Determines the Softening Point of Bitumen in the range from 30 to 157°C (86 to 315°F) using the ring and ball apparatus immersed in distilled water (30 to 80°C), USP glycerine (above 80 to 157°C), or ethylene glycol (30 to 110°C).
Constant temperature bath for kinematic viscosity testing of petroleum products. Accommodates six round 2″ (51mm) dia. viscometer holders. Bath temperature stability of ± 0.02 °C as per ASTM requirements. Test temperatures of up to 150°C (302°F) can be selected. Temperature limit control permits the operator to select an overtemperature cutoff point to protect against accidental overheating. Control unit includes immersion heater, circulating stirrer and temperature probe. Composition top plate rests on a 12×12″ (30.5×30.5cm) or 12×18″ (30.5x46cm) Borosilicate Glass jar. Order capillary viscometers, viscometer holders and thermometer separately.
