This Automatic Surface Tensiometer measures the surface tension of liquids and mineral oils against water using the ASTM D971 ring method, with precise temperature control for accurate results. The instrument features an LCD display, keyboard operation, and single-chip program control for automated detection and calibration, simplifying setup and use in laboratory settings.
The technical parameters include a measuring range of 5 to 95 mN/m, with a sensitivity threshold of 0.1 mN/m and an accuracy of ±0.5 mN/m. Typical surface tensiometers operate within this range, with standard measurement speeds of 0.3 to 1.0 mm/s for the ring method. The device runs on a 220V ±10% power supply at 50Hz ±5%, which is standard for laboratory equipment in many regions.
Designed for quality control and research applications, this tensiometer is used in industries such as petrochemicals, pharmaceuticals, and materials science. Buyers include testing laboratories, universities, and manufacturing facilities that require precise surface tension measurements for process optimization or compliance testing. The integrated design ensures easy maintenance, a key consideration for high-usage environments.

Before placing an order, verify that the tensiometer’s measuring range and accuracy meet your specific application requirements, such as testing low surface tension liquids or high-precision analyses. Request documentation on calibration procedures and traceability to ensure compliance with your laboratory’s standards or industry regulations.
Confirm the supplier’s lead time for delivery, as laboratory instruments often have longer production or shipping times. Discuss Incoterms, such as FOB Changsha or CIF to your port, to clarify shipping responsibilities and costs. Payment terms should be negotiated in advance, with options like TT or LC commonly used for international transactions of this nature.
Upon receipt, inspect the instrument for damage and verify that all accessories, such as calibration weights and manuals, are included. Conduct initial calibration tests using standard liquids, like distilled water, to confirm the tensiometer’s accuracy. Establish a maintenance schedule, including regular cleaning of the platinum ring and periodic recalibration, to ensure long-term reliability and performance.
