Thermocups are designed for controlling the temperature of a mud sample while taking readings with a rheometer or viscometer. Normal heat-up time is 15 minutes and the pilot light turns off when the well reaches the set temperature. Drilling fluid has a low thermal conductivity, so it must be agitated in order to reach a uniform temperature within a reasonable length of time.

• Thermocups contain removable stainless steel cups for holding the fluid
• To avoid overheating

Clean the thermocup thoroughly after each use. If your thermocup has a stainless steel cup, remove it and wash it with soap and water. Otherwise, wash the thermocup well with soap and water, being careful not to immerse the thermocup in water.
