COMPACT TYPE GAS ANALYZER DATA SHEET ZSVS OVERVIEW The compact type gas analyzer with built-in pump and filter is intended for heat treat furnace, plant cultivation, and research-purpose chemical analysis. With the gas extractor, either simplified measurement probe (non-fixed type) or continuous measurement probe (fixed type) is selectable at option. Since a high-sensitivity single-beam mass flow controller is adopted for the infrared sensor, long-term stability and maintainability are excellent. FEATURES 1. Gas concentrations of 4 components measurable simultaneously and continuously (Note).Concentrations of max. 3 gas components among CO2, CO and CH4 are continuously measurable with the infrared sensor, and that of O2 is continuously measurable with galvanic cell type oxygen sensor. 2. Standard with 3-range analyzer Measurement can be performed over a broad range using the range selector key. 3. Compact type small and easy to use. The compact body with built-in pump and membrane filter is easy to carry and install. Operation is easier because operation keys and display unit are all gathered in the analyzing block. 4. A rich variety of standard functions incorporated. Max. 8-channel outputs are allowed including instantaneous concentration value, O2-corrected value, O2-corrected moving average value and CP calculation value outputs. (Note) For continuous measurement, the standard requirements for sample gas (shown on page 3) need to be met, and zero/span calibrations and membrane filter replacement are required periodically.
