CS625 Water Content Reflectometer for CR200-series
The CS625 measures the volumetric water content from 0% to saturation. It is similar to our CS616 but is designed specifically for CR200(X) and CR300-series dataloggers. This reflectometer has a 0 to 3.3 V square wave frequency output that our CR300-series and CR200(X)-series dataloggers can measure.
Measurements Made | Volumetric water content of porous media (such as soil) |
---|---|
Water Content Accuracy | ±2.5% VWC (using standard calibration with bulk EC of ≤ 0.5 dS m-1, bulk density of ≤ 1.55 g cm-3, and measurement range of 0% to 50% VWC) |
Required Equipment | Measurement system |
Soil Suitability | Long rods and lower frequency are well-suited for soft soil with low electrical conductivity (< 2 dS/m). |
Rods | Not replaceable |
Sensors | Not interchangeable |
Operating Temperature Range | 0° to 70°C |
Probe-to-Probe Variability | ±0.5% VWC in dry soil, ±1.5% VWC in typical saturated soil |
