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 12cm or 20cm (4.8in or 8 in) 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 transportation and storage. Units connected by 5ft. Cable. Measures in less than one second.
Measurement rods must be purchased separately for Field Scout TDR products.
Track soil moisture, salts, and soil temperature: all with a single sensor!
Whether it’s container pots in a greenhouse or turf on a putting green, the salinity of the root zone is a critical element for healthy plant growth. Irrigation, fertilizers, and crop demand all impact salt concentrations. High levels can damage the plant: low levels can lead to nutrient deficiencies.
Identify situations where soil salinity is an issue or where certain moisture and temperature conditions facilitate soil-borne diseases
The key is knowing both when and how much to water!
Maintaining a healthy soil moisture and water balance is essential for producing high quality plants. Under-watered plants suffer from nutrient deficiencies, stunting and wilting. Conversely, over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle. Extreme over-watering will suffocate the plant and lead to root death.

Place a Watermark sensor in the root zone of your crop or turf and use the handheld Digital Meter for an instant reading or moisture from 0 (saturated) to 200 (dry) centibars.
The Watermark adapter makes these Watermark sensors compatible with our Watch Dog weather stations and data loggers.
