What Is a Dust Monitor?
A dust monitor (analyzer) is a device used to measure particles in gases. Also called dust meters, they are used to measure particles in working environments and for building management.
In addition to dust meters, particle counters are other devices that can measure particles in gases. These products are designed for use in spaces that are cleaner than dust measuring instruments, such as clean rooms in pharmaceutical and medical device manufacturing plants and isolators for quality testing.
Uses of Dust Monitors
Unlike particle counters, which are designed for use in clean spaces, dust monitors are used in places with a certain amount of suspended particles. They are suitable for measurement in general rooms or outdoors where cleanliness is not controlled, or in spaces with even higher particle concentrations, such as factories.
Dust monitors are used to measure PM2.5 because they can perform measurements in the air. It is not uncommon for measurement of mists, including oil mists, to be difficult due to issues such as contamination of the inside of equipment by oil and varying susceptibility to different types of oil mists.
Principle of Dust Monitors
There are several types of measurement methods for dust monitors, including light scattering and piezobalance (piezoelectric balance) methods as representative examples. Of these, the light scattering method is the most widely used in dust measuring instruments.
When light is incident on particles in a gas, light scattering occurs. Since the amount of scattered light is known to be proportional to the dust concentration, the dust concentration can be estimated by measuring the amount of scattered light. This is the measurement principle of the light scattering method.
One point to note about the light scattering method is that it is based on the precondition that the particle properties are uniform. If this condition is met, the reproducibility of the measurement results is good, but if particles of various properties are mixed together, the validity of the measurement results must be checked each time.
The piezobalance method, on the other hand, measures the mass of particles collected on a balance to determine the dust concentration in the aspirated air. Because this method measures the mass of particles, it has the advantage of not being affected by the properties of the particles, unlike the light scattering method. The disadvantage is that periodic cleaning is mandatory due to the limited amount of particles that can be collected.
