The 12th International Conference on Materials and Mechanisms of Superconductivity and High Temperature Superconductors (M2S-2018) was held from August 19 to 24, 2018 in Beijing, China. It is a worldwide high-level event conducted every three years in the field of basic research and application of superconducting materials. China first hosted the fourth M2S conference in Beijing in 1997. 21 Year after that, the M2S conference is held in China for the second time.

Sine Scientific Instruments was honored to be invited into the grand gathering to showcase the products it developed independently, namely the OE series Lock-In Amplifier, Low-noise Preamplifier, etc. Since the Lock-In Amplifier technology has been used widely in the field of superconductivity, the OE series of Lock-In Amplifier developed by Sine Scientific Instruments has drawn wide attention of both domestic and international researchers.
