产品描述
This series of products is one of the commonly used analytical instruments, factories, mines, hospitals, schools and research units in the laboratory, general chemical energy in the visible light range of colorimetric analysis test. If the increase in 0.5A, 1A, 1.5A piece of any piece of extinction, but also for the colorimetric determination of high content.
A large number of application shows that this kind of instrument is the most reliable quality, the most widely used popular models, is listed as a variety of test procedures and the textbook standard instrument.
This series of products with automatic door light, localized gain adjustment circuit is particularly reliable, T, A direct reading, convenient operation.
Structure:
The instrument is composed of a light source lamp, adjustable voltage, monochromator, cuvette holder, photoelectric tube cassette (electronic amplifier), stable voltage device and power transformer etc.. The optical part is the self collimation optical path, single beam method, using tungsten lamp as light source.
