Adopting thin wire loop with certain height and sheet metal to replace the original platinum wire loop or platinum wire edge, which is undeformed or not be damaged for using over again.
The wire loop is designed and tested in its outline for special purpose, so the result directly measured has no need of correction. It can obtain a reliable and accurate result.
Application of silicon single-crystal resistance strain gage to measuring the surface tension of liquid that is contacted with metal makes the apparatus high in sensitivity and perfect in linearity and stability. The value can be displayed by a digital voltmeter.
Glass ware: 2.00cm in diameter
Wire loop: aluminum alloy loop with 3.496cm of outside diameter, 3.310cm of inside diameter and 0.85cm of height
Reading display: 200mV voltmeter
Silicon single-crystal resistance strain gage: 0-10g; Sensibility: about 30mV/g service voltage: dc 6-12V
Scale pan and seven pieces of weights of 0.5g.
