Half-bar Ceramic (CF): High temperature fire, Alumina body, highly porous, high permeability, high flow rate, high mechanical strength, white color, inert surface area, very low ionic exchange capacity. Suitable for tension tables, soil water sampling under low tension (50 kPa and lower).

One Bar Ceramic (C1): Moderate temperature fire, largely Talc body, high porosity, good mechanical strength, ivory white, Suitable for low-range tensiometers, extraction plates, tension tables. Some ionic exchange capacity, not suitable for soil water samplers (chemical analysis of water samples).

One Bar High Flow Ceramic (C1H): High temperature fire, Alumina body, highly porous, high permeability, high flow rate, high mechanical strength, white color, inert surface area, very low ionic exchange capacity. Suitable for extraction plates, tension tables, soil water samplers, and tensiometers.

 Two Bar Ceramic (C2): Moderate temperature fire, ball clay body, good porosity, good hydraulic conductivity, white color, suitable for extraction plates.

Two Bar High Flow Ceramic (C2H): High temperature fire, Silica body (porcelain), good porosity, good hydraulic conductivity, white color, very low ionic exchange capacity, inert surface area, suitable for soil water sampling.

Three Bar Ceramic (C3): Moderate temperature fire, ball clay body, good porosity, good infiltration rate, moderate mechanical strength, hard tannish-white color, suitable for extraction plates.

Custom-Made Ceramic Items:

Since SoilMoisture ceramics are unique in the world, the company manufactures 1000s of custom-made ceramic items for researchers and manufacturers worldwide each year.  

Please consider the following items when ordering a custom-made ceramic item.

+ Review Standard Options: Before asking for a custom-made ceramic item (which will be more costly compared to a similar standard item), review all our standard ceramic items to see if any of them works for your application.

+ Drawing: If needed, provide us with the drawing of the custom-made item. Drawing is not required for simple shapes like a round plate, a square plate, a cylinder, etc.

+ Dimensions: Make sure to include all the dimensions required to make the ceramic item.

+ Tolerances: This is a critical piece of information that many overlook and fail to provide. Please note that we will be unable to provide you with an item price or manufacture an item unless all the dimensions are provided with their associated tolerances. Our ‘regular’ tolerance is +/-0.020 inches. Tighter tolerances are more costly.

+ Ceramic type: SoilMoisture manufactures 8 types of porous ceramic (CF, C1, C1H, C2, C2H, C3, C5, and C15). You need to choose a ceramic type for your custom-made order. Please note that SoilMoisture does not provide other types of ceramics. In other words, we do not custom-make ceramic types.

+ Quantity: SoilMoisture does not usually offer a price break for quantities lower than 500 units. Nevertheless, the quantity is needed for generating an official price quote.
