[NEVER USED] Portable CO tester with digital LED display, multi-function carbon monoxide detector, electrochemical temperature and humidity tester, home air quality tester,

Product never used, packaging damaged during transport. Unopened product, repackaged in our warehouses, in perfect working condition, warranty available.

【Compact and Elegant】: Compact design, simple and elegant appearance, lightweight and easy to carry. Porous 3D housing with multiple ventilation holes designed for real-time airflow. The sensor is in full contact with the air, ensuring highly sensitive and accurate detection of fine particles.

【Digital LED Display】: Digital LED screen with an ultra-wide viewing angle for easy reading at a glance. Features automatic brightness adjustment based on ambient light for a clear display without being harsh.

【CO, Temperature, and Humidity Measurement】: Built-in high-performance electrochemical NDIR chip for carbon monoxide detection, enabling real-time monitoring of CO concentration, even in challenging environments. High sensitivity, very low power consumption, fast processing speed, and accurate data.

Integrated, highly accurate temperature and humidity sensors for more reliable simultaneous detection.

【Audible and Visual Alarm】: Real-time monitoring of CO concentration. In case of high concentration, an audible and visual alarm is triggered. Color changes according to the CO level:

0–25 PPM: flashing green block

25–50 PPM: flashing yellow block

50–100 PPM: flashing orange block

100–200 PPM: flashing red block

≥200 PPM: all four blocks flash

The buzzer emits a different number of beeps depending on whether the concentration reaches 25, 50, or 100 PPM.

【Multiple Applications】: Built-in high-capacity 1200mAh lithium polymer battery, Type-C charging port, long battery life. Suitable for various complex environments: homes, greenhouses, camping barbecues, factories, cars, environmental monitoring, etc.
