Measurement of Solder Samples
SEA1200VX achieves highly sensitive results by measuring Pb-free solder samples at providing superior "limit of detection" and excellent repeatability.
Lead (Pb) in Pb Free Solder by SEA1200VX
Excellent linearity of the calibration curve for Pb-free solder created by optimal measurement conditions achieves a detection lower limit of 7.9ppm Pb at a measuring time of 300 seconds.
Excellent Repeatability
SEA1200VX achieves a significantly higher repeatability of CV 1.9 % at a measuring time of 100 seconds using an MBH Pb-free solder standard sample.
