Fischer Technology SigmaScope SMP10



Handheld instrument for conductivity measurement of non-ferromagnetic metals.


The SIGMASCOPE SMP10 is a compact, ergonomic portable instrument with a shock resistant synthetic housing, a large backlit LCD screen and a user friendly keyboard, with direct access to the most important measurement functions.


The SIGMASCOPE® SMP10 is a hand-held instrument which provides rapid, simple, on-the-spot and if necessary, contact free measurement of the conductivity of non-magnetic metals.

General Purpose Probe


Typically used for sheets, bars and extrusions

  • Minimum Area: 15mm/0.600"
  • Edge Distance: 11mm/0.440"
  • Min Diameter: 2mm/0.080

Special Purpose probe


Typically used for fasters and other small parts.


  • Minimum Area: 3.3mm/0.132"
  • Edge Distance: 0.8mm/0.032"
  • Min Diameter: 2mm/0.080"

The corresponding measurement probe ES40 operates at the measurement frequencies of 60 kHz, 120 kHz, 240 kHz and 480 kHz.


For automatic temperature compensation of the conductivity measurement, the current temperature of the specimen can be measured using either the temperature sensor integrated in the probe ES40 or an optional external sensor.


For the conductivity measurements of very thin Aluminum platings of only about 0.2 mm thickness in the aircraft industry, the SIGMASCOPE® SMP10-HF is available. The measurement frequencies are 60 kHz, 240 kHz and 480 kHz with probe ES40 and 1.25 MHz, with probe ES40-HF.


Fischer is the acknowledged supplier of certified calibrations standards for the European Mints.


Internationally recognized Boeing Standards are used to establish the working standards of the SIGMASCOPE®SMP10.


  • Rapid and simple on-the-spot conductivity measurement  of non-ferromagnetic metals
    (acc. to DIN EN 2004-1, ASTM E 1004)
  • Conductivity probe ES40 for frequencies 60 kHz, 120 kHz,
    240 kHz, 480 kHz. (ES40-HF for 1,25 MHz)
  • Automatic temperature compensation of the conductivity (integrated or external sensor)
  • Automatic curvature compensation for a known curvature diameter (down to 6 mm)
  • We offer certified traceable calibration standards (MS/m,
    %IACS). Our probes were calibrated with these standards. 
  • Fischer is the acknowledged supplier of certified calibrations standards for the European Mints.


Typical fields of application

The electrical conductivity measurement is an important quality assurance component in the manufacture, maintenance or repair of airplanes. 


The electrical conductivity is employed for the production, processing, or inspection of finished goods made of non-ferro us metals.

The SIGMASCOPE® SMP10 can be used, wherever the measurement of the electrical conductivity is important:

  • Airplanes - Aircraft industry to check for stress and wear, e.g., in aluminum alloys
  • Mints - Distinction of false and genuine coins and during coin production
  • Thermally sprayed nonferrous metal coatings
  • Checking the electrical conductivity of copper during the production process or also of aluminum components prior to anodizing
  • Determination of the phosphorous content in copper
  • Degree of purity determination
  • Checking the homogeneity of alloys
  • Scrap sorting

A high-precision measurement is required to determine the electrical conductivity. This requires accurate standards for calibrating the instrument. Fischer offers certified standards (in MS/m, %IACS, traceable to internationally recognized calibration standards) and special standards, e.g., for testing EURO coins or for special applications (e.g., Boeing).
