Powder Measuring Instrument

Monitor dust concentration of facilities operating indoors and outdoors

Air Dust Monitor is a dust indicator that specializes in monitoring dust generated from machinery operating indoors and outdoors in factories and construction sites.

It can be used to predict the start of dust leakage, prevent dust generation indoors and outdoors, and check the effectiveness of dust collection measures.


It can be used for health management and quality maintenance through constant monitoring. The dust generated in the factory can harm the health of workers and adhere to the produced products, resulting in deterioration of quality. If you constantly monitor dust, you can take early countermeasures and easily maintain and manage a clean work environment.

Features of Air Dust Monitor

Our Air Dust Monitor adopts triboelectric (charge) method. Its main features are:

24-hour monitoring
on behalf of humans,
not overlooking the
slightest dust

Dust concentrations of 0.1 to 1,000 mg/m3 are constantly measured, so even the slightest amount of dust is not overlooked.
It can be used to quickly detect dust generated from equipment, helping to manage the health of workers and quality control of products.

Handy and can be carried to the site of concern

It is lightweight and comes with a handle, so you can freely carry it wherever you want. Measurement can be performed at multiple locations anytime, anywhere as needed without permanent installation.

Can be installed without a battery and wireless communication power supply

Dust can be measured reliably even in high places, narrow places, and places where power supply is not available. Since it is equipped with a battery and wireless communication device, wiring work is unnecessary. It also contributes to the reduction of construction costs.

Operating principle

Air Dust Monitor is dust monitor with a self-suction function that enables dust measurement in environments with no air flow.

Dust taken in from the space by self-suction generates electric charge transfer (tribo) when it contacts or passes near the internal probe. The amount of charge transfer is detected as a relative concentration proportional to the dust concentration.

How to use?

1. Select

Check environment where dust is a concern. Select the separate type for high or narrow locations, or the battery/wireless type if remote wiring is not possible.

2. Installation

Place the unit horizontally on floor or hang it on wall. Direct suction hood toward dust-generating area as much as possible.

3. Wiring

Wire power supply, analog output, and contact output to the converter. Separate type and battery/wireless type connect the sensor and converter with a dedicated cable.

4. Adjustment

Orient suction hood in a direction that facilitates dust collection. Select range from 1 to 9 settings, and set integration time if necessary.

*For details, please refer to the instruction manual.


If you use it for a long time, you may be concerned about the soundness of the Air Dust Monitor.

We offer maintenance-friendly designs and long-term reliability services.

To remove sensor,
simply remove fastener

When removing sensor for maintenance, probe can be easily pulled out by removing the two fasteners (red arrows) 


Please work after turning off the power of the main unit.

To clean, just wipe
probe with a waste cloth

For cleaning, simply wipe off dirt from the probe with a slightly damp cloth. If there is little dust leakage, it is not dirty, so it is recommended to clean it when the equipment is stopped.


If you clean the probe as it is, it will short circuit the board, so turn off the power, wear insulated gloves, and work with the ground connected.

After-sales service is
available for those
who are concerned
about soundness

If you are unsure if your equipment is working properly, please use our calibration and adjustment service.


Our service personnel will come to the site and respond. Also, if you send the main body of the device to our factory, we can check it.
