Advanced Oral Odor Detection: Our device features a precise MEMS sensor and 32-bit CPU to rapidly and accurately detect volatile sulfur compounds (VSCs) associated with oral odor. The non-contact, hidden-cartridge design ensures high hygiene standards. Inhale deeply, then exhale steadily toward the sensor holes for 3 to 5 seconds at a distance of 1 cm. 4-Level Oral Odor Classification for Oral Health: The oral odor monitor categorizes breath into four distinct levels. Level 1 indicates no noticeable odor, Level 2 a faint odor, Level 3 a medium-strong odor, and Level 4 a very strong odor. For testing, inhale deeply and exhale steadily toward the sensor holes for 3 to 5 seconds from a distance of 1 cm. Innovative One-Key Oral Odor Check: Operating the breath freshness device is simple. Press and hold the power button for 3 seconds to activate. The device enters a 9-second preheating phase, indicated by a vibration and flashing blue light. After preheating, inhale deeply and exhale steadily through your mouth toward the sensor holes for 3 to 5 seconds at a 1 cm distance to receive an instant breath evaluation. The one-button design allows for convenient at-home or portable oral testing. User-Friendly Data Interpretation: The Oral Odor Monitor provides clear, easy-to-understand results using a 4-level classification system. When oral odor exceeds normal levels, the LCD screen turns red and the device vibrates, prompting users to consider adjustments to diet or oral hygiene routines to support better breath and overall oral health. Accurate Oral Odor Monitoring Precautions: For best results, avoid using the device immediately after consuming food, as food-related odors are temporary and may not provide a reliable assessment of overall oral health.
