1. Product Introduction

The JDZ02 (05)-1 rainfall sensor is a hydrological and meteorological instrument used to measure natural rainfall. It converts rainfall into digital information output in the form of switch signals to meet the needs of information transmission, processing, recording, and display.

When paired with recording or display components, this instrument enables wired rainfall data transmission, display, and automatic recording. When integrated with a wireless hydrological automatic monitoring system, it serves as a dedicated sensor for remote rainfall measurement and flood reporting.

2. Product Features

The tipping bucket component of this instrument features a finely crafted support system with low frictional torque, ensuring sensitive tipping, stable performance, and reliable operation. The rain-receiving orifice is made of stainless steel through integrated stamping and drawing, providing a high smoothness finish and minimizing errors caused by water retention. The instrument housing is constructed of stainless steel, offering strong rust resistance and excellent appearance quality.
