Measurement and Testing Introducing the world’s first in situ hydrogen analysers


Monitoring Hydrogen in situ has been perceived as being impossible. Not anymore! As the first in the world, NEO Monitors has developed a solution for measuring hydrogen in situ using traditional infrared tunable diode laser absorption spectroscopy. The underlying technology has already been used successfully for a wide range of industrial applications.


NEO Monitors’ LaserGas™ II SP H2 now opens the door to new opportunities in process control with exceptional response time. Not only that; the cost of monitoring will be significantly reduced compared to traditional monitoring methods. LaserGas™ II SP H2 is accompanied by LaserGas™ II MP H2, an extractive multi-pass solution for applications with higher demands on sensitivity or wherever an in-situ solution is not feasible.


‘We have been working towards this moment for years, building brick by brick. It has been perceived as impossible, but we’ve done it anyway!’, CEO of NEO Monitors, Ketil Gorm Paulsen, says. ‘The hydrogen molecule has for a long time been considered as non-absorbing in the infrared region. This is de facto incorrect and by redesigning our analysers we have achieved an unprecedented sensitivity down to the tiny absorption levels required to monitor Hydrogen. Our new analyser is the perfect solution for many applications and opens up for better process control in reactive, toxic and corrosive gas streams.’


NEO Monitors’ new solution will fit in any chemical plant or refinery anywhere in the world. The oil and gas industry, and other chemical production will benefit from real-time measurements of hydrogen levels. LaserGas™ II SP and MP H2 provides contactless and continuous monitoring of hydrogen concentrations with a response times of less than 2 or 20 seconds, respectively. The solution maintains all advantages of the well-proven, trusted and flexible LaserGas™ technology. LaserGas™ II SP and MP H2 can detect leakages and increase the efficiency of process controls and increase security.


LaserGas™ II SP and MP H2 will ensure problem-free operations for refineries and chemical plants, thanks to the fast response and low maintenance requirements. NEO’s new analysers can be used for detection of leakages, improved process control and a range of other applications where continuous Hydrogen monitoring is necessary. Ultimately, LaserGas™ II H2 can be the direct reason accidents are prevented, Paulsen says.


‘Because the LaserGas™ technology has no zero drift, a continuous internal health check option, and does not need any consumables the maintenance cost of our new analysers is very low’. For More Info, email:


46924pr@reply-direct.com Study confirms which lightning detection technology delivers the most precise measurements


Sensors built by Vaisala detect over 98% of all cloud-to-ground lightning flashes. The network of sensors locate these ground lightning flashes with a median accuracy of better than 200 metres. Based on results from validation studies performed in the US, this was the conclusion reached by Stephan Thern, Head of Siemens Lightning Information Service (BLIDS), which has used Vaisala’s lightning sensors since 2003.


Since 1991, Siemens has operated a comprehensive lightning flash information service (BLIDS) that is now accessed by over 10,000 users. With BLIDS, utility companies, turbine operators and insurance companies have access to real-time data, can issue alert messages in advance, identify risks and fault causes, and even shut down airports or protect wind turbine service technicians. In 2016 alone, the service registered 432,000 cloud-to-ground lightning flashes in Germany. Siemens is currently using the latest Vaisala sensor model based on 40 years of experience in lightning detection. Siemens and Vaisala are members of EUCLID, a collaboration of national lightning detection network operators operating 160 sensors across 27 European countries.

With its latest sensors, Vaisala has made further progress in the detection of cloud lightning. As confirmed by validation studies using data from the National Lightning Detection Network (NLDN) in the US, Vaisala’s sensors can detect the difference between a ground stroke and cloud lightning with better than 90% accuracy.


“The large voltage spikes and electrical current associated with cloud-to-ground lightning create a variety of hazards for both people and property. Due to these dangers, knowing the precise location and strength of each cloud-to-ground stroke is hugely beneficial to a variety of commercial and industrial applications,” says Dr. Ryan Said, Research Scientist at Vaisala.


“For example, a utility operator may want to know if a transmission line fault was caused by a lightning stroke. Or a wind farm operator may want to check specific turbines for damage after a thunderstorm passes overhead. In these types of applications, the quality of the lightning data translates directly to operational efficiency. In particular, users benefit from precise locations and reliable classification of each event. If a ground stroke is misclassified as a cloud pulse or is not precisely located, the user may not perform a necessary inspection to check for damage, leading to increased downtime.”


“Vaisala’s lightning detection system delivers the best performance,” states Thern. “Thanks to the precise measurement technology, the sensors can be set up at distances of 350 kilometres apart without any problem, which significantly reduces the installation, operating and maintenance costs. By 2020 we will set up six new stations with Vaisala sensors and continue to combine the lightning and weather data in order to be able to be able to predict the direction of storm fronts even better.”

Calculated power plant pH with conductivity


determination based on


power plant conductivity’ The correlation between conductivity of ammonia and pH has been used for decades to compare cycle chemistry measurements. With a decrease in personnel overseeing power plant cycle chemistry today, there is a greater reliance on on-line instrumentation. Calculated pH can be more accurate and reliable than high purity pH measured with a conventional glass electrode.


The calculated pH approach can be highly useful because conductivity sensors require far less maintenance than pH sensors. By combining specific conductivity measurement with cation conductivity, a solutions pH can be calculated. For normal plant operations, this is more accurate than using a conventional glass electrode. If degassed cation conductivity is also measured, Dissolved Carbon Dioxide can be determined.


This simplicity also extends to installation, start-up, calibration and maintenance, and each one of these areas can represent significant savings in time and production downtime.
