Cleaning and Service Tips

Most of the problems that occur with the Model 3065 Wettability Tester are due to
inadequate cleaning. The blade assembly, mixing cup, and probe leads must be thoroughly
cleaned after each test. If the blade assembly becomes contaminated with cement, the
assembly will bind causing the motor to over heat. Care should be taken to clean between the
heating jacket and cup if fluid is spilled or splashed.
First remove the nut on the bottom outside with a 7/8" socket. Pull the blade assembly
through the cup. Remove the small "acorn" nut with a 3/8" wrench. Replace the blade with a
new one. Tighten acorn nut onto new blade. Re-insert the blade assembly through the cup.
Tighten the nut on the bottom outside.

Calibration Procedure

Thermocouple
1. To check thermocouple calibration, heat water in the mixing cup to 100
2. Using a NIST traceable thermometer, check that the temperature is actually 100
3. Repeat at 175
