WORKSHOP-READY AIR MONITORING: Built for woodworking shops, garages, and industrial spaces, this air quality monitor continuously tracks sawdust, paint fumes, and airborne pollutants during cutting, sanding, and finishing. ADVANCED MULTI-SENSOR SYSTEM: Equipped with next-generation infrared (NDIR) CO₂ sensors for enhanced accuracy and sensitivity—offering far more reliable readings than conventional low-cost air quality monitors. This unit also features an electrochemical HCHO formaldehyde sensor (0–2 mg/m³), semiconductor TVOC sensor (0–5 mg/m³), and laser particle sensors for PM1.0, PM2.5, and PM10 (0–999 μg/m³) REAL-TIME ALERTS & VISUAL INDICATORS: Color-coded air quality levels (green, yellow, red) with audible alarms for CO2, VOCs, particulate matter, and formaldehyde help you quickly identify unsafe working conditions. 7-INCH COLOR LCD DISPLAY: Easy-to-read display with 3 brightness levels shows all air quality metrics in real time, plus temperature (-40° to 211°F) and humidity (0–99% RH) to monitor shop comfort levels. FAST CHARGING & POWER OPTIONS: Built-in 2500mAh lithium-ion battery recharges in just 2 hours for up to 6 hours of cordless use. Can also be used while charging, though continuous plugged-in use may generate slight extra heat that can minimally affect temperature readings—optimal accuracy is achieved during battery operation. USER-FRIENDLY OPERATION: Quick °C/°F switch, 12/24-hour clock adjustment, and brightness controls. Requires a short 2-minute warm-up only when first powered on to calibrate sensors. MULTI-APPLICATION VERSATILITY: Perfect for woodworking shops, finishing areas, warehouses, greenhouses, or home use—anywhere reliable air quality monitoring is needed.
