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...
Emissions occur during various stages of the glass-making process, precision combustion measurements are therefore critical. We supply a range of advanced solutions designed specifically for the glass industry, meeting the highest standards of quality and reliability. Glass is used for a variety of purposes, and can be shaped, toughened, coloured, laminated or treated to suit specific requirements. Our measurement systems provide accurate combustion monitoring to support these applications.
Environics® Ambient Monitor Calibrator with Ozone Generators facilitate dynamic calibration of ambient air analyzers. These instruments automatically perform zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. All ozone generators are factory calibrated using a NIST traceable ozone standard. The Series 6100, Series 6103 and Series 9100 all meet or exceed U.S. Environmental Protection Agency requirements.

AppliTek’s gas analyzer system allows to monitor and control precisely oxygen levels in the hydrogen feed of the HCl burner. The analyzer system can be equipped with either an electrochemical cell, by alternating Pressure Paramagnetic or with a Tunable Diode Laser (TDL).
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...

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.
Mitigate regulatory risk. Run your AST facilities at peak efficiency. Bulk petroleum facilities face onerous environmental demands. Demands that if not met consistently and with precision, could cost you tens of thousands of dollars per day and even threaten to hobble your operation. Titan automates even the most thorny areas of AST regulatory compliance, from spill prevention and ground water protection, to alarm monitoring and testing that meets API standards. So you`ll be on top of every test & inspection...
A variety of medical devices, such as ventilators, breath analysis equipment and anesthesia delivery monitors require a quick and precise measurement of gas flow.
