This surface tensiometer, which is widely used in quality control processes related to surface interfacial tension,such as emulsifier or wetting agent and cleaning agent testing. It is reliable, easy to use, independent of computers and other equipment, and can provide accurate and reliable analysis when testing a large number of samples. This surface tensiometer is controlled by automatic moto r to realize fast switching of accurate surface tension measurement
-
Application field 1) Oil aging test, especially transformer oil (ASTM D-971) 2) Determination of Surfactant Effectiveness in Wetting Agents and Cleaners Test Surfactant Solution Concentration. 3) Canning approval and cleaning validation in the food industry. 4) Interfacial tension measurements for quality control and optimization of emulsifiers. 5) Cooling lubricant surface tension test
-
Measurement methods ★ Use the Du Nouy ring method to measure the surface tension and interfacial tension. ★Manual testing of critical micelle concentration. (CMC)
About VTSYIQI Liquid Surface Tension Meter Tester Surface
Instrument main features: 1. Compact structure, independent working; 2. Full measuring range clear: instant one-key clear, no deviation at zero position; 3. When measuring with the plate method, the value displayed is the surface/ interface tension value of the sample, and recalculation is unnecessary; 4. When measuring with the ring method, the peak value can be kept, and will be automatically converted into the surface/ interface tension value via Excel or any data process software; 5. Change of sample surface tension with time can be measured; 6. The traditional mechanic surface tension meter can be fully replaced; Instrument application range: - Ink, printing ink, oil paint industry: analyzing the wettability in printing and coating, product research and development, quality control - Cleaning agent industry: analyzing the absorbing rate, property and a suitable concentration of any surface activating agent - Cosmetic industry: analyzing the dispersibility, stability and wettability of any emulsion or suspending agent - Electroplating industry: analyzing the surface tension of any electroplating solution for quality control- Petroleum industry and auxiliary agent industry, etcTechnical parameters:Measuring modes:Pt loopOperating mode:Sampledisc manual elevating, fully automatic measuringMeasuring range:0~600mN/m Sensitivity:0.1 mN/mRepeatability:≤±0.2mN/mData display:Wide visual angle ,backlight LCD screenTemperature range:Standard room temperature or 5℃~90℃(optional sample constant jacket cup and constant temperature circular bath are necessary) Measuringtime:Lowconcentrationsample:3~5sec for Pt loop methodData output:RS232CExternal dimensions:320*200*340mm Net weight:7kgPower supply:110V~220V,60Hz/50Hz
