In the following article we outline the environmental and health issues associated with NOx, and emphasise the importance of monitoring nitrogen oxides. We also describe the factors affecting the choice of measurement technology, and explain some of the issues that should be addressed by chemiluminescence analysers. Download the full Technical
The UK based gas analyser manufacturer Signal Group has announced the appointment of Stephane Canadas as Sales and Marketing Manager. “In recent years we have invested heavily in product development, so this is a great time for Stephane to join the company,” comments Signal MD James Clements. “In many respects,
The technology development team at Signal Group have announced the launch of yet another market leading innovation for its S4 gas analysers – a completely detachable screen. “We noticed that it was either inconvenient or impossible for many of our customers to be physically next to their analysers in order
Continuous Emission Monitoring (CEMs) operators are already familiar with the need to calibrate their stack analysers using certified calibration gases. Frequent calibration against an accurate certified gas ensures that the measurements from the stack will be as accurate as the calibration gas provided that the analysers don’t drift in between
As a developer and manufacturer of gas analysers since 1977, Signal Group staff possess a high level of knowledge in the sampling and analysis of gases in industrial processes and emissions. The company is therefore able to help in the development of international test standards, and was recently invited to
As one of the world’s leading manufacturers of VOC monitoring equipment, Signal Group performs a vital role in helping to protect the environment from harmful emissions. Volatile organic compounds (VOCs) are harmful to both health and the environment, so the management of risks associated with VOCs necessitates accurate and reliable
As a British developer and manufacturer of gas analysers, Signal Group follows the emergence of international Standards very closely. This is because Standards ensure that monitors are fit for purpose, and also because regulators require operators to employ suitably certified equipment. Signal Group is therefore delighted to confirm that the
As part of the company’s commitment to quality and reliability, Signal Group regularly runs service and technical training courses for its international distributors. The most recent to benefit from this were four visitors from Signal’s Chinese distributor, Beijing Leshi Alliance Tech. The training covered Signal’s most popular products including portable
The S4 PULSAR range of NDIR multi-gas analysers are available in 1, 2, 3, 4 or 5 gas channel configurations, offering high levels of performance with monitoring options including carbon dioxide, methane, nitric oxide, nitrous oxide, sulphur dioxide, hydrogen chloride and oxygen. The flexibility and advanced capabilities of these analysers
Signal Group’s highly accurate but simple to operate Gas Divider, the 821S is designed for testing the linearity and calibration of almost any gas analyser. This instrument only requires one calibration gas and a zero gas in order to conduct a full range calibration check. The linearity of all gas
