Overview
GAO Tek Indoor Air Quality Monitor is designed for comprehensive indoor environmental monitoring. Featuring a 7″ industrial-grade Android touchscreen, it offers modular, customizable sensing for gases (like formaldehyde, CO₂, NO₂, O₃), particles (PM2.5, PM10, PM100), temperature, humidity and more. The alarm thresholds are configurable with audible alerts, and it supports networking via RS485, Wi-Fi, Bluetooth, or 4G for remote monitoring.
Features
- 7-inch TFT industrial Android touch screen with customizable voice prompts.
- Modular plug-and-play sensor platform, no on-site calibration needed.
- High-precision brand sensors with fast response, strong interference resistance, long lifespan.
- Rugged cast aluminum housing—explosion-proof, waterproof, dustproof.
- Network compatible: Wi-Fi, Bluetooth, 4G, RS485 (Modbus), IoT module support.
