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.
