Portable Ozone Analyzer Multifunctional Intelligent O3 Ozone Meter Gas Detector Sensor Quality Poll

Temperature and humidity technical indicators. When low battery icon is displayed, the device needs to be charged. Insert the included or another compatible -USB charging cable into the device. Attach the other end to a USB DC charger (such as a smart phone charger) that outputs DC 5V at Greater than =1000mA. Fully charge for at least 2-3 hours before use. Avoid charging with a USB computer port which only outputs 500mA.
