Sanwa Supply PM2.5 Measurer CHE-PM25

To all potential buyers:
As I am a smoker, all items I list will have a cigarette odor. Please understand this before purchasing.

Manufacturer: Sanwa Supply
Product Name: PM2.5 Monitor
Model Number: CHE-PM25
Accessories: Instruction manual included. USB-C cable not included.

This item was purchased new on Amazon in 2022.
As the original USB-C cable was lost, I will include a different one from my personal belongings.
The adapter has been used a few times, and the cable is new.
I have confirmed that the battery can be fully discharged and recharged three times using the included adapter and cable.
Full charging takes approximately 3 hours, and continuous operation on a full charge lasts approximately 4.5 hours.
Please note that USB-C cables, even if they have the same shape, have various standards for data transfer speeds and power delivery capabilities. Due to compatibility issues, it is possible that your usual charging cable may not work, so please be aware of this.

The main unit was used for about one month to consider ventilation equipment placement in a room dedicated to spray painting at my home, and has been stored since then.
The screen display changes shown in the photos are from normal indoor conditions and after smoking a cigarette.
The sensor should function normally.
There are no scratches from drops or impacts, but there is some paint residue on the buttons where I touched the unit with paint on my hands. Please check the photos for details.

The item is already packed with bubble wrap and a box, so I will ship it the day after your purchase. Thank you!
