SWM 5000 Soil Moisture Meter

The SWM 5000 is a high-precision handheld soil moisture and temperature measurement system designed for both field and laboratory use. Based on the advanced FDR (Frequency Domain Reflectometry) technology, it delivers rapid, reliable measurements of volumetric soil moisture content while simultaneously measuring soil temperature via an internal NTC sensor.
Equipped with a robust stainless-steel probe (available in lengths up to 1 000 mm / Ø 20 mm) for manual or hydraulic insertion, the SWM 5000 allows deep-layer profiling of soil moisture—ideal for irrigation management, precision agriculture, soil research and environmental monitoring.
Smart-integration is provided through the ‘SWM Companion’ smartphone app (Android/iOS) enabling wireless Bluetooth 4.2 data transfer, field data logging, measurement scheduling and GPS-tagged field mapping.
Whether used for stand-alone handheld probing or mounted measurement systems in agricultural vehicles, the SWM 5000 helps you optimise water use, better understand soil moisture dynamics and enhance yield potential.

Key Features / Highlights

• • Built-in FDR technology for volumetric moisture measurement: accurate and minimally influenced by soil salinity or texture.
• • Soil temperature measurement via internal NTC sensor.
• • Stainless-steel probe (up to 1 m length, Ø 20 mm) with 100 mm insertion-depth markings for manual or hydraulic insertion.
• • Handheld main unit: 83 × 180 × 55 mm, weight approx. 330 g (basic unit) for ease of field use.
• • Splash-proof housing (IP 40), rugged for field conditions.
• • Fast measurement time: ~2 seconds for both moisture & temperature.
• • Data logging capacity (~3 440 measured values) with adjustable measuring cycle (1 min to 24 h).
• • Wireless Bluetooth connectivity and mobile-app support for smarter field workflows.

Technical Specification

Application /Usage Areas

• • Precision agriculture & irrigation: Monitoring soil moisture to optimise water use, avoid over-/under-watering and maximise crop yield.
• • Soil science research: Profiling volumetric water content at different depths to study infiltration, percolation and root-zone behaviour.
• • Environmental & hydrology studies: Monitoring soil moisture–temperature relationships in field studies, watershed hydrology and climate research.
• • Agronomy and field trials: Data logging and GPS-tagged measurements ideal for mapping soil moisture variability across fields or experimental plots.
• • Irrigation system calibration & validation: Use as reference measurement tool for validating automated irrigation systems or sensor networks.

User Benifts

• • Rapid, reliable soil moisture and temperature data in a single instrument: reduces equipment requirement and field time.
• • High portability and rugged design: field-usable, minimal logistical burden.
• • Wireless app-integration with data-logging simplifies field workflows, data export and advanced mapping.
• • Deep-probe options allow sensing at relevant depths where plant roots access water – yields more actionable data compared to surface-only sensors.
• • Helps optimise resource usage (water, nutrients) and supports sustainability goals in agriculture.

Considerations / Best Practice

• • For best accuracy, ensure the probe insertion is consistent (depth, soil contact) and avoid large air gaps around the probe tip – soil structure affects results.
• • Calibration may be required if the soil type is extremely unusual (very high clay, organic matter content); although the FDR method used minimises many soil-type influences.
• • The unit’s operating temperature is 0 °C to +40 °C for the main body – for cold field work, verify battery performance and unit stability.
• • While the probe body is stainless steel and robust, handle the sensor tip and cable connectors with care to maintain long-term reliability.
• • The logged data should be periodically downloaded via the app and backed up; battery status should be monitored to avoid data loss during field campaigns.
