Preventing accidents caused by gas leakage is a significant challenge in various production facilities and plants, such as steel manufacturing mills, chemical, petrochemical and other types of facilities. This challenge arises due to the aging of facilities and a decrease in experienced personnel capable of providing safety guidance.
It is of utmost importance to proactively prevent accidents for the well-being and safety of workers, safety of the surrounding environment and residents, and the stable operations of the plant.
▷ One analyzer for monitoring multiple sampling points over a wide area
The switching of multiple sampling points enables the measurement of a wide area with a single analyzer.
▷ Excellent maintainability
Compared to installing many simple sensors, our solution involves only one analyzer. This allows maintenance in a single location, contributing to a reduction of maintenance cost and increased work efficiency.
The analyzer equipped with automatic calibration function that facilitates daily maintenance.
▷ Accurate measurement of gas components across wide range, even at low concentrations
Due to HORIBA's original Cross-Modulation NDIR technology (refer to Fig. 2) adopted to the ENDA-5000 analyzer, it is capable of performing stable and accurate measurements and detecting concentration changes even at low parts per million levels.
