (MEA), and number of measurements
Large storage capacity for 800 measurement data
Connect to a computer for communication, read out the stored data for saving or printing (applicable to the host with communication port)
Automatic calibration and manual calibration of the instrument at start-up
Beep indication during operation (single measurement method)
Large LCD with backlight, low Voltage indication
Manual/automatic shutdown function
