EIA-31,TIA-31 Series Infrared Gas Analyzer

Overview

The EIA-31 and TIA-31 series units use infrared absorption to provide continuous and highly accurate monitoring of composition changes of the specific components of compound gases. The units have few moving parts, provide accurate displays over the long term, and achieve highly stable monitoring. The units also use infrared analysis, which offers superior sensitivity, selectivity, and stability. The units safeguards incorporated into their construction that provide high levels of safety in potentially explosive environments. The units can be used for process control in a variety of industries, including smelting, mining, petrochemical, and biochemistry.

Features

The integration of the analysis and operation instruments allows easy maintenance and inspection.A digital display provides accurate on-site readings.The units provide continuous long-term, stable monitoring thanks to the use of HORIBA-developed chopper monitors, which require no lubrication and have long operating lives.Japanese-made solid filters on all sides and a high-performance output device ensure superior selectabililty, especially with regard to interferant gases.The complete enclosure of such items as the output device cell port, the cell, and the internal piping ensures that they will not be damaged by explosion and thus minimizing the possibility of secondary explosions due to the ignition of sample gases.The units have wide-range transmission capabilities (1 km standard).The series offers four models: the general-use, pressure- and explosion-resistant EIA-31; the low concentration-use, pressure- and explosion-resistant TIA-31; the general-use, internal pressure- and explosion-resistant EIA-31F; and the low concentration-use, internal pressure- and explosion resistant TIA-31F.
