The air monitoring dust meter PFM-AD12 at the Matsushima factory in Japan has the following features:：

• The measurement method is unique.Using the triboelectric charging method, it can detect dust particles with a size greater than or equal to 0.3μm, and the humidity requirement for the dust is less than or equal to 40 vol%.

• Adjustable sensitivityThe detected concentration range is 0.1 to 1000 mg/m³, with 9 sensitivity levels available for switching, from Sensitivity 1 (low sensitivity) to Sensitivity 9 (high sensitivity), which can be adjusted according to actual needs.

• The output signals are diverse.It has a DC4~20mA output signal, with a current of 23.3mA. It is also equipped with a fault alarm and an upper limit alarm, both 1c×1, to meet the signal transmission and alarm requirements in different scenarios.

• Clear and intuitive display.It uses a 4-digit display with a concentration range of 0.0 to 118.5%, allowing users to intuitively understand the dust concentration situation.

• Variable integration timeThe integration time can be variably set within the range of 0 to 30 seconds, enhancing operational flexibility.

• Protect the structural reliability.The protective structure meets the IP54 standard, ensuring that under normal working conditions, the enclosure, wiring at the lead-in ports, and the locked state effectively prevent the ingress of dust and water.

• Moderate weight for easy installation.The total weight of the machine is approximately 6.6 kg, which will not impose excessive burden during installation and use.

• Wide range of applicationsIt can be applied in various places such as landfills, offices, hotels, and factories for continuous monitoring of smoke and dust, capable of measuring concentrations of PM2.5 and other particles, thereby contributing to the labor environment and safety.
