The Fluid Loss Test Assembly provides a reliable means of determining the fluid loss characteristics of an oil well cement. Fluid Loss Testers measure fluid loss of cement slurries, drilling fluids, and fracturing fluids under elevated pressure and temperature conditions.

Fann Static Fluid Loss Testers come in Single Cell and Dual Cell models.

Fluid Loss Cells are fitted with a 325 mesh screen [3.5 in² (22.6 cm²) filtration area] backed by a 60 mesh screen. The 60 mesh screen provides a flow path for the cement filtrate as outlined in API Recommended Practice 10B. Cells are provided with openings on both ends with caps (double ended) for ease of maintenance.
