What is a laser particle counter?
A laser dust particle counter is an instrument used to measure the number and particle size distribution of dust particles per unit volume in a clean environment.
It can be widely used in authoritative institutions such as blood centers, epidemic prevention stations, disease control centers, quality supervision institutes, electronic industries, pharmaceutical workshops, semiconductors, optics, etc.
Or precision machining, plastics, painting, hospitals, environmental protection, inspection institutes and other production enterprises and scientific research departments.
How to use a laser particle counter?
Determine the number of test points according to the area of the clean room
And evenly distribute the test points in the clean room,
Then set the measurement time, measurement unit, flow rate and other parameters of the particle counter, and then place the particle counter on a plane at a height of 1 to 1.2 meters above the ground in the middle of the sampling point.
Finally, start to test samples one by one and record the data.
How to choose a dust particle counter?
What type of environment will the particle counter be used in? Will it be used in an ISO Class 3 clean room for routine particle counting, or will it be used in a flow-critical process?
Will this particle counter be used to certify cleanrooms and test from one location to another?
Do operators keep dust particle counters around, on critical process benches, or on carts that can be moved?
Sensitivity: Smallest particle size detectable.
Channels: This is the number of "bins" the particles are placed into, based on the calculated corresponding size of each particle. Channels are expressed in microns. For example, you might have a 4 channel particle counter. This means that particles can be counted and classified in 4 different channels. Examples of channels are: 0.1 μm, 0.2 μm, 0.3 μm, 0.5 μm, 1.0 μm, 5.0 μm…
How do dust particle counters work?
The handheld laser dust particle counter is a test instrument for the number of dust particles (ie cleanliness) contained in a unit volume of air in a clean environment. Based on the scattering phenomenon of dust particles in the beam, it is a high-tech product that integrates optics, precision machinery, electronics, and computer technology-level aerodynamics.
