Product Introduction
Specially used for public toilet environment detection, can integrate up to 14 measurement elements simultaneously, and uses NH3, H specially for toilet environments2S sensor, high sensitivity.
The device uses original imported sensors and control chips, featuring high precision, high resolution, and good stability.
Uses a circular curved housing, and with the base we provide, it can be installed on the ceiling or wall-mounted.
