Edaphic Scientific specialises in technology for the measurement of water potential of materials. The MPS-6 sensor is ideal for researchers, growers and students because it is calibrated, digital, easy to install, and requires virtually no maintenance. The MPS-6 replaces old technology such as tensiometers and gypsum blocks. The WP4C instrument is ideal for researchers and engineers for soil water characteristic curves. But the WP4C can measure the water potential of any material including seeds, leaves and food! Edaphic Scientific also offers field installation and remote download of data over the internet.
