Semi-Automatic Ring and Ball Apparatus by RadialTec

The laboratory semi-automatic device for determining the softening point of oil bitumen RT-MB-001/SA has a reliable and durable design. It consists of the body of the device, where the controls are located, a display for displaying the settings of the device and displaying the measurement results, a magnetic stirrer with the ability to adjust the intensity of mixing of the liquid in the glass. A stainless steel heater and a PT100 temperature sensor are located in the upper movable part of the housing, which allows you to measure temperature values with an accuracy of 0.1 ⁰С. The body of the heater with a temperature sensor has a latch in the raised and lowered state, which allows you to conveniently insert and position the glass with bitumen samples under test before starting the test. The operation of the magnetic stirrer is automatically stopped when the heater housing with temperature sensor is in the raised position. Maintaining the required rate of heating of the liquid in the glass is carried out automatically by the device, thanks to microprocessor control with feedback and constant regulation of the heater power. The test results are fixed by pressing the corresponding button. The results of determining the softening point of both samples are displayed on the screen after the end of the test. All elements of the device are made of corrosion-resistant materials, which allows you to save its appearance and mechanisms from the effects of water, which may fall on the device during its use.

The laboratory semi-automatic device RT-MB-001/SA is designed to determine the softening point of oil bitumen using the ring and ball method according to GOST 4044-2001 "Viscous oil road bitumen. Specifications", GOST 11506-73 "Method for determining the softening point of oil bitumen by ring and ball" and DIN EN 1427" Bitumen and bituminous binders - Determination of the softening point - Ring and Ball method". The device allows you to determine the softening temperature of bitumen in the temperature range from 20⁰С to 80⁰С when using distilled water as a liquid, and from 20⁰С to 150⁰С when using glycerin as a liquid.
