Flame-Resistant Fiber Probe


Out of stock

SKU: FL-400 Category:

The FL-400 is a heat-resistant fiber optic probe that couples via a fiber and splice bushing to our spectrometers to measure in situ emission spectra. Typical samples include dissolved metals and high-temperature plasmas, but these probes are also useful for measurements close to a high-temperature object like a furnace or flame.

  • Connects using a 21-02 splice bushing to a 400 μm core patch cord for routing to the spectrometer
  • Excellent for measuring emission spectra in sample environments up to 750° C
  • Includes a removable nickel wire loop at the probe tip for observing flame emission spectra from solutions of sodium, potassium, calcium and copper — an excellent teaching tool
