Improvement of Repeatability and Reproducibility
SEA1200VX provides improved repeatability and reproducibility by employing the high count rate Vortex detector.
Standard Deviation from 10 readings
The tables below show readings of hazardous elements in resin and stainless alloy measured by the SEA1200VX. SEA1200VX employs the Vortex high count rate detector has better repeatability and reproducibility than the conventional models.
