	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.
	AccuPAR LP-80 The new AccuPAR model LP-80 is Decagon's newest generation of ceptometer, designed for quick and reliable measurement of PAR and LAI in plant canopies. With the new LP-80, you get instant real-time PAR measurements as soon as you turn it on, and your LAI data is updated with each PAR measurement.
	ECH₂O EC-20 ECH₂O is a capacitance probe that measures dielectric permittivity of the surrounding medium. In soil, dielectric permittivity is directly related to the water content. The ECH₂O probe outputs a voltage proportional to the dielectric permittivity, and therefore the water content of the soil.
	WP-4 Dewpoint Potential Meter The WP4 and WP4-T give water potential readings directly in Megapascals within 5 minutes. It directly measures water potential from 0 to -60 MPa with excellent accuracy. The instrument is easy to use and maintain, and calibration is simple.
	KD-2 and KD-2 Pro The KD2 and KD2 Pro uses 3 thermal properties sensors to measure thermal diffusivity, specific heat, thermal conductivity and thermal resistivity.
	ProCheck Decagon’s ProCheck instantaneously displays calibrated readings of any Decagon soil moisture or environmental sensor.
	Mini-disk Infiltrometer Decagon's handheld Mini-disk Infiltrometers provide quick and convenient measurement of soil hydraulic conductivity. The infiltrometer is constructed of a polycarbonate tube with a semi-permeable stainless steel sintered disk. An adjustable steel tube is installed above the sample chamber to regulate the suction rate.
	Drain Gauge (Gee passive capillary Lysimeter) Chemical leaching is a growing concern to scientists, farmers, golf-course and waste site operators. The Gee deep drainage monitor provides an affordable and accurate solution to this problem. The Gee passive capillary lysimeter (Drain Gauge) is much smaller than comparable instruments, and its cost allows for more measurement sites over a large range of locations for the monitoring of deep drainage.

Soil Moisture Products
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	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.

Temperature Measurement

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.

Relative Humidity

RHT
Relative humidity and temperature sensor

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.

Leaf Wetness Sensors
Leaf Wetness Sensor Used with the Em50 logger system 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.
