Advanced Oral Odor Detection: Our device, armed with a precise MEMS sensor and 32 - bit CPU, rapidly and accurately detects VSCs that lead to oral odor. The non-contact, hidden-cartridge design guarantees top-tier hygiene. Inhale deeply, then exhale steadily towards the holes for 3 - 5 seconds at a 1 - cm distance. The large, easy-to-read LCD clearly shows VSC ppm, preheating progress, and detection distance, providing comprehensive data for detailed oral health checks. 4-Level Oral Odor Leves for Oral Health: Our oral odor monitor classifies oral odors into four distinct levels. Level 1 indicates no noticeable smell, Level 2 a faint odor, Level 3 a medium - strong smell, and Level 4 a very intense smell. When using, deeply inhale then exhale steadily towards the holes for 3 - 5 seconds at a 1 - cm distance. Those odor levels are great aid for accurately gauging oral health status, making it perfect for daily personal oral cavity care routine. Innovative One - Key Oral Odor Check: Starting the breath freshness device is a breeze. Simply press and hold the power button for 3 seconds.

Then, inhale deeply, exhale steadily through your open mouth towards the holes for 3 - 5 seconds, 1 cm away, for an instant evaluation of your oral odor. The one-button operation is ideal for convenient at-home or on-the-go oral cavity testing. Portable Oral Odor Monitoring with Long Battery Life: Compact and lightweight, this Oral Odor Monitor is designed for on - the - go use. Its rechargeable battery can last up to 30 days on a single charge. During testing, take a deep breath, exhale steadily towards the holes for 3 - 5 seconds, maintaining a 1 - cm distance. The combination of the precise sensor and 32 - bit CPU ensures quick and reliable detection of VSCs, allowing for continuous oral health tracking wherever you are. Accurate Oral Odor Monitoring Precautions: For reliable results, this oral odor device is not suitable for measuring food-related odors due to their short-lived nature and lack of reference value. Additionally, if you've used mouthwash, perfume, or other chemicals, wait 30 minutes before taking a check.
