Wire Loop For Glow Wire Test Apparatus
For Thermocouple Diameter 1.0 mm

Model GW11 Features:

  • Wire loop is fabricated from > 77% Nickel and 20 ± 1% Chromium
  • The dimensions of the glow wire loop are compliant with IEC 60695-2-10:2013, Figure 1
  • The Diameter of the glow wire loop is 4 mm ± .07 mm (before bending)
  • The tips are Mirror Polished to enable easier cleaning
  • The hole diameter is 1.1 mm in order to fit a 1.0 mm diameter thermocouple
  • Each glow wire loop is pre-annealed in a protective atmosphere for more than 10 hours. This
    saves valuable time for the test engineer when annealing the glow wire loop. Tests then can be
    immediately performed
  • The glow wire loops are easily replaceable
  • Each glow wire loop is engraved with a unique serial number to ensure its traceability and
    certified ISO 17025:2017 calibration
