Automation of Process of Measuring and Control of Technological Water

For determination of fluoride in the different objects of environment and technological solutions the greatest interest presents by itself a crystalline hard membrane electrode, the features of that are a small inertance, protracted term of work, chemical stability in relation to many acids and lyes, Nernst character of dependence of electrode function, that is kept in the interval of a few orders of change of activity of fluoride, absence of influence of oxidants and repairers that are in solutions

The research of piezoelectric transducers for ultrasonic medical systems

Piezoelectric transducers are widely used in the medical systems, special permanently in ultrasonic inhalation devices for spraying of drugs for the treatment of upper respiratory tract and lungs. The devices are simple enough, convenient and reliable in operation. It was developed a research installation for the research and parameters optimization of piezoelectric transducers that can be used as nebulizers, and aerosol cloud formation from an aqueous solution of drugs

A Device for Successive Injection Analysis

In practice of liquid environments parameters control of chemicaltechnological processes and quality of technological water a wide use is found measuring in the running analysis methods. In the process of development of the informatively-measuring checking of quality of technological water systems the task of device planning was distinguished for realization of injection analysis directly for the ecological monitoring of environment and automation of control and management chemical-technological processes

Calibration of ionometric transducers for information-measuring systems and automatic control systems in real mode

Currently, there are a number of ways ISE calibrations, each of which depends on several factors: the amount and nature of the sample, frequency analysis, metrological characteristics and electrode-active properties of the material of the electrodes themselves. However, these calibration methods have limitations when used in the flow-injection analysis method (FIA)

The Flow-Injection Device for Remaining Chlorine in Technological Water

The flow and flow-injection methods of lead through of analysis are effectively used for development of automatic control systems (ACS) of technological water. The creation ACS of remaining chlorine conducted in the direction of diminishing of physical devices specifications, increase of analysis automation, diminishing of their production and exploitation cost
