| Sapflow Sensors |
Heat Ratio Method (HRM)
HRM Installation Kit |
The Heat Ratio Method (HRM) is a modification of the Compensation Heat Pulse Method (CHPM). The HRM improves on the CHPM by allowing very slow flow rates and even reverse sap flow to be measured. This allows water flows to be monitored in stems and roots of a wide range of different species, sizes and environmental conditions, including drought. |
 |
| Energy or Heat Balance (Dynagage) |
The stem heat balance (SHB) method was originally proposed by Sakuratani (1981) to measure the mass flux rate or sapflow in small stemmed herbaceous plants.
The SHB method is based on the energy balance of a stem segment to which regulated heat energy is constantly supplied by an external annular heater. |
 |
| Thermal Dissipation (TDP) |
The Thermal Dissipation Probe (TDP) directly measures sap velocity which can be converted to volumetric flow rate given an accurate measurement of sapwood area for the tree. TDP is an uncomplicated and inexpensive method ideally suited to whole plant transpiration measurements on large diameter trees. |
 |
| Dendrometers |
| Electronic Dendrometers for the real time measurement and logging of fruit & stem growth |
| Manual Band Dendrometer DB20 (NEW) |
Manual Band Dendrometers or increment gauges are used extensively in commercial forestry and forest research. They are a very reliable and low cost method of accurately measuring and monitoring tree growth rates. |
 |
| Logging Band Dendrometer DRL26 (NEW) |
Whole tree water relations research has just become easier and more accurate. The logging band Dendrometer now incorporates its own self-contained datalogger. Using an internal lithium battery there is no need for external batteries or solar panels to power the logger, meaning it can be attached to a tree and set logging with no other accessories or requirements. |
 |
| DEX Dendrometers |
The DEX20, DEX70, DEX100 and DEX200 are highly precise electronic dendrometers that measure the growth and size of plant stems and fruits. The DEX is a caliper-style device with a full bridge strain gauge attached to a flexible arm. The output signal is then recorded by a datalogger or computer in real time. |
 |
| Porometers |
| Leaf Porometer |
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. |
|

| HPFM-C |
The High Pressure Flow Meter (HPFM) is designed to perform quantitative root and stem analysis without having to dig up roots or drag limbs back to the lab. In most cases, the analysis of a sample root or shoot is completed in as little as 10 minutes. |
|
| HCFM-XP |
The Hydraulic Conductance Flow Meter (HCFM-XP) is designed to perform quantitative root and stem analysis without having to dig up roots or drag limbs back to the lab. In most cases, the analysis of a sample root or shoot is completed in as little as 10 minutes. |

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 |
ICT International's LW2 and LWH leaf wetness sensors replicates the effect of moisture on leaf or artificial surfaces and can be used for a variety of situations such as leaf wetness, rain event or other applications where over-spray events need to be monitored or controlled. |
