| Description: |
Hygromaster®
Hygrometer wtih Hygrostick® Sensor and Case
|
Since water intrusion into a formation can decrease borehole stability, the affinity for water of a shale on a drilling fluid is a major concern. The Hygrometer, or Activity Meter, as it is sometimes called, provides a measurement of relative humidity in a closed space above an emulsified
fluid and relates the humidity to the activity of the water. Activity is defined as the chemical potential or the reaction availability of water. Water loss to the formation from an oil-based fluid may be lowered by dissolving salt in the emulsified water, thereby lowering its activity. The Hygromaster instrument measures relative humidity (%rh, range 20 - 100 %rh), ambient temperature (Ta, range 0 - 50°C or 30 - 120°F) and dew point temperature (Tp) of environments and equilibrium relative humidity (ERH) values of materials. The probe or Hygrostick® (No. 153-59-3) has been designed as an interchangeable and easily replaceable item that does not require regular re-calibration. However, the calibration may be checked periodically against a reliable reference solution.
