Prototype of modular multiple sample bacterial growth monitor with termostabilised measuring chamber and increased sensitivity
Abstract
Stand-alone prototype of laboratory device for haze measurement of liquids was developed. Hazemeter measures elastic light scattering intensity at the angle 11o to the incident light beam and compensates it to the transmitted light intensity with enhanced sensitivity +- 0.001 ppm.
Device has display and keyboard, basic functions are controlled by a microprocessor unit. Hazemeter is equipped with built-in magnetic stirrer.
Measuring sample chamber is thermostabilised at constant temperature (+/- 0.2 oC) by a peltier type unit. Special SW (OS Windows) enables user to perform microorganism growth measurement and evaluation..
Prototype enables to measure simultaneously up to eight samples.
