Sensors are usually constituted by the three electrodes, of which the most important is the working electrode. It is usually in a catalytically active l, such as: platinum, its spraying in a hydrophobic membrane made of breathable, however. The measured gas diffusion through the porous membrane on which the oxidation or reduction reactions. The nature of its response to the working electrode potential and theEconomical Seriesthermodynamic analysis of gas (redox) the nature of the. Participate in redox reactions in response to the electronics, the flow (reduction) or out (oxidized) working electrode, through the external circuit as the sensor output signal. In order to carry out redox reactionsrappaport stethoscope, the thermodynamic potential of the working electrode is a very important factor. Reference electrode in electrolysis is working to provide a stable electrode potential is designed. Reference electrodeDeluxe Series is usually in need of protection, so that is not exposed to the sample gas, so that the thermodynamic potential of reference electrode to always have the same value to maintain stability. In addition, the reference electrode does not allow the current needs of the second electrode, and its main is to allow electronic accessPalm Type sphygmomanometerto or out of the sensor inside. Control of electrode potential and the signal current into a voltage signal of the circuit termed constant potential circuit (or constant potentiometer). The work of the working electrode signal to be converted by the U2 op-amp voltage signal. Circuit voltage while maintaining the working electrode soAneroid TYPE that the value is in its bias Vbias. Reference electrode potential with a carefully selected input voltage Vbias relatively stable, the U1 op ampwall type sphygmomanometer circuit in the electrode produces a voltage signal, which is precisely the size of the working electrode to produce a current equal and opposite current signal. ConstantPALM TYPE blood pressure monitorpotential circuit while the working electrode and reference electrode to maintain a constant between the potential difference (voltage). Laser light source, the concentration of particulate matter conversion factor from the impact of color, built-in optics scattering, to ensure high stability. Instrument design particlesPalm Type sphygmomanometerthat can be replaced cutter realized the PM10, PM5, PM2. 5, TSP cutting a variety of particle separation compatible. Filter sampler to achieve a continuous monitoring of dust concentrationsphygmomanometer with stethoscopecompatible with the membrane sample, can analyze the collected particulate matter composition and thus get the mass concentration conversion coefficient K value. Constant current controllerblood pressure monitordesigned to ensure constant sample flow rate, cutting the curve is correct. Air curtain with a special protection to avoid dust core component of the instrument -wall type blood pressure monitorthe pollution of the optical system, to ensure high reliability of the instrument through the computer software automatically adjust the zero to improve the measurement precision, convenient to useStandard sphygmomanometer....
