| Sapflow Sensors | ||
|---|---|---|
| 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. |  |
|
| The Heat Field Deformation (HFD) technique is ideally suited to sapflow research projects that require the measurement of extended radial sapflow profiles to accurately map hydraulic architecture of trees. Similar to the HRM sap flow sensor the HFD sensor can measure high sapflow rates as well as low to zero and reverse sapflow. Hence as both sensors can measure in the same range the HFD sensor provides an extension of the HRM method making both sensors highly complimentary to each other in most sapflow measurement applications. |  |

| Rain Gauges & Pluviometers | ||
| Rainfall Station | The Rainfall Station is the latest innovation for total rainfall solution. The unit consists of a Tipping Bucket Rain Gauge mounted on a 2" BSP pipe and a stainless steel enclosure that encloses a data logger, a GSM modem and a 12VDC battery. |  |
| ML1 Event Logger | The ML1 is a one channel data logger specifically designed for recording rain fall events from tipping bucket rain gauges. Very low power consumption and a robust aluminium waterproof housing allow this logger to be deployed in the field for up to ten years in remote locations. |  |
| Research Rain Gauges | The design of these rain gauges includes several features to maintain accuracy of measurement. The recording and tipping cycle continues with rainfall while fine stainless-steel mesh prevents debris such as dirt and insects from entering the workings of the rain gauge. Other features to ensure maintained accuracy include a level bubble adhered to the base. |
