The infrared photometric oil measuring instrument is a high-precision analytical instrument, which adopts an integrated optical path system with reasonable optical path design, strong signal and high signal-to-noise ratio. Aluminum alloy casting base, after natural failure treatment, external power supply, injection molded shell, beautiful and generous, light in size and weight, it can be used as a portable instrument as well as a laboratory instrument.
Technical Features:
Switching power supply, wide power supply range, automatic switching mechanism between samples and reference cells, positioning, eliminating errors, and making the influence of mechanical errors approach zero cosecant mode for wave number positioning and scanning, so that the wave number positioning accuracy is less than one wave number and three wave numbers, in line with "HJ 637” does not need to make a standard curve, only a set of calibration coefficients is used to simulate the oil composition in water, and the error of measuring the standard oil of any component is less than 5%, so that the instrument is equipped with a meal fume measurement menu for the actual water sample service, completely according to the diet Oil fume emission standard GB18483 measurement of oil fume in catering industry.
Chinese menu operation, equipped with a large-screen LCD display , no need for calibration of standard samples, measurement results can be printed out, can be used independently from the computer , can be connected to a computer system for operation, the wave number can be freely compensated and positioned , and can be quantitatively measured, Qualitative analysis is also possible; the spectrum is clear and various interfering substances can be distinguished
