We offer a comprehensive range of Digital Photo Colorimeter, which is one of the precision engineered Colorimeters available in the market. Easy to operate, these Digital Photo Colorimeters are commended for the excellent accuracy that these offer. We also offer Filter Photo Colorimeters that are made in accordance with ISO standards. Results for the Analog Colorimeters are obtained in the terms of %Transmission (%T), Absorbance (Abs.). 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 Digital Photoelectric Colorimeters are used in Blood Chemistries in Chemical/Clinical Labs, Pharmaceutical Industries, Medicine Plants, Water Treatment Plants and Agriculture Universities, etc.

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.
