HD-SN1
This detector is equipped with an LCD screen that displays the concentration of negative oxygen ions in the air in real-time. The device adopts the standard ModBus-RTU communication protocol with RS485 signal output, achieving a maximum communication distance of 2000 meters (tested). The concentration of negative ions in the air is one of the indicators of air quality. The World Health Organization has also established relevant standards for the concentration of negative ions in fresh air. This detector can monitor air negative oxygen ions for forestry, environmental protection, meteorology, tourism sectors, and other units, contributing to improved air quality in both rural and urban areas, which holds significant importance for human society.

  1. Large LCD screen, aesthetically pleasing and elegant.

  2. Equipped with a dedicated 485 circuit and standard ModBus-RTU communication protocol, with configurable communication address and baud rate.
