Takeaway
VEGA tuning-fork density meters are widely recognized in European and US markets, with their PLICSCOM display and plics+ software ecosystem. PS7400 matches the density accuracy class with China-domestic factory fast delivery, deep customization, and remote diagnostics. For Chinese and Southeast Asia / Middle East / Africa emerging markets, PS7400 is a stronger value-for-money same-category choice.
