Negative oxygen ion monitoring instrument for scenic spotsProduct Introduction

UDH-ION-1 is a set of atmospheric negative ion monitoring instruments independently developed by Lanju Intelligent, which meets the prevailing technical specifications and has improved various technical indicators. The product adopts a unique collection tube capacitor and a pure imported signal processing unit, with high ion charge conversion efficiency and stable charge collection. It has the characteristics of strong anti-interference ability, strong rainproof ability, stable communication, high testing accuracy, strong environmental adaptability, and the ability to work continuously in the field for a long time.

UDH-ION-1 is equipped with a data receiving and analysis system. After the system is installed, any computer within the local area network can view the data and provide curve analysis, which can intuitively reflect ion changes. It has good dehumidification and dust prevention effects, and is equipped with anti condensation and icing devices inside, so that the equipment will not freeze or condense under various climatic conditions.

UDH-ION-1 adopts the "Gerdien Tube" air collector, a unique active suction collection tube capacitor, stable airflow, advanced negative pressure dust removal structure, and can operate in harsh environments for a long time. Calculate air negative ions using capacitive inhalation method. Air passes through the collection tube at a constant wind speed, and a negative voltage is applied to the pressure plate to attract positive ions. Correspondingly, the collection plate attracts negative ions. After passing through a charge amplifier, the voltage is converted from analog to digital, and finally the measured value is output.
