  • Description
  • Exploitation
  • Technical specifications
  • Delivery set

The universal tool for local measuring the ferrite content in the metal of welds, deposited rust-inhibiting coatings and in the base metal of workpieces, parts and finished products made of austenitic and austenitic-ferritic stainless Cr-Ni steels.

Non-destructive testing of products made of metals and alloys


  • Percentage (%) and ferritic number (FN) scales in all measurement range
  • Measurement of the ferrite content according to ISO 8249-2000, DIN EN ISO 17655,
  • ANSI/AWS A4.2M/A4.2 standards
  • Suitable for laboratory and workshop conditions of nuclear and chemical engineering,
  • shipbuilding and other industries for quality control of stainless steels weldings
  • Wide range of transducers for different applications

Exploitation advantages:

  • Ergonomic housing made of ABS plastic equipped with shockproof rubber pad
  • IP54 dust- and moisture-proof housing
  • Display of the minimum, maximum and arithmetic mean values for set of measurements
  • Optional remote transducer (TQ0.7-01 model) for cladding for ultra-high measurement locality
  • Non-volatile memory
  • USB interface

Operating modes:

Discrete mode
Discrete measurement of ferrite content with displaying of auxiliary information: min/max value, average value, statistics/history.

Continious mode
Scanning of the test object with indication of the current value of coating thickness as well as displaying the min/ max value.
