Model FPT-750 - Series Single Pass Transmission Probes Brochure

Hellma Axiom`s FPT Series probes set the standard for robustness and photometric accuracy. Both the FPT–750 laboratory probe and FPT–850 process probe employ a single pass through the sample thus eliminating stray light and maximizing the sample gap for a given transmission pathlength. In addition, Hellma Axiom’s patented optical design eliminates the need for optical fibers within the probe, eliminating fringing effects and providing a high degree of stability over a wide range of temperatures and pressures.^{1, 2}
