PORTABLE MULTI-WAVE PHOTOMETER FOR ANALYSIS OF LIQUIDS

摘要

The utility model relates to analyzing equipment and can be used to analyze various samples, in particular, for screening the population in medium and small laboratories. A portable multi-wavelength photometer for analyzing liquids contains a housing, an installation unit for placing the test samples, a step drive for moving the installation unit, a readout unit containing emitters and photodetectors located on different sides of the installation plane moving plane, a visualization, control, and indication unit. The device has dimensions of not more than 150 × 75 × 50 mm and a mass of not more than 0.4 kg; the case has a lightproof coating; the installation unit of the device has a carriage for placing standard single-row 8-beam strips with microtubes on it; the device has one step electric drive for moving the carriage; the reading unit is in a stationary position, it contains three optical pairs of photodetectors and LEDs with wavelengths of λ 340 nm, λ 450 nm, λ 505 nm, coaxially arranged in pairs opposite each other, relative to the plane of movement of the carriage, and the distance between the axes of the optical pairs is equal to the distance between microtube axes in a standard single-row 8-hole strip; The device has an LCD display with a touch keyboard and a lithium-ion battery connected to the board with a micro-USB controller. The technical result is the creation of a portable photometer. 2 ill.
