10 Sensor Technology Best-in-class particulate matter (PM) sensor added to world-class sensor portfolio
Ion Science Ltd has recently formally announced the addition of a high-specifi cation Particulate Matter (PM) sensor to its portfolio. ION Science now arguably offer both the world’s best-performing Photoionisation Detection (PID) and Particulate Matter (PM) sensors, further supporting the company’s status as a global leader in sensor supply and service.
NextPM is the latest innovation from TERA Sensor, a company by Groupe TERA, designed for use in industrial, environmental monitoring, and smart city applications, it is widely perceived as the most advanced particle measurement solution available on the market. The sensor features advanced technical innovations that enable ultra-precise measurements to be obtained, even in extreme climatic conditions. Providing real-time PM1, PM2.5 and PM10 measurements in both μg/m3
and pcs/L, compared with some alternatives on the market which are only able to estimate PM2.5 and PM10. NextPM has
been independently verifi ed by South Coast AQMD as the world’s best-performing, low-cost particulate sensor, ensuring high performance across a wide range of applications and environments.
ION is now a global distributor for TERA Sensor with exclusive distribution rights throughout the UK. Duncan Johns, Managing Director of ION Science Ltd,
added: “Our goal is to provide a world-leading, complementary portfolio of sensors. To do this, we must continually develop innovative technologies ourselves, while also collaborating with fi eld industry-leading technology partners such as Groupe TERA. Their PM sensors ideally complement our PID range, providing a complete solution for air quality management across a broad range of sectors and applications.
“The NextPM sensor breaks new ground in performance and reliability, and we anticipate strong demand from customers in both industrial and environmental applications seeking to optimise air quality and safety in line with local and international standards.”
TERA and ION are aligned in their mission of delivering innovative sensors, backed by unrivalled integration support and service, as well as their vision of preserving the environment through better air quality, and protecting lives. Pascal Kaluzny, Founder and Chief Executive Offi cer of Groupe TERA, commented: “Our partnership with ION Science Ltd enables the distribution of our sensors worldwide, allowing users to benefi t from market-leading sensor performance wherever in the world they are located. Both companies share common goals, with a strong commitment to optimised air quality, and broader environmental considerations. We continue to innovate to deliver the next generation of sensors combining unrivalled accuracy, robustness and ease of use across multiple applications. Founded in 2001 and based in Crolles, France, Groupe TERA is a leading global player in real-time measurement, analysis and evaluation of air quality. It is one of only a handful of companies worldwide operating across the entire air quality value chain, meeting diverse customer needs. Its dedicated laboratory specialises in the analysis of chemical air pollutants across a range of environments, while the company designs, develops and supplies an acclaimed range of innovative sensors for real-time air quality measurement. These are complemented by the company’s innovative professional analysis software which processes the air quality data gathered by its sensors.

The most comprehensive range of refrigerant gas sensors on the market
Innovative Gas Sensing: By constant research and innovation, NET of Italy has developed distinctive and unique technologies and a comprehensive range of sensors for refrigerant gases detection - all microprocessor based, fully calibrated and targeted at different market segments and applications, both commercial and industrial. NET now offers solution to monitor over 40 different refrigerant gases.
• IRNET-Pro, with over 10 years of fi eld application history is NET’s bestselling sensor. Widely used in industrial applications (from cold rooms to landfi ll gas detection to Oil&Gas settings), can reliably detect CO2
(R454, R452) in the lower fl ammable limit range. It features complete calibration over-40°C/+60°C temperature range and SIL2 certifi cation.
• IREF-Pro has been specifi cally developed for the most accurate detection of low ppm concentrations of HFC and HFO gases. It features a powerful black body light source enabling ppm detection of a comprehensive number of gases. It comes fully calibrated for the target gas and is SIL2 certifi ed.
• IREF-Lite offers a lower cost alternative to the ‘Pro’ version, for commercial and light-industrial applications: it is available for A2L refrigerants (R32, R1234yf, R1234ze) in the fl ammable range and for gases used in VRF applications (R410a, R134a) up to 1%vol.
• The Remora module is the newest addition to our range. This very cost effective device has the same features and gas list as the IREF-Lite but it is designed to be integrated directly on chillers and other refrigeration equipment instead of a gas detector. Every aspect of the hardware can be fully tailored on the customer’s criteria and application needs.

Gas sensor specialists continue to improve selectivity and precision
Swiss gas sensor specialists Membrapor strive continuously to improve the selectivity of their sensors to provide even more accurate, selective and safe measurements. This year has been no exception and several enhancements have already come to fruition.
Membrapor upgraded their CH2O/CA-10 sensor by eliminating its cross-sensitivity to methanol. For selective measurements of formaldehyde (CH2O) concentrations in applications with aqueous CH2O solutions that contain methanol as a stabiliser (“Formalin”). Such solutions are typically used for the fi xation or preservation of biological tissue and cells.
The ETO/CA-10’s cross-sensitivity to carbon monoxide (CO) has been reduced. For selective measurements of ethylene oxide (ETO) concentrations in applications where small amounts of CO, possibly due to vehicle traffi c, are present. ETO gas is widely used as a sterilisation agent for a wide range of applications.
Membrapor also launched the AsH3/C-1 and the AsH3/M-1 sensors - two extremely sensitive sensors, which enable the highly toxic gas arsine to be measured in the ppb range. They also designed a gas cap for their compact sensors (7-series). The cap can be used with Membrapor’s digital or analogue electronics as pre-calibrated units.
