Dust Sentry TSP Monitor
The Dust Sentry TSP Monitor provides continuous real-time monitoring of total suspended particulate (TSP), producing accurate, defensible data, accessible anywhere. Suitable for use on a range of projects, including construction, remediation, brownfield developments, fenceline monitoring, and waste management.
Continuous real-time measurement of total suspended particulate (TSP) – accessible via any wireless device
Robust, weather-proof enclosure, suitable for use in most conditions
Can be configured to measure PM10, PM2.5, or PM1
Product Overview
The Dust Sentry is a modular air quality monitoring instrument for the measurement and compliance of specific dust and particulate designation. The Dust Sentry TSP Monitor uses a well proven near forward light scattering nephelometer and high precision sharp cut cyclone to provide continuous real-time data on total suspended particulate matter (TSP).
Packaged in a robust weather-proof, lockable enclosure, the Dust Sentry is light enough for one-person site installations. The instrument includes an embedded PC, up to 20 years of on-board data storage, and a powerful air quality monitoring software. With Aeroqual Cloud you can remotely access data via a web browser on any device, even when your instrument is offline.
What can it measure?
The Dust Sentry TSP Monitor provides real-time measurement of total suspended particulate matter (TSP), with a measurement range of 0-60,000 μg/m3. By changing the sharp cut cyclone, the Dust Sentry TSP can be configured to measure PM10, PM2.5 or PM1. For simultaneous measurements please see the Dust Sentry.
Options to integrate environmental sensors, such as wind, noise, weather, and solar radiation make this a complete air monitoring solution for your project.

Common Questions
Before you talk to us have a look at some common questions that customers ask.
No. However, some of our distributors offer rental packages. If you’d like us to put you in touch with a local distributor who offers rental equipment, please contact us.
No. The Dust Sentry only measures dust and particulate matter.
For BTEX see our Real-Time BTEX / Benzene Monitor.
No. However, the AQS Air Quality Station is configured to measure gases and particulate matter at the same time.
No. However, the enclosure is a lockable IP65 glass-reinforced plastic (GRP) cabinet with integrated aluminium solar shield armour.
What is the environmental operating range for the Dust Sentry?
The Dust Sentry is designed to operate in environments from -10°C to +50°C (14 °F to 122 °F)
Is the data gathered in real time?
Yes, measurements are logged and reported in real time.
What maintenance does the Dust Sentry require?
The Dust Sentry requires relatively low service and maintenance. Average service checks and filter replacements are recommended every three months. Factory calibration of the optical module is recommended annually. The optical module is easily removed and can be shipped to Aeroqual by small parcel courier service. The turnaround is approximately four weeks. For large networks which are required to operate 24/7 all year round we suggest maintaining one or more spare optical modules for exchange in instruments as service is required. Pumps are long-life high quality BLDC diaphragm type by KNF with lifetime 1-3 years. Pumps are easily replaced by the end user.
Here's what we recommend for maintenance of your Dust Sentry. View full details in the Dust Sentry User Guide.
Does the Dust Sentry have a datalogger?
Yes. It has 32GB Hard Drive (>5 years data storage).
What is the file type when you send out your data from the equipment?
File types can be CSV or FTP.
See the Aeroqual Cloud Infographic to see further details of how it works.
Is it compliant with U.S. EPA standard?
Aeroqual Dust Monitors are not U.S. EPA approved instruments but it is a near reference particle monitor for specific dust fractions.
Can the Dust Sentry be connected in the ethernet, so we can remotely access it?
Yes. You have three options to connect to the device:
Standard: WIFI
Ethernet (LAN)
Optional: Cellular IP HSPA 4G modem.
Can you integrate a third-party weather station in the Dust Sentry?
Yes, a power and data interface for designated third party sensors is included.
Here is a list of the environmental sensors that integrate with the Dust Sentry system:
Gill WindSonic (ultrasonic wind sensor)
Vaisala WXT536 (weather transmitter)
Airmar 200WX (weather station)
Cirrus MK427 Class 1 (noise sensor)
Novalynx Pyranometer (solar radiation)
For more details click on the Accessories tab on the Dust Sentry product page.
How do I install the Dust Sentry? What do I need to have for installation?
The instrument is packaged in a robust, lockable enclosure and is light enough for one-person site installations.
See the Dust Sentry User Guide on for full details on how to install the unit.
Is the sensor calibrated when we receive it? How do I calibrate the sensor?
Yes, it is already factory calibrated. All Aeroqual PM engines need to be returned to the Met One Instruments factory in the U.S for service and calibration at the following recommended intervals:
Dust Sentry Particle Monitor: 24 Months
Aeroqual can arrange for this service. Contact support@aeroqual.com for further details.
Can it run through solar or battery?
Yes. To read more, see this technical note on How to remote/solar power the Dust Monitor.
Does it have self-diagnostic and self-correct function?
No. However, it has alerts to notify you that there is an error that needs attention. Those alerts can be set by the end user.
Does the Dust Sentry have a weatherproof enclosure?
Yes, the enclosure is a lockable IP65 glass-reinforced plastic (GRP) cabinet with integrated aluminium solar shield armour.
What is the dimension and weight of a Dust Sentry?
483 H x 330 W x 187 D mm (19 H x 13 W x 7.4 D inches) includes solar shield armour and mounting brackets and it weighs <13 kg (28.6 lbs).
Does the Dust Sentry have any certifications?
Yes. Dust Sentry PM10 and Dust Sentry PMX are MCERTS certified by UK Environment Agency and Pre-approved for Rule 1466 compliance by SCAQMD, USA.
