Commercial-grade Data Logger System Em50

The Em50 is a 5-channel, self-contained data recorder designed for use with any ECH₂O 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. Available as a free download for Windows - click here to download ECHO Utility (1.3MB installer file)

Available sensors for EM50 Logger System
EC-20 Soil Moisture Probe	The EC-10 and EC-20 are designed for medium-textured soil types with low EC conditions. Their typical accuracy in these soil types is ±4% without calibration and 1-2% with soil-specific calibration. Suppied with 5m cable with 3.5mm jack plug.
10HS Soil Moisture Sensors	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.
EC-5	High-frequency operation (70 MHz) makes the EC-5 ideal for any soil type, including soils with varying degrees of EC (up to 8dS/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.
5TE Sensors	The 5TE is designed to measure the water content, electrical conductivity, and temperature of soil and growing media. Supplied with 5m cable with 3.5mm jack plug.
MPS-1 NEW	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.
ECRN-100	Double-spoon tipping bucket rain gauge with 0.25mm tip and resolution. Durable UV and water resistant ABS. Level bubble. 170mm x 142mm
ECT Air and Soil Temperature Probe	The Temperature Sensor can measure both air temperature and soil temperature. It connects to any channel in a Decagon Datalogger for long-term temperature monitoring. Supplied with 3m cable with 3.5mm jack plug.
PASSECT	Passive Radiation Shield with preinstalled ECT sensor The Radiation Shield is HIGHLY RECOMMENDED to protect the Temperature Sensor and the RH/Temp Sensor from ambient interference. Without proper protection, these sensitive devices can give inaccurate readings.
PYR	The pyranometer measures the solar radiation flux density (in watts per metre square) from a field of view of 180 degrees. This pyranometer is completely water proof, submersible, and designed for continuous outdoor use. Supplied with with level plate, 3m cable, 3.5mm jack plug.
PAR	The PAR Photon Flux sensor measures the Photosynthetic Photon Flux (PPF) in μmol m-2 s-1. from a field of view of 180 degrees. It is completely water proof, submersible, and designed for continuous outdoor use. Supplied with with level plate, 3m cable, 3.5mm jack plug.
Leaf Wetness Sensor LWS Brochure (140K PDF)	The Dielectric Leaf Wetness Sensor (LWS) enables accurate and affordable leaf wetness monitoring. The Leaf Wetness Sensor determines the presence and duration of wetness on a leaf’s surface, enabling researchers and producers to forecast disease and protect plant canopies. Leaf Wetness Sensor, 5m cable, 3.5mm jack plug.
RHT	RH/Temperature sensor measures relative humidity (RH) and temperature, making it ideal for use with ECH₂O probes in studying microclimate and evapotranspiration. Supplied with 3m cable with 3.5mm jack plug.
PASSRHT	Passive radiation shield with preinstalled RHT sensor. The Radiation Shield is HIGHLY RECOMMENDED to protect the Temperature Sensor and the RH/Temp Sensor from ambient interference. Without proper protection, these sensitive devices can give inaccurate readings.
