The dust particle counter is an instrument used to measure the number and size of particles in the air, so as to provide a basis for the evaluation of air cleanliness, and can also be used to monitor the filtering effect of the filter
.
Although most dust particle counter manufacturers use the same principles, the design details of each are different
.
For example, the flow rate, sensitivity, size range and number of counting channels of the dust particle counter, the durability of the laser or laser diode, the lifetime of the light source, and the ability to maintain calibration are all important factors to consider
.
Typically, the dust particle counter used in the cleanroom is selected based on the specifications and cost of the instrument
.
Details determine success or failure.
The dust particle counter is not difficult to operate, but there are many precautions.
A little negligence will affect the detection results, and may cause an explosion
.
The laser dust particle counter (50L/min) is used to measure the size and number of dust particles in a unit volume of air in a clean environment
.
The laser dust particle counter adopts a semiconductor laser light source and a large touch screen display, which provides a simple operation mode, fast sampling, light weight and easy portability, which effectively saves the operator's time
.
The lightweight, streamlined stainless steel housing and ergonomic handle allow users to easily lift it with one hand and place it anywhere suitable for measurement
.
In addition, the stored data can be downloaded via computer software
.
Products are widely used in clean environment testing departments of medicine, optics, chemistry, food, cosmetics, electronic hygiene, biological products, aerospace and other industries
.
Product features: 1.
Using the original Japanese laser diode, with longer life and more stable performance; 2.
Using 7-inch touch screen control, the human-computer interaction interface is beautiful, simple and easy to operate; 3.
User function management at all levels, management is more orderly, Effective; 4.
Large flow can save sampling time
.
Product performance: 1.
50L/min (1.
77cfm) sampling volume; 2.
AC and DC dual-use; 3.
Touch screen control operation; 4.
Six-channel particle size display on the same screen, showing particle concentration (particles/m3); 5.
Automatic UCL calculations
.
So, what are the precautions for it? What is the correct way to use it? Small details, big problems 1.
Do not start the counter when the inlet tube is capped or blocked
.
2.
Do not measure mixed gases (such as hydrogen and oxygen) that may react, because these gases may explode in the counter
.
3.
Do not sample compressed air without a high pressure decompression device (such as a high pressure diffuser), all particle counters are designed to operate at one atmosphere
.
4.
Water, solutions or other liquids cannot enter the sensor from the inlet tube
.
5.
The dust particle counter is mainly used to test the clean environment of the purification workshop.
When there is loose particle material, dust source, and spray point in the measurement place, it must be kept at least twelve inches away from the inlet pipe to prevent the above particles and liquid from contaminating the sensor.
and piping
.
6.
When sampling, the gas discharged from the counter itself or polluted by the gas discharged from the counter should be avoided
.
7.
When connecting an external printer, turn off the counter first; when performing printing operations, there must be printing paper on the printer, otherwise the print head will be damaged
.
8.
Particle counters with a sensitivity of 0.
1 microns, without special precautions, cannot be used in purification workshops larger than 1000 to avoid damage to their sensors
.
How to use it 1.
Read the safety instructions This is a step that is easily overlooked.
Many customers will feel that there is no need to read the "safety instructions" carefully, as long as they can use it
.
This idea is so wrong! ! ! Read the user manual in its entirety to obtain more detailed information to prevent inaccurate test results or adverse effects on the instrument itself due to improper operation
.
2.
Remove the cover (black cap) of the isokinetic motion probe.
Before use, remove the cover (black cap) of the isotropic motion probe, otherwise the particle counter will be damaged
.
If used in areas where particle counter access is difficult, follow these steps: a.
Loosen the threaded isokinetic probe
.
b.
Replace the removed probe with the suction nozzle
.
c.
Connect the high-purity tube to the suction nozzle
.
d.
Connect the barbed isokinetic probe to the open end of the tube and set the particle counting mode
.
3.
Parameter selection The parameters in the particle counter main screen can be selected through the setup screen, clock setup menu and label setup menu
.
In the test interface, if you need to change the working parameters, press the "Exit" key to return to the parameter setting state
.
4.
Self-cleaning The instrument should be self-cleaning before sampling to ensure that there are no residual particles inside the instrument
.
Be sure to use an isokinetic energy sampling head when sampling, and pay attention that the sampling tube is not blocked or bent, and the sampling tube should not be too long
.
The instrument is prohibited from extracting gas with high concentration of particles (such as dirty air) and containing water vapor, oil and gas, and corrosive gas into the instrument, otherwise it will pollute the gas path and optical path components of the instrument, and even cause damage
.
