FAQs

1. How does the transparent bath in the Density Tester enhance the testing process?

Density Tester features a transparent bath that allows users to clearly observe sample positioning, fluid behavior, and the hydrometer’s immersion level throughout the test. This real-time visibility helps identify air bubbles, misalignment, or sample inconsistencies that could affect accuracy. The clear bath design also enhances lab safety by allowing early detection of spills or contamination. For educational or demonstration purposes, it provides excellent visual feedback, making it ideal for training environments.

2. What sample preparation steps are critical before using the Density Tester for density testing?

Density Tester requires that samples be properly prepared to ensure accurate results. The sample must be free of air bubbles, water contamination, and residues from previous tests. It should be allowed to reach thermal equilibrium with the bath before hydrometer insertion. Using a clean, dry cylinder and pre-conditioning the sample for a few minutes in the bath minimizes thermal lag and improves measurement precision.

3. What kind of samples can be tested using the Density Tester ?

The Density Tester is ideal for testing petroleum-derived liquids such as crude oil, diesel, gasoline, kerosene, and lubricants. It is particularly suitable for substances that require density measurement at controlled temperatures for quality control or grading. The tester accommodates standard hydrometer sizes, making it compatible with a broad range of liquid types. Additionally, non-petroleum liquids with similar properties may also be tested if they are compatible with the bath material.

4. Why is temperature control critical in the Density Tester during hydrometer-based testing?

The Density Tester delivers precise temperature control because even a 1?°C deviation can significantly affect the measured density of petroleum products. The device uses a Pt100 platinum resistance sensor and an intelligent temperature controller to maintain bath temperature with ±0.2?°C accuracy. This ensures that the hydrometer reading reflects the actual density at the reference temperature. By eliminating the need for temperature correction, it increases both test reliability and efficiency.

5. Does the Density Tester require calibration, and how often should it be done?

Density Tester should be calibrated regularly to ensure accurate, repeatable results. The built-in thermometer must be compared against a certified reference thermometer, and the controller should be validated periodically. High-usage environments may require monthly calibration, while less frequent use may only need quarterly checks. We can provide traceable calibration guidance or certificates upon request to support regulatory compliance.
