Ring and Ball Apparatus
The new design of Ring and Ball Apparatus is compact user friendly and has better aesthetics. It has magnetic stirrer with heating facility and digital display of temperature, the heating can be adjusted through knob. Suitable for operation on 220 V, 50 Hz, single phase, AC supply. Each unit is supplied with a bath of heat resistant glass and the following:
ZI 4003-A Tapered Rings : 2 Nos.
ZI 4003-B Ball Centering Guide : 2 Nos.
ZI 4003-C Steel Balls of 9.5 mm dia : 2 Nos.
ZI 4003-D Ring Holder : 1 No.
ZI 4003-E Electric Heater (Hot Plate) : 1 Nos
Advanced Temperature ControlUtilizing a microprocessor-based heating unit, the apparatus offers digital temperature control and instant response time. The user can set desired temperatures with high accuracy (0.5C) and observe real-time readings on the digital LED display. This technology enhances the precision required for softening point determination in materials.
Uniform Heating for Reliable ResultsThe integrated magnetic or electric stirrer ensures even heat distribution within the heat-resistant glass bath. This consistent and uniform heating process minimizes thermal gradients, providing reproducible results and maintaining testing reliability for laboratory measurements.
Enhanced Safety and AccuracySafety features include thermal overload protection and an integrated audible alarm that activates upon reaching the softening point. The apparatus is factory calibrated and allows for digital adjustment, ensuring continued accuracy and safe operation during bitumen, tar, or resin testing.
FAQ's of Ring & Ball Apparatus (Semi Automatic):
Q: How does the Ring & Ball Apparatus ensure uniform heating during testing?
A: The apparatus features a heat-resistant glass bath equipped with a magnetic or electric stirrer, which circulates the heated liquid and guarantees consistent thermal distribution throughout the sample for accurate softening point measurements.
Q: What materials can be tested with this semi-automatic Ring & Ball Apparatus?
A: It is suitable for determining the softening point of a variety of substances, including bitumen, pitch, tar, wax, and resins, following ASTM D36 and IS 1205 standards.
Q: When should the audible alarm be expected to sound during an experiment?
A: The integrated audible alarm is programmed to activate automatically when the softening point of the tested material is reached, allowing the operator to promptly note the result without manual monitoring.
Q: Where can this apparatus be installed for laboratory testing?
A: Designed for benchtop mounting, the apparatus fits standard laboratory setups, making it ideal for use by manufacturers, suppliers, traders, or research laboratories across India.
Q: What is the process for conducting a test using this equipment?
A: After placing specimens in the brass rings and steel balls as per standard specifications, the user sets the desired temperature range and starts the heating cycle. The semi-automatic system manages heating and monitoring, while the operator manually positions the balls, all controlled via push-button/manual interface.
Q: How does factory calibration benefit laboratory users?
A: Factory calibration ensures that each apparatus is preset for accuracy; however, users retain the ability to adjust calibration when required, providing reliable results and supporting compliance with testing standards.
Q: What are the main advantages of using the semi-automatic model over manual units?
A: The semi-automatic apparatus streamlines heating control, increases accuracy with digital features, reduces operator error with alarms, and delivers dual simultaneous specimen testing, making laboratory processes more efficient and trustworthy.
