Maintenance conditions vary depending on the gas conditions. Replacement intervals for the filter and
activated carbon should be determined in accordance with the operating conditions.
• Activated carbon filter life is about 50 hours. (if measured gas contains isopropyl alcohol of
concentration 500 ppm, and flow is 500 ml/min.)
• In case of using the built-in pump or with the aspirator, the activated carbon filter life is about 25
hours.
