KFK photometer small-sized
KFK photometer small-sized The KFK photometer is designed to measure spectral directional transmittance coefficients (SDCTs), optical density of transparent liquid solutions of substances in certain areas of the wavelength range, as well as to determine the concentration of substances in solutions after preliminary calibration of the photometer by the consumer. The photometer is developed on a modern element base, has high technical and operational characteristics, modern aesthetic design and is intended for performing chemical and clinical analyzes of solutions. Advantages: data exchange of measurement results is carried out using a computer via the USB 2.0 interface and an exchange program that allows you to visually observe the measurement results stored in the photometer archive on the monitor screen; has high stability; wide spectral range; works in 2 modes: by factor and standard; four types of cuvettes: rectangular with stroke lengths of 3, 10, 30, 50 mm, funnel-shaped drain with an internal diameter of 10 mm. The photometer is used: in agriculture - chemical analysis of water, feed, soil for the content of nitrates, phosphates, magnesium, manganese, potassium; in environmental services - to conduct more than 30 different types of water tests; in the food, chemical industry, geology, biochemistry.
