For over 40 years, Sierra has designed and manufactured a wide range of today’s most advanced digital gas flowmeters and controllers for reasearchers and systems integrators, including a high-flow, high-pressure gas flowmeter with a complete suite of digital protocols for network integration.
The purity of a gas is an indication of the amount of other gases contained in it. A high purity refers to a low amount of other gases. High purity gas are considered to be of better quality and are generally more expensive. The purity of the gas can be expressed as a percentage or as a decimal fraction. Applications for checking the purity of the gases across different industrial sectors by air separation plants, cryogenic facilities, the quality control of industrial gases to the steel mills, etc.
calibration gas , British specialty gases company, with a local North Africa presence.
We can supply you with high quality gas mixtures for a wide range of applications including Environmental Monitoring, Gas Detection, Mud Logging, Laser Cutting, and Laboratory Analysis. Our gas mixtures are used in the Oil, Gas and Petrochemical industries
Our main focus is to give our customers gravimetrically produced, high precision calibration gas mixtures conforming to ISO 6142, along with a range of high purity gases...
The gas generators for calibration based on the use of “Method of Permeation Tubes.”. The permeation tubes are sealed capsules containing a small amount of the component that is in contact with a permeable membrane stable. The permeation through the membrane produces a vapor of the compound of the component of small quantity, very stable as a stream in time. This permeate stream by mixing with a dilution gas controlled and precise (for example nitrogen) creates a mixture in track at the desired...
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
Gas Chromatography requires a stable repeatable flow of the carrier gas with negligible temperature drift. The Axetris MFC provides excellent control of the gas flow resulting in sharp peaks and high resolution of the chromatograms. Multiple calibrations allow the control of Helium, Hydrogen or Nitrogen. Due to the high turn down ratio of 1000:1 and more, a broad range of flows can be controlled.
If you use compressed breathing air it is essential to monitor for contaminants including carbon monoxide (CO), carbon dioxide (CO2) and volatile organic compounds (VOCs) as well as oil mist and water vapour. Some people spot-check their compressed air quarterly using colorimetric tubes, but it is safer to test the air continuously. If you are operating or servicing equipment containing fluorinated greenhouse gas (F gas) in refrigeration, air conditioning and fire protection systems you need to adhere to requireme...
Emission monitoring plays critical roles in a number of diverse industrial processes. AMETEK Land provides expert solutions to support product quality, process efficiency and safety. Our industry-leading gas monitors deliver essential data for industry sectors including metals, non-wovens, paper and plastics.
Sierra designs and manufactures a wide range of today’s most advanced analog and digital gas flowmeters and controllers, including a high-pressure gas flowmeter. For gas mixing and blending applications, accuracy and precision control and measurement are always a central requirement. Sierra’s precise flow meters and controls provide end-users with high performance in gas mixing and blending applications like creating artificial atmospheres, gas mixing in manufacturing, inerting and gas chromatography.
The quality of compressed breathing gases for aircraft, diving and marine has very tight limits imposed by bodies such as NATO and national bodies such as MOD. The test requirements are for contaminants such as CO, CO2, Total VOC, CFCs and halogenated hydrocarbons, as well as H2O and O2 content.
Analox equipment is trusted by over 17 submarine nations on their military fleet. Coupled with our expertise in hostile environmental monitoring, we’re the only choice for your submersible gas monitoring needs. Whether operating a tourist submarine, a research submersible or private sub we can assist you with tailor-made equipment for your environmental O2 and CO2 monitoring to ensure operations run smoothly and safely for all onboard.
Sierra is an expert in the control of high flows of gases. With our large and powerful control valves and PID valve control, Sierra`s mass flow controllers, with industry-best low pressure drop, can control much higher flows than equivalent flow controllers with minimal pressure drop requirements.
Levels of of hydrogen in the gas vent of the HCl burner can be measured by means of AppliTek’s thermal conductivity analyzer system. The analyzer system is suited for use in hazardous environments and meets ATEX or NEC500 compliance standards.
Gas monitors controlling heat treatment of metals. Endothermic gas is a mixture of carbon monoxide, carbon dioxide, methane and other gases that is required for hardening or carburising of steel. By carefully controlling the amounts of each gas and the temperature in the treatment furnace, the steel surface can be hardened to provide long lasting components such as gears and tools.
