UK FOCUS xi New indoor air quality monitors
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 the 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 sulphur 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, said: “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 5 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
national newspaper to investigate 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 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. For More Info, email:

Compact High Performance Gas Sampling Diaphragm Pump
NEW
High-Performing: N 96 Diaphragm Vacuum Pump and Compressor for Gas Sampling and Instrumental Analysis
‘Thinking out of the box’ is usually a phrase that R&D engineers use as a metaphor for looking at a challenge from a different perspective but Signal Group’s technology development team have taken the phrase to a new level. Following an intensive development program, the company has announced that all of their main line S4 gas analysers are now available with a detachable tablet instead of the traditional built-in screen.
“We are not aware of any off-the-shelf gas analysers with this capability anywhere else in the world, so this will dramatically disrupt the gas analyser market,” comments Signal Group’s Stephane Canadas. “No longer will customers have to manage their analysers, while standing, sitting or squeezing into inconvenient or even hazardous locations; now they will be able to operate their equipment wirelessly from a convenient location nearby, using the instrument’s built-in Wi-Fi.
“The even better news for our international customers, is that we can now confirm that the tablet is available with user-selectable multiple languages.”
The new tablets are rugged with an IP65 rating, which means that they can even be used outdoors. However, the applications where the detachable tablet will be of greatest value include: analysers in an ATEX enclosure; vehicle exhaust gas test cells; on a raised stack gantry; in a combustion test rig, or on any site where the location of analysis is not an ideal or safe working space.
The new S4 Tablet connects wirelessly to the analyser via an inbuilt 802.11 Wi-Fi which can connect up to 50 metres away, and the tablet’s enhanced Graphical User Interface (GUI) uses intuitive graphical icons for all the main functions. This provides users with the ability to view live data remotely, and even manage data logging, alarms and calibration.
In addition to wireless connectivity between the analyser and the tablet, all Series 4 instruments are supplied with software which provides users with simple and secure access via RS232 or Ethernet at any time, from anywhere.
From April 2021, the new S4 Wireless Tablet will be supplied as standard on all new orders for the Series 4 gas analysers, which includes the Solar, Quasar, Pulsar and Aurora models.

KNF showcases a new powerful pump for a wide range of applications. The N96 is suited for gas sampling analysis and all other processes requiring reliable and precise transfer of gaseous samples. Compact and high performing, it can transfer even aggressive & corrosive media. Its robust design means it can be used with a broad spectrum of media at temperatures up to 70 degrees Celsius.
Available with either an EPDM membrane or a PTFE coated membrane, the N96 is chemically resistant and highly tolerant of vapour and condensate, making the N96 perfect for use in instrumental analysis. In this field, the N96 can perform the typical tasks of gentle, precise preparation and transfer of samples for analysis as well as safe aspiration of chemical liquid waste mixtures.
With its highly efficient brushless DC motor and rotational speed control, this diaphragm pump can dynamically meet the requirements of complex operating profiles. The N96 low heat emission makes it suitable for use in ambient temperatures of up to 50 degrees Celsius. The pump can effortlessly start up against load, has a flow rate up to 8.5 l/min and can produce 2.5 barg pressure and vacuum down to 100 mbar abs, whilst running continuously.
