Fann Instrument Company introduces a new Electrical Stability Tester for use with oil-based drilling fluids. Mud engineers depend on the electrical stability test to monitor a fluid's emulsion stability and oil-wetting capability. The new tester is simpler to operate and can be used in the lab or in the field anywhere in the world.
The Model 23E Electrical Stability Tester (EST) conforms to the test procedure described in API Recommended Practice 13B-2. It operates on external power or two nine volt batteries. The Model 23E is calibrated in peak volts which is the maximum voltage that the fluid experiences between the two electrodes. Peak voltage may be converted to Root Mean Square (RMS) voltage by multiplying the peak voltage by 0.7071.
Features: Portable operation on two (2) nine volt batteries. Battery life Approximately 250 tests. Self-calibration for immediate performance checks. Large backlit display is easy to read, even in low light. Operating temperature range. 32° to 122°F (0° to 50°C).
