Manage water responsibly and reduce operating expenses. The TDR 100 is the ideal tool for quick, reliable, and convenient measurement. Whether you're in a field, greenhouse, or laboratory, the TDR 100 will provide the results you want.
Based on the proven time-domain measurement technology, the portable TDR 100 accurately measures soil moisture across the full range of soil moisture conditions. Select from the 1.5in, 3in, 4.8in, or 8 in (3.8cm, 7.5cm, 12cm or 20cm) probe rods to suit your measurement depth. The LCD interface provides two modes: volumetric water content and relative water content (irrigation management) mode.
Hand-held design allows for easy transporation and storage. Units connected by 5ft. Cable. Measures in less than one second. This meter has no data logging or geo-referencing capability. For those features, please take a look at our FieldScout TDR 300 Soil Moisture Meter.
