The DSY-412 Density Tester is a digital instrument designed for precise measurement of petroleum product density in laboratory and field environments. It operates on the oscillating U-tube principle, measuring mass per unit volume across a range of 0.5 to 3.0 g/cm³ with a resolution of 0.001 g/cm³. The device includes automatic temperature correction based on internal sensors, eliminating manual correction tables for ASTM D1298 or ISO 3675 compliance.
The core sensor is a borosilicate glass U-tube with integrated piezoelectric oscillators, protected by a stainless steel housing. The instrument supports calibration using certified reference liquids such as distilled water and air. It does not include internal memory for batch storage or network connectivity. The display is a backlit LCD, and operation requires manual sample loading via a syringe or pipette. No built-in pumps or automated sample handling are present.
This tester is used by petroleum refineries, fuel quality control labs, and chemical research facilities in Asia and the Middle East. Buyers include petrochemical quality managers, environmental testing labs, and calibration service providers. Packaging is a foam-lined wooden crate. Trade terms are not stated in the listing; buyers must confirm whether FOB Dalian or CIF applies. Lead time and MOQ are not provided and must be requested directly.

Before ordering, confirm the instrument’s calibration protocol and whether it includes traceable certificates for reference fluids. Verify that the U-tube material is compatible with your sample types, especially if testing fuels with high sulfur or aromatic content. Request a user manual to confirm the temperature correction algorithm matches your required standards.
Confirm Incoterms, packaging integrity, and lead time directly with the supplier. FOB Dalian is likely, but shipping insurance for fragile instruments is critical. Lead times are typically 3 to 5 weeks, but custom calibration or export documentation may extend this. Payment terms are not stated; expect T/T in advance or LC for international orders.
Upon delivery, inspect the instrument for transit damage and verify the serial number. Perform a two-point calibration using distilled water and air. Record the results and compare them to the factory calibration certificate. Retain all documentation for audit purposes. If measurements deviate beyond ±0.001 g/cm³, request re-calibration before use.
