German manufacturing company WITT-Gasetechnik has optimised its gas analyser ‘PA 7.0’, used for measuring oxygen (O2) and carbon dioxide (CO2) concentrations, with a revamp into a more compact and hygienic design.
Separate chemical, zirconium and infra-red measuring cells have all been integrated into the analyser, which will emit an alarm or switch to a floating contact to interrupt the gas supply, if the limit value is reached.
Added data memory now stores the last 500 measurements, meaning the user can document and analyse all measured results digitally, and the gas-related equipment company has assimilated additional interfaces, such as 24V inputs and outputs as well as relays, with which to integrate the analyser with an existing system.
In some versions, the ’PA 7.0’ can perform a random sample analysis using a sample needle to check the protective gas atmosphere in food packaging.
WITT is hoping the redesign of this device will further infiltrate the food industry and metal processing sector, to help monitor protective and shielding gases.
WITT this year celebrates 70 years in gas analysis and control equipment, having begun with the launch of the world’s first dry flashback arrestor in 1945. Few, including founder Paul Witt, could have foreseen the company’s journey since then, as Managing Director Martin Bender explains in an interview with gasworld.
German gas technology manufacturer Witt is extending its range of fittings and is launching a new version of gas filter 77, including certification for oxygen service by the German Federal Institute for Materials Research and Testing (BAM).
