HM-600 digital black and white density meter, is a high-precision instrument developed by Kedian company through a large number of tests, small size, light weight, easy to carry, the use of microcomputer control, with easy operation, high accuracy, good stability and other characteristics.
HM-600 digital black and white transmission density meter, the use of AC modulation light source, synchronous reception detection technology, the use of computer control and data processing, so as to greatly improve the ability to resist optical and electrical interference and temperature stability.
HM-600 digital black and white transmission density meter, the factory has been strictly debugged and inspected, after the user turns on, only need to press the zero button, the formal test can be carried out. Random standard density tablets for users to compare and verify.
HM-600 digital black and white transmission density meter, which can measure the transmission density within 4.5D, also has reference value for more than 4.5D, and is a satisfactory instrument for the quality analysis of X-ray sheets such as pressure vessels, hulls, chemical industries, bridges, etc.

HM-600 Digital Black and White Transmission Densitometer is an instrument used to measure the amount of light transmitted through transparent materials (such as a soft sheet base) to determine the amount of light absorbed by the surface, which is mainly composed of an illumination system, a light acquisition and measurement system, and a signal processing system. The AC modulated light source is used to provide a stable light source with a certain quality, and the amount of light passing through the tested negative is received through the photoelectric sensor, and converted into an electrical signal, and the signal processing is completed and sent to the single-chip microcomputer, and finally the density value of the tested negative is displayed on the display.
