Tridinamika, Indonesia’s leading dealer of test and
measurement equipment, offers a whole range of particle counters for various applications. These instruments
mainly detect as well as count particles in different tested substances.
How Do
Particle Counters Work?
Particle counting is possible through any of three routes –
scattering of light, obscuration of light and direct imaging. Particles are
illuminated by high-intensity light, normally halogen light or a laser, as they
pass through a detection vessel. When light is redirected, it is captured by a
photo detector. In direct imaging, illumination is provided by halogen light
while a high magnification camera captures images of the traversing particles. Computer
software is then used to analyze the data. In obscuration or light blocking,
loss of light will be detected. The device will measure how much light is
scattered and blocked, and the particles are counted.
Types of
Particle Counters
There are three types of particle counters – aerosol, liquid, and solid. Aerosol particle counters assess the
quality of air by analyzing suspended particles. The purpose is usually to know
how many particles are present in a building or in ambient air, or to obtain a
precise evaluation of a controlled environment’s level of cleanliness. Liquid particle counters determine the
quality of fluids, like cleaning solutions and drinking water, or the
cleanliness of sensitive items such as injectable drugs. Solid particle counters determine
the amount of dry particles for various industrial applications, such as
assessing the size of rocks that have been put under a crusher in a mining
quarry environment. Explore these particle counters and more at Tridinamika.
