The c-meter is a conductivity-meter for two- or mono-component developers that are qualified for magnetic polarisation. It measures conductivity from the charge decay curve.Read More
The M-meter measures the magnetic hysteresis loop of powder-material, for example magnetic toner, carrier, ferrite powder or magnetite. Several magnetic parameters can be calculated from the hysteresis loop, such as remanence, coercivity etc…Read More
The q/d-meter (former q-test) measures the charge distribution q/d in fC/µm of dry particles. The distribution provides more detailed information about the charging characteristics of the particles…Read More
The q/m auto is a fully automated measurement device to measure the charge to mass ratio of dual component developer systems (carrier + toner). The device has been developed from our manual q/m-meter device and delivers fully compatible results. …Read More
The q/m meter is used to measure the charge to mass ratio of dual component developer systems (carrier + toner) and, optionally, for mono component toner systems. The q/m-value measured in µC/g is one of the important physical properties used to characterize toner/carrier, and is used in the electrostatic printing process …Read More
PES – Physics of Electrostatic Systems
Electrostatic charge is everywhere – many technologies use it, and others need to avoid it!
Charge is affected by multiple material and environment parameters:
chemical formulation, homogeneous or mixed powders, surface properties, additives, electrical conductivity.
electrical and magnetic fields, temperature, humidity.
number and strength of collisions among the particles or against other surfaces.
The imaging process in the electrophotography is based on electrostatic charged particles, called toner.
Many other traditional and new technologies, such as powder coating, the pharmaceuticals industry, and prototyping use the physics of electrostatic charge. To improve the performance of these applications, an even better understanding of the charge and the mechanisms behind charge is necessary.
The EPPING – PES Laboratorium has over 30 years of experience in producing measurement devices for electrostatic charge. Our devices are characterized by high quality, high stability, reproducibility and reliability, which make us a competent and valuable partner to our customers around the world.
All of our devices are available in our lab for testing. We can also measure your samples as a service in our lab.
