        This product is completely independently developed by Wanyi Technology Co., Ltd. and conforms to the international general technical specifications. All technical indicators have reached the international level. This product uses a cylindrical capacitance negative ion sensor ion acquisition unit and ultra-micro current signal processing unit. High ion charge conversion efficiency and stable charge collection. It has the characteristics of strong anti-interference ability, high test accuracy, wide measurement range, and strong environmental adaptability. This product has a 232 communication interface and adopts a standard Modbus communication protocol for easy data reading.
Cylinder capacitive anion sensor is a mature and complex anion sensor. It has a higher technical level than parallel plate sensor. At present, mid-to-high-end air ion detectors basically use this sensor structure. The overall structure of cylinder capacitive anion sensor It consists of three concentric cylinders. The outer cylinder and the inner cylinder shaft are electrodes. Constant voltage is applied. There is an exhaust fan behind the cylinder. When the fan starts, air is sucked in through the cylinder. When the positive and negative ions in the air flow through the cylinder, They will be adsorbed on cylinders of different polarities, and will generate discharge under the influence of the torque formed by the cylinder voltage. These discharge signals are recorded to calculate the number of positive and negative ions in the air.
