01AP4 Porometer
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

02SS1 SunScan Canopy Analysis System
The SunScan plant canopy analyzer system uses field measurements of Photosynthetically Active Radiation (PAR) in crop canopies to provide valuable information about Leaf Area Index (LAI) and biomass production.
- 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

08HH2 Moisture Meter
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

09SM150T Soil Moisture Sensor
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
Technical specifications
| NB | When used in portable mode the SM150T Sensor does not provide temperature indication. |
|---|---|
| Full range | 0 to 1.0 m3.m-3 |
| Temperature range Full accuracy over | 0 to 40°C |
