A. Product Overview

Temtop PMS16 is an external pump laser particle sensor designed to provide solutions for online monitoring of atmospheric environments. It is widely used in micro air monitoring stations, dust monitoring systems, oil-smoke monitoring, and other air monitoring systems.

The sensor uses an all-metal optical-mechanical structure and allows users to install an external pump with a flow of 1.1 L/min, which can also be customized. It is compact in size and suitable for integration into multiple devices, with a laser life exceeding 20,000 hours.

B. Working Principle

The PMS16 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. The photoelectric collection unit converts the scattered light into voltage pulse signals, which are then converted into digital signals after pre-amplification and analog-to-digital conversion.

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

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

C. Why It Is Used

The PMS16 is used for monitoring particulate matter concentration in atmospheric environments where online and continuous measurement is required.

It is applied in:

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

The use of an external pump allows flexible airflow control depending on application requirements.

D. Suitable Buyers

Based on the applications and design mentioned in the document, PMS16 is suitable for:

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

E. FAQ (SEO-Optimized, PDF-Based)

1. What parameters does PMS16 measure?
