Activity is the measurement of the chemical potential or the reaction availability of a chemical species. Drilled hole conditions in water sensitive shales can be correlated with changes in the activity of emulsified water in oil-based drilling fluids. The use of a hygrometer, a portable relative humidity sensor and indicator, is the preferred method for determining the activity.
Aqueous Phase Activity Kit
The Aqueous Phase Activity Kit is used to determine aqueous-phase activity of emulsified water using an electro hygrometer by the method described in American Petroleum Institute publication API Recommended Practice RP 13B-2. The kit includes special flasks and adapters and premixed saturated salt solutions (relative humidity standards) for use in calibrating the hygrometer.

Hygrometer Digital Thermo
The Thermo-Hygrometer provides readings with high precision in a very short time for both RH and temperature. The detachable RH probe is housed in a rugged ABS cylinder with a thin-film polymer humidity sensor and a signal amplifier. A perforated cap on the probe allows the air to circulate while it protects the sensor. This unit is specially designed for controlled environment applications. The smooth membrane keyboard has 4 keys that make operation simple and quick. A large LCD displays readings in easy-to-read digits each with a symbol next to it to identify the operating mode.
