Analyser instrument co distributes a gas analyzer manufactured by fuji electric company. Fuji electric company developed the first infrared gas analyser in japan to use mass flow sensors. These gas analysers are commonly used to monitor the atmosphere to help maintain a cleaner and natural environment. Specifications of the gas analyzer available from analyser instrument company: gas analyser [zkj] is capable of measuring the concentrations of no2, so2, co2, co, ch4 and o2 components in a sample gas mixture. Non-dispersion infrared method [ndir] measures no, so2, co2, co and ch4, while a paramagnetic method sensor or external mount type zirconia method sensors measure o2. A maximum of five components including o2 [maximum four components except for o2 measurement] are simultaneously measurable. Infrared ray method detection block makes the measurement, which is hardly affected by interfering components. In addition, a built in microprocessor and a large size liquid crystal display is equipped for easier operation, higher accuracy and more functions.
