Round Bottom Ceramic Cups
Soilmoisture Equipment manufacture a range of Round Bottom Ceramic Cups with necks suitable for connecting to tensiometers and other similar equipment for the measurement of soil water potential.
The Round Bottom Cup with Tapered Neck Top is available in one size, but in four different pressure and flow castings:
- 1/2 Bar Standard Flow
- 1 Bar Standard Flow
- 1 Bar High Flow
- 2 Bar High Flow
The Round Bottom Cup with Neck Top is available in three outside diameters and different flow castings, suitable for applications in research and development:
- 48.26 mm (1.471″) Outside Diameter
- 1 Bar Standard Flow
- 1 Bar High Flow
- 2 Bar Standard Flow
- 3 Bar Standard Flow
- 5 Bar Standard Flow
- 9.525 mm (1.900″) Outside Diameter
- 1/2 Bar Standard Flow
- 1 Bar Standard Flow
- 1 Bar High Flow
- 54.102 mm (2.375″) Outside Diameter
- 1 Bar High Flow
