Filter Photo Colorimeters

Filter photo colorimeter, Models 321E and 322E with 8 and 5 glass filters respectively are offered. Output is available on a 125 mm mirror scale ammeter for an accurate reading both in terms of optical density and transmission (%T). High standard glass filters covering complete visible range of 400-700 nm mounted on rotating disc, 6.5 V tungsten lamp as a light source and highly sensitive photocell makes the instrument rugged, accurate and economical in maintenance. A small sample size of 1 ml makes the operation cheap and economical. Provision has been made to switch on the light source only when needed, thereby increasing the life of the photocell tremendously. The instrument is extremely useful for quantitative estimation of several chemical substances including blood chemistries in chemical/clinical labs, pharmaceutical industries, medicine plants, water treatment plants, agriculture universities and textile industries. The range of product includes microprocessor pH system, digital pH meters, spectrophotometer, digital photo colorimeters, water and soil analysis kit, TDS meters, DO meters, conductivity meters, microprocessor KF titrimeter, digital turbidity meters, telethermometer, temperature indicators/controllers, etc.
