Data Loggers Products
The Em50 is a 5-channel, self-contained data recorder designed for use with any ECH 2O sensor. The sensors are plugged into the 5 channels and measured as directed by the user. Housed in a weatherproof enclosure with an O-ring seal, the Em50 is ideal for long-term outdoor use. With minimal battery usage, the Em50 can take readings as often as once per minute for over a year. Any combination of the listed sensors can be used.
The Em50 can be used with ECHO Utility software which allows you to configure and program your loggers, download data, scan the ports and save data directly in MS Excel format. The Em50 is compatible with any ECH2O sensor.
The Em5 Logger system is a low-cost, small, battery-operated 5-channel analogue logger system. The Em5b system is offered with the sensors listed below in any combination, up to a total of five sensors. The Em5b operates on 4xAAA batteries for up to six months and can store approximately 3400 readings. The Em5b can be used with the ECHO Utility software to set logging interval, sensor type and download data directly to MS Excel. The Em5b is compatible with EC-5, -10, and -20 sensors as well as the rain gauge and ECT temperature sensor.

EC–5 Soil Moisture Sensor
High-frequency operation (70 MHz) makes the EC–5 ideal for any soil type, including soils with varying degrees of EC (up to 8 dS/m). Its typical accuracy in any soil is ±3% without calibration and 1–2% with soil-specific calibration.
Supplied with 5m cable with 3.5mm jack plug.

Specification Sheet
10HS Soil Moisture Sensor
The 10HS Soil Moisture Sensor obtains volumetric water content by measuring the dielectric constant of the media through the utilization of capacitance/frequency domain technology. In addition, the 10HS sensors incorporate a high frequency oscillation, which allows the sensor to accurately measure soil moisture in any soil or soilless media with minimal salinity and textural effects.
Supplied with 5m cable with 3.5mm jack plug.

EC–TM Soil Moisture and Temperature Sensor
The EC–TM sensor incorporates a temperature reading into the traditional soil moisture sensor. Therefore, more data logger ports may 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 temperature is measured using an onboard thermistor. The EC-TM 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.
Supplied with 5m cable with 3.5mm jack plug.

Aquasorp Isotherm Generator
Aquasorp is an affordable isotherm generator. A moisture sorption isotherm maps the complex, product-specific relationship between water content and water activity and is the key to understanding and controlling product formulation, product stability, moisture sensitivity, temperature effects, and drying characteristics. The Dynamic Dewpoint Isotherm (DDI) method gives full sorption isotherm curve development (hundreds more data points in days instead of weeks). An easy to use software program simplifies data collection and analysis, including BET and GAB determination.

Operation Manual
MPS-1
Soil water potential is a key parameter for determining water availability for plant growth, water flow, and soil stability. Although an in-situ measurement of soil water potential has been the focus of considerable research over the years, existing solutions still have many drawbacks such as high maintenance, limited lifetime, individual calibration requirements, high cost, and small measurement range. The MPS-1 is a sensor that can be used in the field to accurately measure in-situ soil water potential without these limitations.

Soil Thermal Products
The KD2 Pro uses 3 thermal properties sensors to measure thermal diffusivity, specific heat, thermal conductivity and thermal resistivity. The KD2 Pro allows the user to choose an automated mode where the reading is displayed directly or a manual mode where you can download the raw values from each reading for further analysis using a spreadsheet program as required by IEEE and ASTM standards.

Additional Notes
Leaf Porometer SC-1
The SC-1 Leaf Porometer automatically measures stomatal conductance and eliminates human error by picking the end point. The direct readout displays data in terms of either conductance or resistance. The data can then be saved and downloaded to your PC via an included RS232 cable and download utility software.
