Monitoring & metering I
nternational equipment rental and solutions specialist Ashtead Technology has launched two new indoor air quality monitors that will help building and facility managers to protect people from toxic gases, as well as airborne particles and viral aerosols. The TSI 8144-4 measures formaldehyde, carbon
monoxide, total volatile organic compounds, carbon dioxide, temperature/relative humidity, particulate matter and barometric pressure. This instrument therefore provides an ideal solution for monitoring the most common indoor pollutants to help achieve optimal indoor air quality. The TSI 8144-6 monitors the same parameters,
but instead of formaldehyde it measures ozone, nitrogen dioxide and sulfur dioxide. This means that the TSI 8144-6 is ideally suited to buildings in urban or industrial locations where air drawn from outdoors may be polluted. Josh Thomas, Ashtead Technology’s senior sales manager, says: “Currently, the greatest demand is coming from organisations that need to monitor carbon
dioxide (CO2) in the workplace as this has been linked to higher COVID-19 infection rates. “Whilst it is important for particulates and potentially
dangerous gases to be continually monitored, for many workplaces the most serious risk is airborne coronavirus aerosols being exhaled by asymptomatic individuals. These particles are usually less than five micrometres in diameter, and therefore similar in size to
cigarette smoke, which as we know does not settle and tends to linger in poorly ventilated spaces. “The TSI monitors can help detect situations in which people have spent too long in a confined space, exhaling carbon dioxide, and potentially coronavirus aerosols. Occupied spaces with good ventilation may contain
350-1,000 ppm CO2, but anything above this can induce drowsiness, with levels above 2,000 ppm causing headaches, increased heart rate and slight nausea. “We recently worked with a national newspaper to
investigate CO2 levels in London stores; worryingly, two of them showed CO2 levels above 1,300 ppm, indicating inadequate ventilation to reduce COVID-19 risk.”
The monitors are supplied with TSI Link Solutions cloud-based software which provides customised alerts and 24/7 remote access to the monitors for measuring air quality data in real-time. Thomas adds: “We are offering the TSI 8144-4
monitor for sale at just £815, and the TSI 8144-6 for £1,210, which means that almost anyone with responsibility for health and safety can afford to monitor all of the most important indoor air quality risks with an instrument that can be installed in under ten minutes.”

Indoor air quality monitors
Remote dust and noIse monItoRIng R
esponding to a flurry of recent customer requests, Ashtead Technology has developed a remote monitoring solution for the continuous measurement of both noise and dust.
“These are two of the most important pollutants – especially at construction and demolition sites,” explains senior sales manager Josh Thomas. “So it made sense to develop a single system that could accurately monitor both parameters simultaneously and deliver continuous data remotely. Our engineering team therefore developed a solution that combines the key advantages of two separate TSI technologies, and I am delighted to confirm that it is now available to all of our customers for rental or purchase.” Dust and noise monitoring are required at sites where they present a potential hazard to site workers and the local community. Consequently, these monitors will be employed for health and safety purposes, in environmental investigations and in compliance with planning requirements stipulated in a site’s permit. The TSI DustTrak & SoundPro remote dust and noise monitoring
system is supplied in a weather-proof, lockable enclosure, complete with the EnviroNet software platform which enables users to access the data with any web-enabled device. This wireless, cloud-based management system provides secure access to data at any time from anywhere, and enables the configuration of text and email alerts when noise or dust
64
levels meet user-set conditions. The TSI DustTrak complies with the
MCERTS performance standards for measuring PM2.5, PM10 and total PM across a broad range of 0 - 150mg/m3
.
The TSI Quest SoundPro offers class/type 2 noise monitoring with 1/3 Octave Band analysis. The unit can be powered via mains, solar panels or leisure battery, making it suitable for indoor and outdoor monitoring requirements. Summarising, Thomas says: “This is a
great example of Ashtead Technology responding to customer needs; utilising its experience and expertise to deliver a solution that will be ideal for a wide variety of applications. “With this technology, our customers will be able to quickly and
easily deploy the latest monitoring technology in almost any location, with immediate access to continuous data, which will reduce the requirement for site visits and save costs. However, the greatest benefit will be the confidence and assurance that the site is in compliance with noise and dust regulations.”
