PM2.5 Indoor Air Quality Monitor – Real-Time HCHO/TVOC/PM Detection for Safer Indoor Environments

Product Overview: Keep your indoor environment safe with the PM2.5 Indoor Air Quality Monitor, designed to measure various air quality metrics in real-time. Equipped with high-precision sensors, this handheld device detects PM1.0, PM2.5, and PM10 dust particles, as well as harmful gases like HCHO (formaldehyde) and TVOC (total volatile organic compounds). Ideal for home, office, or car use, this monitor is a versatile solution for maintaining a healthy indoor environment.

Key Features PM2.5 Indoor Air Quality Monitor:

Multi-Parameter Monitoring: Accurately measures PM1.0, PM2.5, and PM10 particles, as well as HCHO and TVOC levels. Additional metrics include temperature and humidity for a comprehensive air quality analysis.
High-Definition LCD Display: A 2.8-inch color LCD screen provides clear, easy-to-read data, even in low light conditions.
Smart App Connectivity: Syncs with a mobile app for real-time data tracking, historical records, and trend analysis. Ideal for monitoring changes over time to assess long-term air quality.
Advanced Sensors: Includes electrochemical sensors for HCHO, laser sensors for PM2.5, and temperature difference compensation for accurate data in varying environments.
Portable Design: Compact, lightweight (224g), and easy to carry, powered by a 1200mAh rechargeable battery, making it ideal for on-the-go air quality checks.

Air Tricorder 2 – The Ultra Portable, Personal PM2.5 Air Quality Monitor index AQI

Ultra Portability

First we added an internal battery so no more need to plug it into a powerbank on the go. You can enjoy using the Air Tricorder 2 for several hours of continual use on a single charge, and when it runs out of juice just plug it in through the USB-C port on the side to charge it up.

Next, we have shrunk down all the electronics by over 50% in thickness, so now the Air Tricorder 2 is about the size of a deck of cards; it will easily fit into your pocket so you can easily take it with you on the go.

Easy to understand AQI Monitoring

What sets Air Tricorder apart from many devices on the market is our instantaneous AQI score, based on the US EPA AQI scale. The Air Tricorder samples the air every 0.5 seconds and then calculates out the AQI severity based on US standards. Many devices only display a raw PM2.5 concentration value and leave it up to you to figure out if it’s good or bad. Or some products use the Chinese AQI scale, which we have found to be more lenient when it comes to reporting bad air quality.

To ensure that our devices are accurate we use quality laser based particle sensors that can detect PM2.5 Pm10 and PM1.0 particulates in the air. The sensors come calibrated from the factory and have been tested by US EPA for accuracy in field trials. Many of the cheaper AQI monitors on the market use infrared sensors which we have found to be woefully inaccurate.

We have increased the size of the screen by 30% over the original Air Tricorder so that it’s even easier to see than ever before.

Along with these big improvements we have packaged everything inside of a sleek case, and to stay environmentally conscious we injected molded our power buttons out of drinking water bottle caps.
