It has been called the 'horn', the 'megaphone', the 'funnel', and even the 'big sucky thing'. Occasionally it is called a sample probe.
Officially, it is an isokinetic sample probe.
Isokinetic means that in a laminar flow area, the air flows in and around the probe without creating any turbulence.
To understand why this is important, we need to understand a fundamental difference between micro and macro particles. While 5 µm particles may seem infinitely small when we consider that our hair is 70 µm to 100 µm in diameter, 5 µm particles exhibit surprising inertia compared to submicron particles. If one were to sample without a sample probe, 5 µm and larger particles would have to be very close to the inlet before they would be pulled over to the inlet. However, the inlet would be surrounded by turbulence, and the turbulent air would repel particles that were being pulled over to the inlet. So, without an isokinetic sample probe, we lose 5 µm particles that should be counted, whether we are sampling in laminar flow or turbulent flow.
The isokinetic sample probe has a wide opening that captures air that belongs to the sample without creating turbulence. The 5 micron particles flow into the opening and are then funneled down into the tubing that connects the probe to the particle counter's inlet. Particles belonging to the sample are thus drawn in.
However, due to the inertia of 5 µm and larger particles, there is a significant loss of 5 µm particles in the transport tubing. Some have tried sampling without a probe, but they are just exchanging a loss of 5 µm particles in the transport tubing for a loss of 5 µm particles for a lack of a wide enough opening to entrain the 5 µm particles; only 5 µm particles in a narrow cone above the inlet will enter the particle counter.
Some have used a couple of inches of tubing to place the probe directly over the inlet. While this entrains particles into the sensor, it raises another, more noticeable problem. Whether sampling with a bare inlet or sample with only a couple of inches of tubing to support the sample probe, light has a direct path to enter the sensor cavity if the sensor is directly under a fluorescent light fixture while sampling. This is a problem, because modern ballasts turn the light off and on in the kilohertz range, producing a pulse with a width that is about the same that a particle produces when it passes through the laser beam. This makes it impossible to filter electronically. But we have a solution for that.
Climet gives the customer the choice between the default standard stainless steel probe with transport tubing or a light blocking isokinetic probe that fits directly over the inlet. The probe has an aerodynamic light blocking element that allows air to flow around it, and has been verified against a probe without a light blocking element to verify that the light blocking element does not take out 5 µm particles by impaction. The probe with transport tubing is needed in applications where the particle counter cannot go, such as sampling in a clean hood (The particle counter's exhaust would produce turbulence, resulting in high counts, if placed in the hood). For applications where sampling is made from a cart, the light blocking probe is a better choice. For customers with both applications, a second probe can be purchased at a lesser price when the particle counter is purchased.
Probes with transport tubing should be pointed towards the filter when in a laminar flow area. In not laminar flow areas, the probe should be placed at work height and pointed upwards. Pointing the probe upwards allows the particles to float down into the probe. If the probe were in a horizontal position, 5 µm and larger particles will float past the probe due to their inertia and never become part of the sample.

A particle counter is an instrument that uses the scattering principle of light to count dust particles. Light scattering is related to particle size, particle refractive index, light wave wavelength and light absorption characteristics of particles. However, as far as the intensity of scattered light and particle size are concerned, there is a basic rule that the intensity of scattered light increases as the surface area of the particles increases. Thus a certain flow of dusty gas is passed through an intense light, and the particles emit scattered light, which is projected onto a photomultiplier tube through a concentrating lens to change the light pulse into an electrical pulse, and the number of particles can be obtained from the number of pulses. The particle diameter can be derived from the intensity of the scattered light as a function of the particle diameter. This is the basic principle of the light scattering particle counter.

Precautions for particle counter in daily use and maintenance
1、Do not start the dust particle counting instrument when the inlet tube is covered or blocked.
2、The laser particle counter should be used in a clean environment to avoid damaging the laser sensor.
3、It is forbidden to extract gases containing oil and corrosive substances, and do not measure mixed gases that may produce reactions (such as hydrogen and oxygen). These gases may also produce explosions in the counter. Measure these gases need to contact with the manufacturer for more information.
4. Do not sample compressed air without high-pressure decompression equipment (such as a high-pressure diffuser), as all particle counters are designed to operate at an atmospheric pressure.
5, Water, aqueous solutions or other liquids should not enter the sensor from the pipeline.
6, when connecting an external printer or connecting an external temperature and humidity sensor, the counter needs to be turned off first; when performing printing operations, the printer must have print paper, otherwise it will damage the print head.
7、Without professional knowledge and skills training and technical management of professional education staff can not carry out the actual operation and maintenance.
8、When taking samples, avoid taking samples of the gas discharged from the counter itself or the gas contaminated by the counter.
9、When handling the equipment, it must be carefully transported and handled, and should be moved lightly and placed gently, and less affected by vibration and impact. Especially for the dust particle counter, be more careful so as not to damage the internal components.
10、Particle counter is mainly used to test the clean environment of clean room, when the place of measurement has loose particles of material, dust source, spray place, must keep at least twelve inches away from the inlet tube. In order to avoid the above particles and liquid pollution sensor and pipeline.
