【Multifunctional & Formaldehyde Detector】 Measures 8 key parameters for comprehensive air quality control: Formaldehyde (HCHO), Volatile Organic Compounds (TVOC), Particle Matter (PM10/PM2.5/PM1.0), Temperature (in ℃), Humidity (in %). Safeguards family health.For more accurate readings, it is recommended to close doors and windows and let the device operate for 15 minutes. When using for the first time or after long-term storage, please place it in a ventilated environment for at least 1 hour to ensure data accuracy. 【Built-in Authentic Sensors & Sound Algorithms】This detector is equipped with multi-layer filtered electrochemical sensors, which eliminate factors affecting formaldehyde concentration. The release rate of formaldehyde is mainly related to temperature. Its built-in AD smart chip performs real-time calibration of formaldehyde data based on differences in air temperature. 【EPA Health Indicator Display】 Features an LCD color screen with EPA health grading: Good (Green), Slight Pollution (Yellow), Severe Pollution (Red). Displays real-time air quality with average values and trend curves for each parameter to facilitate informed decisions. 【Audio-Visual Alarms】 Provides real-time monitoring with dynamic risk-level display. Triggers audible buzzer and interface color changes when data exceeds normal ranges, alerting users to potential risks promptly. 【User-Friendly Operation】 Built-in 1500mAh rechargeable battery (USB cable included) offers 4-5 hours of standby time. Easy one-button power on/off operation for hassle-free use. 【Wide Application】 Portable intelligent monitor detects harmful substances like HCHO and TVOC in various environments: home, office, car, hotel, kitchen, bedroom, etc. Introducing the air quality tester, a sophisticated air quality monitor designed to safeguard the health of families, especially those with elderly members, children, and pregnant women. This portable formaldehyde detector and reliable hcho detector is an essential tool for renters, new house renovators, lab scholars, and individuals moving to a new home. As a versatile air quality monitor, it meticulously evaluates indoor air by integrating functions to monitor temperature, humidity, VOC, formaldehyde, and PM2.5 levels.
