2.Technical specifications
2.1the sensor principle: gold-plated polarized parallel electrodes
2.2test object: the air of positive and negative ions
2.3air velocity: design to 600 cm3/sec, 75% design can be gleaned from the ions in the air. Note When the battery is low, fan speed will be reduced, actual measurements, when you faster than the default 80cm/sec, collected ions will be higher than 75% and vice versa when the speed is lower than 60cm/sec, and collected ions can 75%. Recommended for everyday use AC power supply, to provide more stable power supply.
