Consistometer HPHT Model 8340

The Model 8340 HPHT Consistometer is designed for laboratories that need to test cement mixtures and additives for use at the hottest temperatures and highest pressures. This instrument is used to test cement thickening behavior under almost any downhole well conditions. Designed with laboratory efficiency and ease of operation as major goals, the Model 8340 design minimizes the two largest contributors that affect instrument runtime: the cool-down time between tests and downtime for maintenance needs.

Chandler Engineering renowned manufacturing and field service experience is evident throughout the design of the Model 8340. The exclusive cooling system shortens the time between tests by as much as 75% as compared with other conventional consistometers. Cool down of a 400˚F test to a safe 100˚F takes only about 15 minutes.

Maintenance on the hydraulic systems is minimized through a design which is easy to clean and uses standard filters. An avionics inspired modular electronics assembly makes unexpected service a snap further minimizing potential downtime. Slurry cup drive reliability is maximized by use of a magnetic coupling system to connect the drive motor to the cup. Consistency is measured with a torsion spring / paddle system. The Model 8340 Pressurized Consistometer is extremely simple to operate with all of the operational controls conveniently located on the front panel.
