Weather Stations

Automatic weather stations from Delta-T can be as simple or as complex as your application requires. Even after installation, itís easy to expand or adapt the system;

Chlorophyll Meter

The CCM200 Plus Chlorophyll Meter accurately determines chlorophyll content in plants and crops.

Sap Flow Systems

The newest method of transpiration measurement is now available from Dynamax for large trees and plants. The Thermal Dissipation Probe (TDP) transpiration sensor measures sap

High Pressure Flow Meter
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. You can quickly measure the major components of the hydraulic conductance in the soil-plant-atmosphere continuum (Tyree, 1994) The HPFM will help plant physiologists and agronomists look forward to those seasonal studies of root and shoot progression, water potential, or soil treatment effects.
