• Advanced Optical Sensing Technology Utilizes precision-engineered drop sensing mechanism to measure individual raindrops. The optical sensor counts each droplet passing through the specially designed chamber, converting it into accurate rainfall data. This method provides more reliable measurements than traditional tipping bucket designs.
• Compact & Lightweight Construction The streamlined plastic housing measures just 6.3×4.7 inches and weighs under 1.5 lbs for easy installation. Mounts securely on poles, roofs or other outdoor locations without requiring heavy support structures. The neutral color scheme blends discreetly into various environments.
• Maintenance-Friendly Design Features a removable rain collection cone for simple cleaning and maintenance. The optical components are sealed to prevent dust and debris interference. All wear-resistive materials ensure long-term performance with minimal upkeep requirements.
• Laboratory-Tested Accuracy Delivers ±4% measurement precision in controlled testing at 2mm/min rainfall intensity. The consistent performance provides reliable data for critical applications requiring exact precipitation measurements. Regular calibration ensures maintained accuracy over time.
• Multi-Industry Applications Ideal for agricultural irrigation systems, marine navigation weather stations, and environmental monitoring networks. The RS485 output integrates seamlessly with most industrial control systems and IoT platforms. Suitable for both permanent installations and temporary field studies.
