Designed for continuous outdoor deployment across real-world environments.

Is Persium right for us?

We already have an air quality monitoring system. Why would we need Persium?

Fixed monitoring stations give accurate readings at a handful of points, but they leave blind spots in between and are slow and costly to expand. Persium Pods add hyperlocal coverage at the places that matter (a construction site, a port boundary, a plant fence line), capture gas and particulate channels your current setup may not resolve so you can trace problems to their source, and can be deployed quickly without a long procurement cycle. Our dashboard and digital twin software then turn the readings into alerts, trends and reports, backed by calibration against reference stations and a database of 5,500+ stations for benchmarking, with regional distributors handling on-the-ground maintenance.

We're a small local authority with a limited budget. Is this realistic for us?

A network of Pods can be placed where they answer a specific question, such as a known hotspot, a school, a complaint area or a major roadworks site, at a fraction of the cost and lead time of a reference-grade AQMS station. Starting with a short pilot lets you prove the value of real data before committing further, and we will handle on-the-ground maintenance, so you do not need to add staff or technical expertise. We would also be upfront if your needs are already met by what you have, so the best first step is a conversation about the specific problems you are trying to solve and a budget range, and we can tell you honestly whether Persium is an appropriate fit or not.

How does Persium compare to low-cost consumer sensors?

Consumer sensors are designed for personal curiosity, not operational decisions. They typically measure one or two parameters, have no calibration programme, and provide no certified data trail. Persium's Pod measures 31 parameters and its Pill measures 21, both with continuous quality assurance. If your data will be used to justify investment, inform policy, or meet a regulatory standard, it needs to be at a much higher standard than low-cost consumer sensors bought online.

Do you work outside the UK?

Yes. We work internationally, with clients across the EU and the GCC and a presence in Africa and Asia. We are headquartered in both London, UK and Abu Dhabi, UAE. Sensor calibration is adapted for local atmospheric conditions, and our platform supports the regulatory frameworks relevant to each region.

What kinds of organisations work with Persium?

Ministries of environment, local authorities, smart cities, mining & quarrying, oil & gas, transport operators, metros, petro-chemical, waste management, airports, port authorities, district cooling, wastewater treatment & sewage infrastructure, real estate developers, construction sites, and environmental consultancies. The common thread is a need to make infrastructure or policy decisions that depend on accurate, real-time environmental data, not estimates.



Procurement & commercial

How do I get a quote?

Please contact us directly and we will scope a deployment based on your geography, number of monitoring points, required parameters, and how you intend to use the data. Pricing depends on configuration bespoke to your monitoring requirement.

Can we run a small deployment before committing to something larger?

Yes. We regularly work with new partners who want to validate the approach in a defined area before scaling. This lets you see real data from your environment and understand what the platform can do before making a broader commitment.

What's included in a deployment? Is it hardware only, or software too?

Both. Persium provides the sensors, the cloud platform, the data visualisation dashboard, API, and ongoing technical support. You are not buying hardware and then sourcing software separately. Everything is designed to work together.

What does ongoing support look like?

Persium handles sensor maintenance, calibration, firmware updates, and platform support as part of the service. You are not managing hardware, you are utilising what the data provides to you.



Data, compliance & reporting

Can Persium data be used in regulatory submissions or official reports?

Persium data has been used to inform policy discussions, planning applications, and regulatory monitoring programmes. Whether it meets the specific evidential standard for a particular submission depends on the regulatory body and the use case.

How does the device communicate?

LTE/4G; CAT/M1; NB-IoT; GSM; LoRa; Wifi; MQTT; CBRS; MODBUS; Ethernet. Whatever the requirement, we adapt to the available network infrastructure at each site.

Does the platform integrate with our existing systems?

Yes. The Persium platform is built with open APIs, so data can feed into your existing dashboards, GIS tools, or reporting systems. We are experienced in integrating with third-party platforms and can advise on the specifics of your setup.

Can we share air quality data publicly?

Yes, if you choose to. Several Persium partners use the data to power public-facing dashboards or transparency reporting. This is entirely your decision, the platform supports both private and public data sharing configurations.

How does Persium handle data quality and calibration?

Sensors are calibrated before deployment and monitored continuously. Persium uses a combination of reference-grade colocation and automated quality assurance algorithms to flag anomalies.

Does Persium help with ESG or sustainability reporting?

Yes. Organisations using Persium have incorporated air quality data into ESG frameworks and sustainability disclosures. We can help you understand how the data maps to specific reporting standards relevant to your sector.



Specific environments

Can Persium operate in extreme heat or desert conditions?

Yes. Persium Pods have been designed specifically for extreme heat (≈85°C), dust and humidity. We have installations across the GCC and in Africa, which are high temperature environments.

We're pursuing LEED or WELL certification. Can Persium data support that?

Persium monitors many of the indoor environmental quality parameters relevant to LEED and WELL, including particulate matter, CO₂, VOCs, temperature, and humidity. We can advise on how our data maps to specific certification requirements, though formal certification decisions rest with the relevant accreditation body.

Can Persium monitor both indoor and outdoor air quality in the same deployment?

Yes. The platform is designed to capture both simultaneously, which is particularly useful for buildings or transport assets where understanding the relationship between outdoor pollution and indoor air quality is important. Airports, transport systems, metros, and mixed-use developments are common examples.

We operate port or logistics sites with complex pollution sources. Can Persium handle that?

Yes. Ports and logistics environments involve a mix of vehicle exhaust, cargo handling, and shipping emissions that create layered pollution patterns. Persium's sensor density and mobility, including vehicle-mounted deployments, make it well-suited to mapping those sources accurately.

Does Persium measure WBGT and heat stress indicators?

Yes. The Persium Pod measures temperature, humidity, wind, and other related parameters that feed into heat stress and WBGT calculations.
