Q:What measurement methods are supported?

The tensiometer supports the traditional platinum plate method (Wilhelmy) and the platinum ring method (DuNouy). It also offers optional accessories for liquid density measurement.

Q:Does the device require a computer to operate?

No, the machine does not need a computer when operating. It features a 7-inch touch screen for direct operation and data reading, though it can connect to a printer or USB.

Q:What is the accuracy of the surface tension measurement?

The accuracy depends on the model. The Q2000 has an accuracy of 0.1 mN/m, the Q1000 is 0.01 mN/m, and the Q500 reaches up to 0.001 mN/m.

Q:Can the device measure liquid density?

Yes, by using the buoyancy principle and optional standard volume accessories, the device can accurately measure the density of the tested sample within a range of 0-3.000 g/cm3.

Q:What software is included with the device?
