Many large combustion plants are now required to monitor mass emissions of major pollutants and to do so requires an accurate measurement of stack gas velocity. The VCEM 5100 is certified to EN 15267 part 3 QAL 1 for all industrial processes including waste incineration. It has several key advantages, firstly the sensors optics are not in contact with the hot and dusty environment, the VCEM 5100 can monitor gases at temperatures exceeding 10000C and the analyser requires minimal maintenance. The VCEM 5100 can be...

Thin film deposition processes, e.g. reactive PVD (Physical Vapor Deposition), require a repeatable gas flow of the reactive gas to ensure reproducible film properties. With its industry-leading repeatability of < ± 0.15% FS and very small long term drift the Axetris MFC 2100 series supports you in making your equipment stable and easy to use for your customer.
Carbon Dioxide (CO2) lasers are high power lasers, usually used for cutting of ferrous and non-ferrous metals. High-performance gas flow control is a key requirement for achieving high cutting performance with CO2 lasers. Gas flow control plays an important role for mixing key gases at a number of locations with a CO2 laser: Beam Generation: The gas mixture used as the emitting medium usually consists of CO2, He and N2. Most laser manufacturers specify a minimum required purity for the beam generation gas...
Monitoring stack emissions is a fundamental requirement for most industrial processes. Our gas analysers, dust monitors and flow monitors are designed for a wide range of applications and can operate as a fully integrated system or as stand alone instruments.
The medical industry requires the accurate and consistent performance of its equipment. IST’s precise and reliable sensors meet the needs of these applications. Flow is perhaps the most widely used sensor in this industry, controlling medical devices where a gas or fluid is being supplied to a patient, or in cases of patient monitoring. Humidity sensors also have an application in the medical industry in products that control the air present or supplied to the patient.
Thermal mass flowmeters are ideal for Carbon Dioxide metering and mass flow control. Sierra specializes in accurate mass flow measurement and/or control of CO2 gas. Applications range from general industrial process control across numerous industries to Green House Gas monitoring requirements and general research.
Bioreactors and fermentors are used in a variety of biotechnology and industrial applications, e.g. in cell culture or microbiology experiments. A precise control of gas flow is essential for controlling the biological process and to achieve the desired result.
