RC-2100 Resistance (Coulter) Particle Counter
RC-2100 Resistance (Coulter) Particle Counter uses the Electrical Sensing Zone method, also called Coulter principle to measure the particle size. It is of high resolution since it counts particles one by one and then gives size distribution and quantity of the particles measured. Its resolution (channel) depends on the measuring accuracy of the pulse of the electrical system. It especially suitable to measure: 1. powders with high resolution requirements, or strict size distribution requirements, such as abrasive micro grits, copy powders. 2. small volume of particles in liquid suspension.
Measure powders with uniform size distribution (narrow size distribution), and measure the size and quantity of small volume of particles in water.
As shown in the figure, the aperture tube is dipped into the electrolyte. There are two electrodes separated by the aperture tube, between the electrodes an electric current flows. Particles are suspended in a weak electrolyte solution while measuring, as particles pass through the aperture, they displace their own volume of electrolyte, momentarily increasing the resistance of the aperture. This change in resistance produces a pulse that is digitally processed in real time. Analyzing these pulses enables a size distribution to be acquired and displayed in volume and diameter.
1. Traditional design with measuring unit, computer and oscillograph separated.
2. Advance pulse measurement technology, more than 8000 channels.
3. Replace the traditional mercury manometer with a pressure sensor, provides more accurate measurement and control of degree of vacuum, and higher automation.
4. Proprietary photoelectric liquid level detection technology makes the volume measurement more accurate and reliable.
5. Auto de-clogging function
