Laser PM2.5/PM10 Particle Counter Air Monitor w/ Temp/Humid Data Logger Tester
Key Features
🔬 High-Precision Laser Scattering Technology
Unlike basic air quality monitors that rely on less accurate sensors, this device uses advanced laser scattering principles to detect airborne particles with exceptional accuracy. It measures particles as small as 0.3μm—giving you professional-grade data you can actually trust.
📊 3-Channel Particle Detection
Detects and counts particles across three critical size channels: 0.3μm, 2.5μm, and 10μm. This multi-channel approach gives you a complete picture of your air quality—from the finest ultrafine particles to larger dust and pollen.
🎯 PM2.5 & PM10 Concentration Measurement
Measures PM2.5 and PM10 mass concentration from 0 to 1000μg/m³ with a remarkable accuracy of ±12μg/m³ and resolution of 1μg/m³. Know exactly what you're breathing, not just a vague "good" or "bad" indicator.
📈 999-Group Data Logging with Trend Curve
Stores up to 999 sets of historical data records and displays them as an intuitive trend curve on the screen. Track changes over time, identify patterns, and prove the effectiveness of your air purifiers or ventilation improvements with hard data.
🖥️ 3.2-Inch TFT Full-Color Display
Large, bright, and easy-to-read colour screen shows all your measurements at a glance. No squinting at tiny monochrome LCDs—get clear, instant feedback on your air quality.
🌡️ Built-in Temperature & Humidity Sensor
Monitors ambient temperature (with switchable ℃/℉ units) and relative humidity simultaneously. Perfect for understanding the complete environmental picture—because temperature and humidity affect both comfort and how particles behave in the air.
⚡ Rechargeable Lithium Battery + USB Power
Powered by a built-in rechargeable lithium battery (no disposable batteries needed—saves you money and hassle) with the option to run continuously via external USB power. Never get caught with dead batteries in the middle of a monitoring session.
🔊 Audible Alarm with On/Off Toggle
Set custom alarm thresholds and get audible alerts when particle levels exceed your safety limits. Toggle the alarm sound on or off with a single button press—quiet when you need it, loud when it matters.
🔄 Count & Mass Mode Switching
Switch between counting mode (number of particles per unit volume) and weighing mode (mass concentration in μg/m³) depending on your application. One device, two powerful measurement perspectives.
⏱️ Adjustable Auto-Shutdown & Recording Interval
Set recording intervals from 1 minute up to 8 hours and configure auto-shutdown to preserve battery life. Perfect for long-term unattended monitoring or quick spot checks.
