Ultra HPHT filter press named HTD17375 is a professional instrument, used to measuring the filtration amount of drilling fluid and cement slurry under simulative deep well conditions (Ultra high temperature and high pressure), and also make filter cake after filtering under the same conditions. The filter is mainly composed of main body, drilling fluid cup, high pressure filtrate receiver，control box and pipeline system, etc.

Our filter design and produce base on American petroleum institute (API) standard, it has the characteristic of high temperature control precision, good repeatability, small error, simple operation, accurate measurement and etc, has widely used in oil fields, scientific research institutes, laboratories and other departments.

Pour the quantitative drilling fluid samples into the drilling fluid cup. After sealing, put the drilling fluid cup into the heater and heat it. At the same time, inflated and pressurized the drilling fluid cup quantitatively through the pressurizing pipe. Under some kind of temperature and pressure conditions, pressurize the sample to produce the filtrate pass through the filter screen or filer paper in the drilling fluid cup, and then evaluate the filtration performance of drilling fluid by measuring the volume of filtrate.
