Features

• Accurate measurement: the international advanced coaxial double-cylinder capacitive suction method is adopted as the measurement method

• Small size: compact internal structure, exquisite appearance, can adapt to a variety of environmental detection, convenient for mobile use;

• Long standby: Built-in large-capacity lithium battery, not limited by power supply and venue, ready to test;

• Intuitive reading: 2.8-inch LCD display, real-time display of negative (oxygen) ions (maximum, minimum, average), temperature and humidity measurement results;

• Responsive: the data refresh frequency reaches 1 second/time;

•Simple operation: the instrument is simple and direct to operate, and the full-color large font display is clear and clear;

•Automatic statistics: automatically calculate the maximum, minimum, and average value within a time period.
