Product Details

TOMONARI Pipi Ventilation-kun TOMO-01 CO2 Ventilation Monitor Carbon Dioxide Concentration Meter

This is a high-performance CO2 ventilation monitor equipped with an NDIR sensor recommended by the Ministry of Economy, Trade and Industry, and is used in all 600 classrooms at a prestigious private university.
I purchased it a few years ago but barely used it, so I am selling it.
List price: ¥14,080 (tax included)

I purchased it from the official TOMONARI store on Amazon, but only used it a few times and kept it in storage at home.
Operation has been confirmed.

I have discarded the box, so I will carefully wrap it in bubble wrap and ship it in a Yu-Packet Plus box.
Please only purchase if you understand that this is a used item and has been stored at home. No returns will be accepted.

Immediate purchase OK.
Price negotiation not possible.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
