HD3910.2 Soil Moisture Sensor

HD3910.2 Soil Moisture Sensor

Features:

·Advanced measurement selection

HD3910.2: Equipped with a three electrode system, optimized for precise measurement of confined volumes (such as potted soil).

·Comprehensive measurement capability

Synchronize measurement of soil volumetric moisture content and temperature parameters.

·Reliability and Durability

The probe is pre calibrated at the factory and does not require on-site calibration. The sturdy plastic shell sealed with epoxy resin can maintain stable performance even under harsh working conditions.

The IP67 protection level ensures durability in harsh environments. The minimum invasive design ensures that the installation process does not affect the measurement environment.

·Installation convenience

Standard fixed cable (5 meters or 10 meters standard length), with an open core terminal for quick and easy installation.
