Microprocessor Based Photo Colorimeters

Photo Colorimeter (Microprocessor Based)

We offer a comprehensive range of Microprocessor Based Photo Colorimeters, which is one of the precision engineered Colorimeters available in the market. Easy to operate, these Colorimeters are commended for the excellent accuracy that these offer.  Superior quality glass filters that cover the entire visibility ranging between 400 to 700 nm are fixed on the rotating disc. A completely sensitive photo sensor, modern IC technology and various other techniques and features makes these instruments a valuable and long term investment for the clients. For carrying out the analysis, minimum 1 ml. of sample needs to be taken. For enhancing the life of the photocell, an option for switching on the light is provided.

 

Due to the accurate estimate results obtained, these Colorimeter are used in Blood Chemistries in Chemical/Clinical Labs, Pharmaceutical Industries, Medicine Plants, Water Treatment Plants and Agriculture Universities, etc.

Microprocessor Auto Colorimeter (VSI-401) is a compact and easy to operate instrument for Photo Colorimeter analysis of any concentration. The output is available on 16x2 lines alpha numeric LCD display in terms of % Transmission (%T) & Absorbance (Abs.). The use of micro-controller has made it extremely versatile and state of the art instrument.

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.

 Features:

  • Highly Accurate, Stable & Easy to Operate
  • Auto Shutter
  • Auto Zeroing Facility
  • Range 400 to 700nm.

Microprocessor Haemoglobin Meter - VSI-403 is used to determine the haemoglobin concentration in the blood sample. The measurement of haemoglobin concentration is carried out at wavelength of 530 nm. Using state-of-the-art LED technology, the green light produced is projected through the sample and measured by sensitive photo diode. The measurements are made using cyanmethemoglobin method used throughout the world.

Heamoglobin is an iron-containing protein found in the red blood cells. It enables the red cells to carry oxygen from lungs to the rest of the body and carry carbon dioxide back. The haemoglobin level indicates the blood’s oxygen-carrying capacity and can play a major role in the early diagnosis of many illnesses such as thalassemia, sickle cell anemia, leukemia, malaria and hook worm etc.

Features:

  • Direct Display in Hb. Units
  • 1 ml. Sample Volume
  • Highly Stable & Easy To Operate
  • Storage of Factor in Memory

Technical Specifications : VSI-403
