For determining the temperature at which a sample of bituminous material loaded by a , drops a specified distance when heated under specified conditions.The new design of Ring and Ball Apparatus is compact user friendly and has better asthetics. It has magnetic stirrer with heating facility and digital display of temperature.New Feature: You can take the reading by just pressing a button that is provided in the control panel (First Time In IndiaA) Note: We do not provide glass beaker with the equipment. The temperature range is Ambient +5 degree to 95 degree celcius.

Heat of Hydration apparatus is used for determining heat of hydration of cements by measuring difference between heat of solution of dry cement and heat of solution of a separate sample partially hydrated for 7 days & 28 days. Constant-speed stirrer maintains uniform temperature throughout liquid and supplies sufficient agitation to keep solid reactant suspended in the acid mixture. This equipment consists of insulated wood case, vacuum jar with stopper; digital thermometer (least count 0.1 degree) plus holder, glass funnel; stirring paddle and chuck.

For the empirical measurement of Saybolt Viscosity of petroleum products at specified temperatures.This is also used for determining the Saybolt Furol viscosity of bituminous materials. It comprises one each of Cylindrical Oil Cup, Universal Tip, Furol Tip, Bath fitted with immersion heater mounted on a stand, Microprocessor based PID Temperature Controller, Stirrer with shield. Apparatus is supplied complete with insulated handle and thermometer support, receiving flask, withdrawal tube, filter funnel, thermometer support for cup and circular spirit level.

The thin-film oven (TFO) test simulates short-term aging by heating a film of asphalt binder in an oven The effects of heat and air are determined from changes incurred in physical properties measured before and after the oven treatment by other test procedures.

Additional Information:

• Delivery Time: Ready Stock
• Packaging Details: It will be properly packed after satisfactory inspection

This unit simulates the hardening that affects binder during its mixture with aggregates in the plant and during the finishing & rolling of the bituminous layers (Short Term Ageing). Provides the binder sample ready for change in mass determination and for other tests that characterize the binder about the resistance to short term ageing.
