Product Description

The Model ZLN-1A Funnel Viscometer is used to measure relative viscosity of the drilling fluids, comparatively with water viscosity. It is widely used in Petroleum or Geology industry, and especially can be used to measure daily drilling fluid viscosity data in drilling field. To some extent, the data measured by the Viscometer are greatly influenced by colloid ratio and gravity, so the data measured by the Viscometer cannot directly compare with that of the Rotational Viscometer, static shear and rheometer.
Qingdao Haitongda Instrument Company offers a complete line of equipment, materials, and supplies for analyzing various drilling fluids and oil well cements in accordance with API Specifications and API Recommended Practices.
