HCHO TVOC Detector Real-Time

A dedicated household self-test device for formaldehyde (HCHO) and total volatile organic compounds (TVOC), featuring a 3D convection air inlet for improved airflow-driven sensing. Built from white plastic, it runs on two AA batteries (not supplied). No dimensions, weight, or capacity data provided in original material. Calibration is fast and user-initiated; an excessive concentration alarm provides immediate feedback. Not certified for professional or regulatory use — intended solely for indicative home monitoring. Suitable for post-renovation checks, new carpet/furniture evaluation, or seasonal indoor air review.
