Microprocessor Photo colorimeter

タイトルまたは説明

Microprocessor Photo Colorimeter – ***1 is a compact and easy to operate instrument for Photo Colorimeter analysis of any concentration. The output is available on a 3 digit seven segment red LED display in terms of %Transmission (%T), Absorbance (Abs.). This instrument has the facility for auto zeroing of Absorbance and setting **0% Transmission. The use of microcontroller has made it extremely versatile and state-of-the-art instrument. *0 mm pathlength matched test tubes are used for sample and blank.

The instrument operates at wavelength between **0 to **0 nm range. The use of high standard wide range glass filters covering **0 to **0 nm in the monochromator gives extremely good results. The filter setting is controlled by a rotating disc having 8 filters. An automatic shutter is provided to stop the light reaching the sensor, when test tube is not inserted in the tube holder. This increases the life of sensor tremendously.
