This apparatus is used to determine softening point of bitumen. Ring and ball apparatus is used to determine softening point. It is that temperature at which a sample of bituminous material loaded by a 9.5mm dia steel ball drops at a distance of 25mm.

Salient Features:

• The apparatus consists of steel bracket with a sliding plate support.
• The support has two holes of 10mm dia on which a Ring and Ball guide can be kept.
• A central hole on this plate is for inserting thermometer. Supplied with a glass beaker approximate 8.5cm. I.D., 12cm high and a hand stirrer and 2 nos. 9.5mm dia steel balls.

Ring And Ball Apparatus (Electrical): Same as above but supplied with a thermostatic hot plate. suitable for operation of 230 V A.C.

Accessories:

• Thermometer IP 60C range 2ºC to 80ºC
• Thermometer IP 61C range 30ºC to 300ºC x 5ºC.
• Electrical Stirrer with stand & blades to gently stir water in the beaker.
• Suitable for operation on 230V AC
