Photo Colorimeter Model 1311 EI-OCTOVISION New µP 3 Digit Display with 8 glass filters AUTO ZERO

Microprocessor Photo Colorimeter – 1311 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 100% Transmission. The use of microcontroller has made it extremely versatile and state-of-the-art instrument. 10 mm pathlength matched test tubes are used for sample and blank. Photo Colorimeter Model 1311

The instrument operates at wavelength between 400 to 700 nm range. The use of high standard wide range glass filters covering 400 to 700 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. Photo Colorimeter Model 1311
