法國（阿萊爾科）公司是法國製造氣體(ti) 分析和取樣儀(yi) 器的廠商，用於(yu) 氣體(ti) 的製造和燃燒的控製：氧氣，H2, CO, CO2 和 H2O分析儀(yi) ；ARELCO石油產(chan) 品物理性能分析儀(yi) ；ARELCO熱量計和Wobbe測量儀(yi) ；灰塵，細菌，有毒氣體(ti) 取樣儀(yi) 。

The oxygen analyzer ARELCO ARC models ZOA 100 use a zirconium oxide detector with gaseous distribution. This technique allows to insure a continuous operation, or intermittent, with a reduced maintenance at least.
The ZOA 100, in all its versions, addresses the demanding applications.
The oxygen analyser from ARELCO A.R.C. model TOA MP - R integrates a maintenance free sealed electrochemical sensor and a complete new microprocessor electronics.
