Product details
Features:
1: This surface tension experiments Using advanced strain type or electromagnetic force balance sensor, with high precision, high repeatability .
2:, fast data acquisition rate, up to 10 per second update data, more accurate description of the dynamic tension curve;
3:embedded a variety of professional tension correction model for the measurement of high accuracy to provide adequate protection;
4:5-inch wide touch screen control, the current temperature, the current tension, peak tension, equivalent tension and other information integrated display, the operation is very simple;
5.platinum plate, platinum ring two test methods
6:Full automatic operation, eliminate all human error. Platinum plate automatically lock liquid interface, platinum ring show tension curve, peak tension lock automatically, without any conversion, direct screen tension values.
7:It has full range automatic correction, supports Farmar weight correction and tension adjustment for pure water and ethanol.
8:Stepper motor control automatic lift platform, precision can reach level of microns, up and down smoothly, without noise, rising and falling speed is adjustable.
9, semi-circular arc switch door, isolated from the impact of external air;
10, platinum plate, platinum ring hoisting bracket, the user easy to uninstall, ready to use the standard weight calibration force value
11, One key to peel function, the number does not run, zero no drift;
12, the temperature automatically compensated to water, ethanol as a standard, automatically converted to 20 ° C specimen tension value;
13, convenient temperature control interface, configure the thermostat tank can accurately control the sample temperature;
14, a strong data collection and management software, without manual recording; users can always query the historical data, and lead into EXCEL data format, user-friendly secondary data Development
15:Meeting the following standards, but not limited to the following criteria:ISO 1409-1995 The surface tension determination of the plastic, rubber, polymer dispersions and latex.
ISO 6295-1983 The oil to water interfacial tension determination of oil products
