How the Tar Viscometer Is Set Up
The test cup drops into the central tube of the bath, which also locates the stirrer. Immersion heating elements warm the bath under the dimmerstat, and the stirrer, with its curved shield and insulated handle, stirs the bath; a thermometer fits in its socket. Once the sample is at the test temperature, the ball valve is lifted and held on its swivel support, and the time for a fixed volume to run out through the cup orifice is the viscosity in seconds. The drain valve empties the bath afterwards.
Models, Spares and Thermometers
One model carries the 10 mm cup and ball valve and the other the 4 mm pair; both are heated electrically. Spare 10 mm and 4 mm cups and ball valves are available, and the IP 8C, IP 9C and IP 10C thermometers are extras.
