Campbell CS625 & CS616

    • High accuracy and high precision
    • Fast response time
    • Designed for long-term unattended water content monitoring
    • Probe rods can be inserted from the surface or buried at any orientation to the surface

    • Output
    CS625: 0 to 3.3 V square wave with frequency dependent on water content. CS616: ±0.7 volt square wave with frequency dependent on water content
    • Power
    65 milliamps @ 12 Vdc when enabled, 45 microamps quiescent typical
    • Measurement Time
    0.50 milliseconds typical
    • Enable Voltage
    4 Vdc minimum, 18 Vdc maximum
    • Maximum cable
    1000 feet (305 m)
    • Electromagnetic Compatibility
    The CS616/CS625 is OE compliant with performance criteria available upon request. RF emissions are below EN55022 limits if the CS616/CS625 is enabled less than 0.6 ms and measurements are made at a 1 Hz (1 per second) or slower frequency. The CS616/CS625 meets EN61326 requirements for protection against electrostatic discharge and surge.
    • Dimensions
    • Rods:
    300 mm (11.8”) long, 3.2 mm (0.13”) diameter, 32 mm (1.3”) spacing
    • Probe Head:
    85 mm x 63 mm x 18 mm (3.3” x 2.5” x 0.7”)
    • Weight Probe (without cable):
    280g (9.9 oz), Cable: 35 g m-1 (0.38 ozft-1)
    • Probe-to-Probe Variability:
    ±0.5% VWC in dry soil, ±1.5% VWC in typical saturated soil
    • Resolution:
    better than 0.1% volumetric water content
    • Water Content Accuracy:
    ±2.5% VWC using standard calibration with bulk electrical conductivity ≤0.5 deciSiemen meter-1 (dS m-1) and bulk density ≤1.55 g cm-3 in measurement range 0% VWC to 50% VWC
    • Precision:
    better than 0.1% volumetric water content
