This advanced Ferrite Measuring Device is an essential tool for precise ferrite content measurement in austenitic and duplex steels. Featuring a bright, high-contrast OLED display, it shows measurements in both FN and Fe% with a range of 1-100 Fe% or 1-140 FN. The device excels at continuous measurement capabilities, allowing users to scan surfaces while automatically calculating minimum, maximum, and average values. With its compact size of 3.70 x 3.70 x 1.10 inches and lightweight design at just 0.16 lbs, it's perfectly portable for field use. The instrument offers impressive storage capacity for 4000 measurements and includes wireless connectivity for seamless data transfer to Android, iOS, or Windows devices. The device operates for up to 30 hours on a single AA battery and features an intuitive multi-language interface. Three calibration standards traceable to NIST ensure measurement accuracy within 5%. Perfect for welding quality control, this device helps determine whether weld seams contain sufficient ferrite content for optimal strength.
