Pressurized Consistometer

Model #: M22-400


The CTE Model 22-400 is specifically designed to measure the thickening time of cement slurries in strict compliance with ISO-10426, API Spec 10A and API RP-10B Schedules. With high temperatures and pressures applied to the cement, it is possible to simulate a variety of conditions found in actual down-hole well cementing. The measured thickening time can then be used to formulate actual well cementing plans.

M22-400 Operation Manual


Operation of the pressurized consistometer is simple with all of the operational controls conveniently located on the front panel. The readout indictors for the viscosity, pressure, and temperature, as well as operational instructions, are easily read from the 12-inch color touch-screen. The consistometer is designed so that closure, heating, and pressurization can be achieved quickly. This ensures compliance with the requirement of ISO and API schedules. The temperature control system will automatically control the rate of temperature rise of the slurry (i.e. temperature gradient). When the slurry reaches the desired maximum temperature, the system will hold the slurry temperature at that level. The temperature and viscosity of the slurry, and current pressure are displayed constantly on the touch-screen numerically and graphically. Contains easy spin-on/off automotive style mineral oil filter and 100 micron high pressure filter to remove sediment and other contaminants from mineral oil.
