About This
- 【Professional Formaldehyde Detector】 Equipped with a high-precision electrochemical sensor, HCHO Detector delivers accurate formaldehyde measurements with fast response time (T90 <30s). Measuring range: 0-2.50 mg/m³ (Effective: 0-1.00 mg/m³, Resolution: 0.01 mg/m³).
- 【TVOC Air Quality Monitor】The built-in thick-film semiconductor sensor detects the total level of volatile organic compounds in the air, including benzene, carbon monoxide, ammonia, hydrogen, alcohol, and cigarette smoke. TVOC range: 0-10 mg/m³ (Resolution: 0.05 mg/m³).
- 【In-Depth Data on a Vibrant Display】The 2.8-inch TFT color screen shows clear readings. While the main screen shows current levels, you can dive into test interfaces for each pollutant to view real-time data, 10-second/60-second averages, and MAX values. The built-in, foldable stand on the back allows you to place tvoc tester conveniently on any desk or table for continuous, hands-free monitoring.
- 【Customizable Alerts with Hazard Index】Stay informed with fully adjustable alarm thresholds for HCHO, TVOC, and the comprehensive Hazard Index—a combined indicator that gives you a complete picture of your indoor air quality at a glance, helping you safeguard your family's well-being.
- 【Data Recording & Long-Lasting Battery】The REC function lets you record data at user-set intervals (10/20/30 min) for up to 3 hours. Auto power-off function (5-30 min or OFF) helps conserve energy when not in use. Powered by a 2000mAh rechargeable battery, this tvoc hcho detector operates continuously for up to 15 hours on a single charge.

Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
