Tensiometers manufactured by Irrometer® meet highest expectations and have been continously optimized for more than 50 years. The Irrometer Tensiometers of the new generation are equipped with a new waterproof stainless steel manometer with improved pressure compensation, and read conveniently from top. The shaft offers an integrated water reservoir for easy replacement of lost water in field. The ceramic tip is exchangeable. The Tensiometer is filled air-free with water, and reacts extra fast to changes in soil water potential. Recommended accessory: Irrometer Service Pump.

The Watermark Sensor is a robust, user-friendly sensor, maintenance free, frost proof and buffered against varying salt contents of soil solution. The cable can be spliced up to a total length of 100m. However its reaction time to soil moisture variations is somewhat slower than tensiometer or volumetric sensors. Interpretation of data is easy, since measurement result is given in Centibar (soil water potential), valid for all soil types.

Sensor model EC-5 offers properties ideal for use in soilless substrates, growbags and pots: Cable extension up to 50 m possible.

TX-E is an electronic TX Tensiometer for data-logging, offering a linear Voltage Signal 0 to 5V DC. Therefore TX-E can be used with every Data logger, which can read a Voltage Signal. The TX-E is available with and without additional analogue gauge. Measurement range is 0 to 1000 hPa soil water potential. Apart from this offers the model TX-E all field approved properties of the analogue TX Tensiometers, such as extremely fast reaction on changes in soil water potential and very low maintenance requirements.

The DD-S is designed specifically for agricultural plants, small trees and branches. It is suitable for plants with a diameter of less than 5 cm. Due to a patented mounting method, the dendrometer also provides stable readings for very small plants.

Handmeter with integrated Sensor for PAR Radiation. Source of light, electric or sunlight, can be chosen for optimal accuracy. Measurement Range 0 - 2000 μmol/s*m2, Measures wavelenth between 400 and 700 nm. LCD Display.
