Ashtead Technology, provider of custom engineered solutions, explains how the MCERTS scheme for environmental monitoring equipment provides several important advantages beyond regulatory compliance.

Emissions to air from combustion processes are tightly regulated. MCERTS is the Environment Agency’s Monitoring Certification Scheme. Administered by Sira Certification Service, it provides certification for equipment, personnel and inspection services, and underpins the quality and reliability of monitoring data.

One of the most popular instruments from the Ashtead Technology fleet is the MCERTS approved Testo 350 emissions and combustion analyser. 

The Testo 350 is a portable analyser designed for service measurement, tuning and compliance testing on industrial engines, burners, boilers and gas turbines. The instrument is able to measure up to 6 parameters with sensors available for oxygen (O2), sulfur dioxide (SO2), CO, caebon dioxide (CO2), nitrogen dioxide (NO2), nitric oxide (NO), Hydrocarbons (CxHy), COlow, NOlow, and hydrogen sulfide (H2S).

Reasons for using MCERTS equipment

– Emissions monitoring data play a significant role in the choice of abatement equipment, so accuracy helps to ensure that technologies (and costs) are appropriate

–To optimise process control. The components of emissions in combustion processes, for example, provide an indication of the efficiency of combustion and help process managers to ensure a clean burn.

– The use of MCERTS equipment also sends a strong message to stakeholders that the organisation is committed to accurate environmental measurements; one of the key elements in an environmental management policy.

– Occasionally environmental measurements are challenged; either in court or in the media by lobby groups. In such circumstances, it is vitally important to be able to deliver scientifically defensible data from certified instruments.

– MCERTS approved monitors are also employed by organisations to protect the health and safety of staff, visitors and local residents. So again, it is important that an organisation trusts the data that it generates, and that this data is scientifically defensible.

Monitoring particulates

The government has estimated that 29,000 premature deaths occur in the UK every year as a result of particulate pollution. Dust monitoring is therefore another application with a high demand for MCERTS instruments in the search for ways to reduce exposure. 

Researchers and consultants are looking to identify pollution hotspots and the factors affecting them, and Government and local authorities are looking for successful mitigation measures and infrastructure investments with beneficial effects on air quality. At the same time, planning authorities are imposing monitoring conditions on proposed developments, and with so much at stake it is vital that measurements are accurate and reliable.

The TSI DustTrak Environmental is ideal for these applications. As an MCERTS approved ambient air quality monitor, it is certified for monitoring PM2.5, PM10 and total PM. Furthermore, it can be mains or battery powered, and is web-enabled, which means that it can be quickly and easily deployed in almost any location; from a building site to a busy urban street. This remote connectivity means that users have access to live data, and receive alarms automatically by text or email. 

In many respects, environmental monitoring is about risk reduction; protecting the environment, occupational safety and brand reputation.
