Mini-Disk Infiltrometer Decagon's handheld Mini-disk Infiltrometer measures soil hydraulic conductivity quickly and easily in any soil type. The infiltrometer is constructed of a polycarbonate tube with a semi-permeable stainless steel sintered disk on the bottom. An adjustable steel tube above the sample chamber regulates the discharge rate. |

Model: WP4 & WP4-T Dewpoint Meters Measuring water potential using a pressure plate or filter paper is imprecise and can take several weeks. The WP4 and WP4-T measure water potential in less than 5 minutes from 0 to -300 MPa with a resolution of 0.1 MPa. Using the AOAC-approved Chilled Mirror Dewpoint Technique, the WP4 measures water potential by determining the relative humidity of the air above the sample in a closed chamber (at temperature equilibrium, relative humidity is a direct measurement of water potential). The instrument is easy to use and maintain, and calibration is simple. |

Model: Soil Moisture, Soil Temperature & Electrical Conductivity(EC) Sensor, ECH2 The ECH2O-TE sensor measures soil moisture, soil temperature, and bulk electrical conductivity (EC), three fundamental measurements needed for a variety of plant studies. Three measurements are taken in one sensor allowing more data logger ports to be used for additional environmental measurements. Volumetric water content is obtained by measuring the dielectric constant of the media through the utilization of capacitance/frequency domain technology while EC is obtained using a Wenner array. The ECH2O-TE sensor incorporates the same high frequency oscillation as the EC-5, which allows the sensor to accurately measure soil moisture in any soil or soilless media with minimal salinity and textural effects. Applications include plant sprouting and growth studies, plant mortality prevention, and greenhouse monitoring. |
