Product overview
The CHCNAV H960 is a 16-channel automated data logger for long-term, unattended geotechnical and environmental monitoring. It accepts vibrating wire, differential resistance, current, voltage, digital and switch inputs and is built for direct outdoor installation with IP67 protection and full interface lightning surge protection.

Main features

• Sensor compatibility: vibrating wire, differential resistance, current, voltage, digital and switch signals.
• Rugged enclosure: IP67-rated housing and full lightning surge protection on all interfaces.
• Integrated design: multi-power inputs, built-in high-capacity battery and direct solar input support.
• Dual data transmission: integrated 4G and RJ45 Ethernet with automatic breakpoint resume.
• Ultra-low power: ≤0.3 W standby, ≤1 W during acquisition; designed for extended operation (~15 days) in low-sunlight configurations.
• Local storage: 32 MB internal memory (stores >1.5 million records) for data integrity during transmission interruptions.

Benefits and performance

• Versatile integration: supports a wide range of geotechnical and environmental sensors for soil, water and structural monitoring.
• Reliable field operation: IP67 and interface surge protection permit direct outdoor deployment without additional cabinets.
• Resilient communications: dual-mode transmission and automatic resume ensure data continuity on unstable networks.
• Extended autonomy: low power consumption combined with integrated battery and solar input reduces maintenance visits.
• On-device data protection: local memory safeguards data history during network outages.

Compatible sensor suite (examples)

• HC-RD508 Radar Water Level Meter — pulse radar for liquid level monitoring.
• HC-RAIN-1 Rain Gauge — stainless-steel tipping-bucket with pulse output.
• HC-CA-2.0 Fixed Inclinometer — three-axis inclinometer for continuous 3D measurements.
• HC-QJ-1 Tiltmeter — high-precision digital tilt sensor for structural monitoring.
• HC-SA-3.0 Vibrating Wire Piezometer — long-term pore-water pressure measurement.
