Online Etching Solution Specific Gravity Measurement TWD-EW-ONLINE
Principle: Referring to the standard of GB/T611, T2423, T22230, T5009, ISO 6353, 758,
and by adopting hydrostatics buoyancy method, Bernoulli principle of hydrodynamics to online monitor the specific gravity change of etching and washing solution, and then by applying Lagrange interpolation method, the dynamic data of online etching and washing solution concentration can be converted.
Function:
With the special design of buffering device TP-30, it is fully consistent with the hydrostatic principle; the data tested will be more accurate.
