Photocolorimeter KFK-2
Photocolorimeter KFK-2 Out of production! Closest analogue: Photometer KFK-3-01 (ZOMZ) Photoelectric concentration color meter KFK-2 is designed for measuring in certain areas of the wavelength range 315-980 nm, emitted by light filters, transmittance and optical density of liquid solutions and solids, as well as determining the concentration of substances in solutions by constructing calibration graphs. The colorimeter also allows you to measure the transmittance of scattering suspensions, emulsions and colloidal solutions in transmitted light. The colorimeter is used in water supply enterprises, in the metallurgical, chemical, food industries, agriculture, medicine and other areas of the national economy. According to operating conditions, the colorimeter belongs to category 4.2 version UHL, in the tropical version it belongs to category 4.2 version T GOST 15150-69. Normal operating conditions for the colorimeter are: ambient temperature (20±5)°С, relative air humidity 45-80°/o, mains supply voltage (220±4.4) V, 50 Hz. The kit includes: Light filters K-1, K-2 Set of cuvettes No. 2 Manba: https://www.nv-lab.ru/catalog_info.php?ID=75
