Introduction:

adopting ASTM D971 “platinum ring method(Du nouy ring)”, tests interfacial tension for various liquids (between liquid and air) and also that between mineral oil and water(between liquid and liquid) by means of automatic control of internal microcomputer under circumstances of nonequilibrium. It only needs you pour the sample into sample cup and then press “start” button. Then the tester will finish the whole test and calculate the tension value automatically according to concrete input parameters. 

1.Platinum plate(Du nouy ring) method; easy and convenient operation.
2.Automatic digital test to reduce personal operation error.
3.Full scale reset. One button for zero clearing; instant achievement; zero temperature with no drift.
4.Full scale automatic revise: accurate and reliable data with good repeatability.
5.Direct display for the tension value of sample; no need more calculation.
6.Compact structure; working independently with no need of additional equipment like external computer.
7.Can detect surface tension changes caused by different time especially when there is any surfactant or volatile substance.
8.Automatically test middle or high viscosity liquid sample and get balance results.
9.Can test interfacial tension between liquids which don’t mixed like that between oil and water.
10.Can completely replace traditional mechanical surface tensiometer.
11.High cost performance.

Chongqing TOP is a professional leading manufacturer and supplier of oil purifiers and various related testers. We consists of departments respectively for technological development, machinery manufacture, instrument manufacture, quality control etc. On basis of mature development and manufacture technology and highly qualified production management team, the products own high quality, easy operation, excellent performance and lone service life.

 We are able to greatly extend oil and component life, which will significantly reduce maintenance and down time costs.we are proud to offer our products and services to assist our clients in achieving optimal machine performance.

TOP Oil Purifiers uses single or multi-stage filtration to remove, particulate, free water, and small quantities of dissolved water if necessary. The systems are usually customized to suite the specific customer application. Oil "regeneration", "reclamation", "recycling" are all terms used to describe the process of restoring used, aged, contaminated oils to "like new" reusable condition. The reclamation process removes free water, most dissolved water, dissolved gas, particulate, carbon contamination, acids, oxidation by products, most color bodies, wear metals, and most additive chemicals.

TOP Oil Testers works on the development, production, market, technical and after-sale service for petrochemical analyzers, transformer substation electrical testing equipment and circuit detecting equipment. Main products are water content testers, surface/interfacial tension testers, flash point testers, kinematic viscosity testers, oil acidity testers, insulation oil dielectric strength testers, transformer characteristics testers, relay protection testers, high voltage testing equipment etc.
