14 Gas Detection


How can we help identifying natural gas leaks when H2


is added?


TBM and THT are the most commonly used odorants to make odourless natural gas smell, so that people realise there is a gas leak. However, control of these odorants is necessary to maintain their effectiveness. Only last year, Sensorix offered its electrochemical (EC) gas sensors for mercaptan and THT detection - Sensorix TBM 50 and Sensorix THT 100.


But due to various power to gas initiatives, more and more H2 with high-performance gas sensors and no H2


will be added to natural gas. For this reason, a gas measurement device interference is required. We are very pleased to confi rm that the Sensorix TBM 50 is


already suited for this application. To complete our respective range of sensors, we have developed the Sensorix THT 100 low H2 we now offer a perfect solution for the detection of mercaptans and THT in natural gas with added H2


. The Sensorix TBM 50 detects mercaptans with zero cross sensitivity towards H2 , CO, H2 S, THT and is ready for use in H2 containing natural gas (“power to gas”). The Sensorix TBM 50 gas sensor has


excellent repeatability (standard deviation of sensitivity = 0.5 % for 10 consecutive measurements at 10 mg/m³ TBM). It also shows excellent baseline stability from -10 to 40°C and in changing humidity (<0.1 mg/m³) and its unbiased operation will increase battery life in your portable instrument.


The 3-electrode sensor, Sensorix THT 100 low H2 is suitable for power-to-gas applications because it has a very low H2 interference (THT signal only 1 mg/m3


interference and it requires 300 mV bias. All sensors are available in various standard formats - 4S, 7S, Mini, Classic, Smart, as well as in customer specifi c mechanical adaptations. More information online: ilmt.co/PL/4mnx

Gas sensor modules feature state-of-the-art solid polymer sensor technology


EC Sense offers the TB600B and TB600C Gas Sensor Modules now with an I2C output. These sensor modules combine cutting-edge solid polymer sensor technology with a sophisticated circuit board, providing users with a simple and easy-to-use solution for gas sensing applications. These sensors were featured on the EC Sense stand at the recent Sensor + Test stand in Nuremberg.


The sensor module is designed to make gas sensing easy for users, with its small sensor signal transformed into a standardised digital output. The module detects gas, temperature, and humidity simultaneously, providing a low-power, compact, and reliable solution for any gas detection needs.


The heart of the sensor module is a solid polymer electrochemical gas sensor, a revolutionary innovation in the fi eld of electrochemical detection. The technology is based on the principle of electrochemical catalytic reaction, with the target gas generating a sensor signal that is directly proportional to the gas concentration. The EC Sense solid polymer sensors are small, robust, and reliable, have a fast response time, and consume no power with a long lifetime. They have a sleep mode and can be recalibrated by sending a command.


Dräger has launched the UCF FireCore, a hands-free thermal imaging camera that displays live-action imagery into the Dräger FPS 7000 full face mask. The UCF FireCore gives fi refi ghters continuous vision in the low-visibility, high-risk, and unfamiliar environments that emergencies often present. With IP67 certifi cation, the UCF FireCore is resistant to water and dust, with lithium-ion batteries guaranteeing safety over long durations. The batteries can be charged easily both in the fi re vehicle, and at the fi re station, prior to being deployed.


The camera can be fi tted to any model, shape or size of helmet through a simple bracket, and is fully detachable, allowing fi refi ghters to extend their vision in diffi cult-to-reach areas, and around corners, to enhance situational awareness and spot risks before they present further hazards. When mounted, the viewing angle can be fully adjusted, providing fi refi ghters with the fl exibility to adapt to emergency situations in a matter of seconds.


Near Field Communication (NFC) technology enables the camera to connect to the FPS in-mask display, or transfer the UCF FireCore from one helmet to another. This helps emergency personnel to pass on life-saving technology from one task force to the other – even at the scene of an emergency. This is achieved by holding the thermal imaging camera in close proximity to the in-mask display, before mounting on the helmet.


Liz Milward, Marketing Manager, Emergency and Rescue Services at Dräger Safety UK, says that the release of the UCF FireCore will speed up search and rescue missions and improve fi refi ghter orientation in the most diffi cult conditions: “With fl ames, smoke and darkness impairing vision in high- risk environments, improving situational awareness and enhancing fi refi ghter orientation is critical if we are to protect the lives of fi refi ghters in the most dangerous environments.

Proven combustion analyser upgraded to include refrigerant leak detection


Crowcon recently announced an additional capability of refrigerant leak detection to their Sprint Pro Combustion Analyzer’s already considerable capabilities. Sprint Pro is a multi-function combustion analyser widely used for determining CO/CO2/NOx ratios. This innovation eliminates the necessity to carry and operate a separate, standalone leak detector, increasing workfl ow effi ciency and cost-effectiveness. Operators can now save time and money while obtaining superior leak detection data.


The Sprint Pro Refrigerant Leak Probe has been developed to meet the stringent standards set by HVAC/R professionals who require a high level of precision and effi ciency in their leak detection processes. This upgrade improves the versatility of Sprint Pro models 2-6* thanks to a highly convenient DC Jack connection, enabling tailored customisation to meet end users’ specifi c needs.


The device is an all-in-one solution that combines combustion analysis with refrigerant leak detection, providing a complete solution for operators’ HVAC and refrigeration needs in a single unit. It detects all ubiquitous refrigerant gases ensuring it is catering to a wide range of applications. The Sprint Pro features a fl exible goose-neck with LED Searchlight: Its fl exible goose-neck design enables users to easily access and inspect poorly lit and hard-to-reach areas. The device integrates seamlessly with the Sprint-Pro system, providing both optical and audible alarms for immediate alerts. With its outstanding sensitivity level of less than 5 grams per annum (g/annum) for leak rates, this probe can be relied on to pinpoint even the smallest refrigerant leaks with precision.
