Measurement method: Platinum plate method
Measuring range: 0-400mN/m note : 1Mn/m=1dne/cm
Minimum resolution: 0.01mN/m
Standard deviation: ±0.04 mN/m (the second distilled water at 20 degree
Repeatability: ±0.04 mN/m (the second distilled water at 20 degree
Display mode: LCD display
Temperature range: 15-60 degree with constant temperature bath,(the constant temperature bath is optional)
Best time of reading value: Generally it is 3-5 seconds
Data output: RS232C or USB (optional)
If the sample for testing has larger viscosity or contains surface active agent, different sampling time can be adopted according to be requirements of customer
Voltage: AC220V 1A or 110V

1.automatic measuring,error can be decreased 2.the equilibrium value of surface tension can be read automatically 3.absolute exact one -key resetting
4.One-key calibrating can be realized with attached standard weight rapidly and exactly 5.It fully complies with the basic principle of Willhelmy Plate method and can actualize the measuration in the following cases: 6.Surface tension varies in different time because of the existence of an surface active agent
7.to measure some high viscosity liquid ( the equilibrium value can be read automatically) 8.to measure the tension on an interface between two different liquids that one can not dissolved in the other one, such as oil and water 9.the sensor can respond dater for carrying with high accuracy, and thus it becomes possible to supply reference dater for carrying out a favorable reproducibility.
10.operating simple without being controlled by any external computer
11.the deviation of the instrument is very low because of it own structure which ensure that the errors measuring can be controlled effectively 12.a constant-temperature sample cup, a sample thermometer and an external constant-temperature tank can be optional equipped to the tensiometer.
