10HS Soil Moisture Smart Sensor

Measures soil moisture over a large volume of soil; integrates the field-proven 10HS Sensor and a 12-bit A/D; ±3% accuracy in most soils conditions, ±2% accuracy with soil-specific calibration.

Measures soil moisture over a large volume of soil. This sensor integrates the field-proven 10HS Sensor and a 12-bit A/D, providing ±3% accuracy in most soils conditions, and ±2% accuracy with soil-specific calibration. The 10cm probes measure soil moisture over a larger volume of soil, helping to average out any soil variability. Readings are provided directly in volumetric water content. The sensor’s high-frequency design minimizes salinity and textural effects and gives it a wide measurement range.

Also available in a wireless model for use with the HOBOnet Field Monitoring System.

Specifications

Measurement range in soil:	0 to 0.570 m³/m³ (volumetric water content)
Accuracy:	±0.033 m³/m³ (±3.3%) typical 0 to +50°C (+32° to +122°F) for mineral soils up to 10 dS/m. ±0.020 m³/m³ (±2%) with soil specific calibration.
Resolution:	0.0008 m³/m³ (0.08%).
Soil probe dimensions:	160 x 32 x 2 mm (6.5 x 1.25 x 0.08 in.).
Weight:	190 grams (6.7 oz)
Decagon probe part no.:	10HS
Sensor operating temperature:	0° to +50°C (+32° to +122°F). Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F) and the smart sensor tube (the white portion of the sensor cable that houses the electronics) can be exposed to temperatures up to +70°C (+158°F), the soil moisture data collected at these extreme temperatures is outside of the sensor’s accurate measurement range. Extended temperatures above +50°C (+122°F) will decrease logger battery life when using for the S-SMD-M005 smart sensor.
Volume of influence:	1 liter (33.8 oz)
Sensor frequency:	70 MHz
Logging Rate:	12
Number of data channels:	1
Measurement averaging option:	No

Length of Smart Sensor network cable:	0.5 m (1.6 ft)
Battery Life:	– The CE Marking identifies this product as complying with all relevant directives in the European Union (EU)
Time Accuracy:	± 1 minute per month at 25°C (77°F)
Full Memory Dowload:	Approximately 45 seconds; may take longer the farther the device is from the logger
Wetted Materials:	Polypropylene case, EPDM O-ring
Dimensions:	3.35 x 5.64 x 1.6 cm (1.32 x 2.22 x 0.63 inches)
Weight:	12.75 g (.45 oz)
The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
