Particles Counters

A particle counter is a device that is used to detect and count physical particles. They count the amount of particulate contamination from the air, a surface or a liquid. Some examples of these particles can be anything from metal, oil, dust, shavings, ash, smoke, mold, or other biological contaminants. This instrument is very useful to professionals for determining how pure the air is for breathing, water treatment, producing food and drugs or microchips in a clean room.
GAOTek developed advanced particle counters that are high quality, affordable, and accurate. They are very versatile instruments for detecting physical particles. We have a wide variety of selection of particle counters that will help you determine contamination from air or in a liquid, with the simplest operation. With precise measurements, we ensure that you will be satisfied when using our products.

GAOTek particle counters are the best when it comes to quality and high accuracy readings. The process can be done in an effective and efficient way with GAOTek’s various functionality of particle counters.

Technologies

There are three primary categories of particle counters: Aerosol particle counters, liquid particle counters, and solid particle counters.

·         Aerosol particle counters – Are used to determine the air quality by counting and sizing the number of particles in the air. It is useful in understanding the cleanliness level in a controlled environment. It is also useful in determining the amount of particles inside a building or in the ambient air.

·         Liquid particle counters – These particle counters are also used to determine the cleanliness level of hydraulic fluids. The reason is that 75-80% of hydraulic breakdowns can be contributed to the contamination.

·         Solid particle counters – These ones are used to measure dry particles for various industrial applications. One example is for the detection of particle size from a rock crusher within a mining query.

A particle counter is composed of different parts that are used to detect physical particles and help users to navigate easier on the device. The list below are the systems of a particle counter.

·         Optical System – Typically in the device, a laser is used as the light source, and in many commercial instruments, it is a He-Ne laser. Particles that pass through the laser beam scatter light that is collected by the optics and is then directed to the photodiode. A parabolic mirror with a very high reflectivity collects the optic.

·         Air Flow System – Used to isolate the particles from the optical components and more importantly confine the particle stream to the boundaries of the laser beam. 

·         Electronic System - The photodetector electric signal is preamplified and pulse height measurement electronics classifies the signal into a size bin. The particle counter increments by one on each pulse recorded in the appropriate size bin. The display system increments the display in each channel on a real-time basis as the sample aerosol flow continues to enter the measuring chamber.

Features

GAOTek thermal imagers offer a lot of key features that are helpful in operating the device easily and for an accurate reading.

·         The on-off control is a toggle function. Pressing the on/off key will turn the device on or off. If the hygrometer is left on with no activity for a period of time, the unit will turn itself off to conserve the battery.

 

·         Portable in size with easily accessible buttons to access interface quickly

 

·         Six particle-size channels (0.3, 0.5, 1.0, 3.0, 5.0, 10μm)

 

·         Date and time display

 

·         Data Easily Downloaded to a Computer

 

·         Compact and Easy to Handle

 

·         A low battery indicator is also included. A weak battery can cause imprecise measurements or improper operation. A low battery indicator is provided on the display to show that the battery needs to be recharged. It is required to charge the battery to make sure that you get the best results in the device

·         Internal Audible Alarm

 

·         Multiple print-modes

 

·         A variable response time and a large memory to store the data

 

·         A built-in printer

 

·         Integrated particle collection filter for offline analysis of optically analyzed particles

In addition to all these features, our products have a high precision of measurements, a high resolution and quick sampling speed. More importantly, our products are also affordable when it comes to your budget. You can have different options to choose from with all the various kinds of thermal imagers manufactured by our company.

Applications

Particle counters are commonly used in research application listed below:

·         Basic Aerosol Research

·         Health Effects Studies

·         Particle Formation and Growth Studies

·         Atmospheric and Climate Research

·         Environmental Monitoring Studies

·         Nanotechnology Research

·         Combustion and Engine Research

·         Inhalation Toxicology Research

·         Mobile Aerosol Studies

These facilities are some examples of where particle counters can be used for. It helps to maintain the cleanliness of the area. It detects the particle that can cause contamination and prevent people from getting health problems, especially in biological laboratories.
