Stomatal aperture is the dominant factor in the diffusion conductance of leaf surfaces, which controls both the water loss from plant leaves and the uptake of CO2 for photosynthesis. Measurements of diffusion conductance are therefore important indicators of plant water status and provide a valuable insight into plant growth and plant adaptation to environmental variables.

• Product Resources
• Simple absolute calibration in the field
• Minimises leaf stress during measurement
• Award winning user interface
• 5 year warranty
• Sophisticated temperature compensation
• Unstirred leaf chamber minimises unwanted stomatal closure
• Lightweight ergonomic sensor head

• Product Resources
• Measures incident and transmitted PAR in canopies
• Direct display of Leaf Area Index (LAI)
• Usable in cloudy and clear conditions
• Ideal for phenotyping applications

No other soil moisture probe system enables you to monitor your soil water profiles with such ease and flexibility. Install an access tube into the soil, insert the PR2 Profile Probe and press the HH2 [Read] button to display an instantaneous reading, or connect the PR2 to a data logger (GP2 or DL6) and leave the system to record soil moisture changes over time.

• Product Resources
• Soil moisture content profiles down to 1m
• Dual purpose – installed and portable
• Uses access tubes for easy probe insertion and removal
• Highly reliable field-proven instrument
• Soil moisture content – not just trends
• Out of the box solution – supplied with calibrations for common soil types
• Portable meter option for multi-site measurement

With its 1% accuracy the ThetaProbe has set the standard for soil moisture measurement for more than 20 years.

• Product Resources
• Can be buried or used as portable probe
• Easy data logger connection (0 – 1 V DC)

المواصفات الفنية

When buried in soil or substrate the WET150 Sensor simultaneously measures three crucial variables that influence plant growth: moisture content, temperature, and electrical conductivity (EC) – a strong indicator of the general nutrient level.

• Product Resources
• Measures moisture, temperature and EC
• Digital SDI-12 for easy system integration
• Rugged, buriable and low power
• Accurate monitoring of growing conditions
• Detachable and extendable cable system
• 5 year warranty
• Use many sensors with just a single master device, reducing complexity and costs

The HH2 Moisture Meter is a versatile readout unit for use with Delta-T soil moisture sensors. It can be used with the PR2 Profile Probe (both analogue and SDI-12* versions), ML3 ThetaProbe, SM150T and WET Sensors.

• Product Resources
• Immediate display of water content
• Reads ML3, SM150T, PR2 (analogue and SDI-12) or WET Sensor
• Stores up to 1500 time-stamped readings
• How do I upload the WET sensor calibration file into the HH2 handheld reader unit?
• Disconnect the battery.
• Short out the battery connection terminals with a metal object, e.g. a screwdriver blade.
• Reconnect the battery: snap the connector in place in a single continuous action.

المواصفات الفنية

The SM150T measures soil moisture and temperature with research-grade accuracy. It offers stable, robust and reliable performance at a great price.

• Product Resources
• Built in temperature measurement
• Robust and buriable, with 5 year warranty
• Minimise compression of the soil. A soft container could mean you squash the sides and deform the soil, which then has an altered bulk density, resulting in the volumetric water content reading being changed.
• Minimise movement of the pins inside the container; this can disturb the media, creating air spaces around the pins

The EQ3 Equitensiometer uses class leading ThetaProbe technology to avoid the many problems of water-filled tensiometers. It measures water potential (matric potential) in the range 0 to -1000 kPa and provides an accurate loggable output. It is particularly well suited for use in dry soils.

• Product Resources
• Convenient, accurate and reliable alternative to water-filled tensiometers
• Excellent range 0 to -1000 kPa
• Maintenance free: no refilling, degassing, or topping up
• Built in temperature sensor
• Buriable and frost resistant (IP68)
