- 【Dual-Mode Power Supply】LSENLTY’s newly upgraded plug-in Portable Outdoor Air Quality Monitor supports dual power supply modes: plug-in power and AAA backup batteries, so you don’t need frequent recharging. In case of power failure, it automatically switches to battery emergency mode to deliver round-the-clock uninterrupted air quality values tracking.
- 【3-in-1 All-Purpose Monitoring】This 3-in-1 Air Tester with Temp&Humidity combines three core detection functions: air quality values, temperature and humidity. No need to prepare multiple separate devices. One LSENLTY air quality Tester can fully track ambient air quality fluctuations even under complex surroundings.
- 【Accurate Reminder Function】LSENLTY Portable Outdoor Air Quality Monitor comes with an intelligent notification system. Once air quality values go beyond the preset threshold, the indicator light blinks and the buzzer triggers audio prompts at the same time. The 2.7-inch HD screen delivers real-time notifications, enabling you to grasp surrounding environmental status instantly.
- 【Status Light Operation Guide】State 1: When the Portable Outdoor Air Quality Monitor is plugged in, short-press the “O” button to launch self-check mode. The green light blinks three times, followed by three flashes of the red light. After the flashing sequence finishes, the buzzer beeps and the status light stays lit for three seconds. State 2: When the plug-in air quality Tester is disconnected from mains power, the backup batteries take over operation. If air quality values above 200ppm are detected, the status light turns on, the buzzer sounds, and triple on-screen notifications pop up simultaneously.
- 【High-Precision Sensing Module】This LSENLTY battery-operated Portable Outdoor Air Quality Monitor adopts an upgraded high-precision sensing component with a 2-second fast data refresh rate, and measurement error is tightly controlled within ±5%. This LSENLTY air quality Tester features a detection range of 0–999 ppm (tolerance ±5%); temperature measuring range from -10°C to 50°C / 14°F to 122°F (tolerance ±3%); humidity measuring range 0%–95% RH (tolerance ±5%).
- 【Stable Long-Term Tracking】The 3-in-1 Air Tester with Temp&Humidity is fitted with high-stability sensing parts to sustain steady detection performance long-term. Perfect for outdoor camping, hiking and vacation trips, this unit delivers reliable environmental monitoring and effectively avoids detection failure risks caused by sensor aging.
- 【Multi-Scenario Compatibility】The plug-in air quality Tester with battery backup removes limits on applicable environments. It works perfectly for vacation stays, camping environment inspections and outdoor travel air tracking. Ready for immediate use out of the box with no complicated setup required. This LSENLTY Portable Outdoor Air Quality Monitor can run via power adapter or replaceable AAA batteries, with easy battery swap for long-term hassle-free air quality values monitoring.
