Photoacoustic Spectroscopy (PAS) gas instruments were pioneered and perfected by Innova®. With PAS, the absorption (proportional to the concentration) is measured directly and not relative to a background, making PAS highly accurate and stable. Furthermore, all gases and vapor in small volumes can be monitored sequentially in a single measurement chamber as it is possible to detect up to five substances and humidity to be monitored individually. In a PAS instrument, the gas to be measured is irradiated by modulated infrared light of a pre-selected wavelength. The gas molecules absorb some...

Sulfur Hexafluoride (SF6) is one of the most potent greenhouse gases, with a Global Warming potential of more than 22,000 times than that of CO2. Over the past decades, manufacturers have replaced oil high-voltage switch gears with SF6-insulated units. Today, the power utility industry uses roughly 80% of all SF6 produced worldwide. Photoacoustic infrared spectroscopy is actually listed as the state-of-the-art and most sensitive technique for quantitative tightness test by the reference document in the industry: SF6 Tightness Guide, CIGRE Technical Brochure 430 - WG B3.18. The low detection...

Industrial Hygiene Industrial hygiene (IH) is the science of anticipating, recognizing, evaluating, and controlling workplace conditions that may cause workers’ injury or illness. Industrial hygienists use environmental monitoring and analytical methods to detect the extent of worker exposure and employ engineering, work practice controls, and other methods to control potential health hazards. Innova Photoacoustic Gas Monitors have a long track record of successful deployments which encompass a broad range of applications in the fields of Industrial Hygiene (or Occupational Safetyand...

Refrigerant Gas Leak Detection Refrigerant gas leak detection is becoming a high priority due to the risk to the environment, the increasing price of refrigerant gas, and the high price for repair of major leaks. The need for accurate refrigerant gas detection is also driven by tightening regulations such as the European F-Gas Directive and EN378 legislation. Andros 6552 NDIR gas module with two gas channels can be applied to any type or combination of refrigeration systems that may employ CFC, HFC, HCFCs and CO2. power consumption and low maintenance designed to meet or exceed EN 14624,...

Soil Science Emissions Greenhouse gas (GHG) emissions studied in soil science include: soil respiration and biomass degradation produce CO2 and CH4 and Nitrogen inputs from fertilizers lead to emission of N2O and NH3. The most common, least expensive method for measuring GHG fluxes involves periodic gas sampling from static flux-chambers: the emission rate (or efflux) is derived from the concentration increase. Innova 1512 monitor enables the parallel reading of up to 5 gas concentrations plus water vapor. logs are conveniently stored in the internal memory and can be easily analyzed using...
