A. Product Overview

The Temtop PMS10 is a pump-suction laser particle (dust) monitor designed to provide solutions for online monitoring of atmospheric environments. It is used in applications such as micro air monitoring stations, dust monitoring systems, oil-smoke monitoring, and other air quality monitoring systems.

The device uses a precise optical-mechanical structure and is equipped with a four-wire brushless vacuum pump for efficient air sampling. It is compact in size, suitable for integration into multiple devices, and supports continuous operation for up to 10,000 hours under normal conditions.

B. Working Principle

The PMS10 operates based on the MIE scattering principle to monitor particle concentration.

When air passes through the light collection chamber, particles scatter light from the beam. A photoelectric collection unit converts this scattered light into voltage pulse signals. These signals are then converted into digital signals through pre-amplification and analog-to-digital conversion.

• The number of voltage pulses corresponds to the number of particles
• The amplitude of the pulses represents the particle size

After calibration using standard substances, the system determines the particle concentration in the environment.

MIE scattering occurs when particle diameter is comparable to the wavelength of radiation, with stronger forward scattering and directional characteristics.

C. Why It Is Used

The PMS10 is used for monitoring particle concentration in atmospheric environments where continuous and accurate measurement is required.

It is applied in systems such as the following:

• Micro air monitoring stations
• Dust monitoring systems
• Oil-smoke monitoring systems
• General air monitoring systems

The use of pump-suction sampling improves sampling efficiency and ensures consistent airflow for measurement.

D. Suitable Buyers

Based on its described applications and integration design, the PMS10 is suitable for:

• System integrators developing air monitoring systems
• Manufacturers of environmental monitoring equipment
• Developers of micro air monitoring stations
• Industrial users requiring dust and oil-smoke monitoring systems
