IMKO Pico soil moisture sensor

The IMKO PICO series of soil moisture sensors provides fast, accurate measurement of volumetric water content, temperature, and electrical conductivity for environmental monitoring, agriculture, geotechnical engineering, and research applications. Using IMKO's proven TRIME® Time Domain Reflectometry (TDR) technology, PICO sensors deliver highly reliable measurements with minimal calibration requirements across a wide range of soil types.

Designed for long-term installation or portable field use, the PICO range includes sensors for near-surface monitoring, soil profiling, greenhouse applications, weather stations, infrastructure monitoring, and scientific research.

Accurate Soil Moisture Monitoring

PICO sensors utilise guided radar (TDR) technology to measure soil moisture with high precision while remaining largely unaffected by soil texture, mineral content, or electrical conductivity. The large measurement volume provides representative readings, even in heterogeneous soils, reducing the need for site-specific calibration.

Depending on the model, sensors can measure:

• Volumetric soil moisture

• Soil temperature

• Electrical conductivity (EC)

Flexible Solutions for Every Application

The PICO range includes several sensor configurations to suit different monitoring requirements:

• PICO32 – Compact sensor for near-surface monitoring, turf, greenhouse and laboratory applications.

• PICO64 – Larger measurement volume for agricultural, environmental and infrastructure monitoring.

• PICO IPH2 – Portable profiling probe for moisture measurements at multiple depths.

• PICO Profile – Permanent installation system for continuous soil moisture profiling.
