CAC Gas & Instrumentation products

CAC Gas offers a wide range of certified reference materials including specialty gas mixtures, liquids, and liquefied gas standards.

CAC GAS provides calibration and bump test solutions to help ensure safety of workers through the accuracy of your personal, hand-held, vehicle mounted, or fixed gas detection instruments. Whether you require a single, disposable cylinder or a complete gas distribution system connecting multiple gas mixtures to hundreds of docking stations, CAC GAS has the solution.

With an unparalleled history of representative sampling, repeatability, and accuracy, the Welker GSS-4PM Gas Sampling System has proven itself to be the superior composite sampling solution for natural gas—wet or dry. clean or dirty. The self-purging probe-mounted system collects fresh samples proportional to flow or time. The Vanishing Chamber" collection cup ensures your samples will be as representative and accurate as the results of an online analyzer.

The Welker HGS Heated Gas Sampler is a composite sampling solution for natural gas at or near the hydrocarbon dew point The HGS maintains the sampling equipment above the hydrocarbon dew point to ensure composite samples are representative and not distorted by phase change. Connect the HGS to a sample probe to collect fresh samples proportional to flow or time.

The most powerful in GasMix family, this gas mixer/diluter can automatically prepare and deliver complex gases to virtually all kinds of analytical instruments, reactors, or sensors. The principle is based on the dynamic mixture of 5 to 16 standard gases (customized systems for up to 20 gases are possible). No need for manual computations - for every desired output concentration the software does automatic calculation of dilution and span gas flows, even for very complex mixtures.

The intelligent mixer, diluter & injector. To save money and gain in flexibility, many laboratories use Aiolos - dynamic gas mixer from AlyTech - to perform multi-point calibration, linearity checks, LOQ/LOD validation. The Aiolos II is the latest generation of this popular product in GasMix™ family designed and produced by AlyTech since over TOyears. By mixing and/or diluting two to fourgases the system generates calibration gas on site at the desired concentration, even to very low levels.

GasMix ATMO calibration gas generator is well suited for air monitoring agencies, and not only. Developed in collaboration with French air monitoring agencies, this unique system automates multi-point calibration, repeatability and linearity checks in compliance with EN standards. Typical air monitors analyzers, like S02, NO-NOx and CO analyzers, are calibrated all 3 in the row by switching span gases, and future diluting it with air zero gas. The ATMO helps operators saving time and cost of routine checks, while assuring high accuracy and traceability.

The Precision Hydrogen generators are designed to provide the gas needed for detectors requiring Hydrogen fuel gas, such as FID. One generator is capable of supplying multiple detectors, and are available in various flow rates to ideally suit individual customers` needs.
