These process-ready transmission probes are ideal for online measurement of sample streams in demanding environments. Available in various pathlengths and materials, they possess linearity superior to that of our standard transmission dip probes, and can be used as part of a process system or combined with our spectrometers and accessories to create real-time monitoring systems for a variety of transmission applications.
The probes transmit light through the sample by offset-folding the beam 180º and back via a protected reflector. The transmitted light is carried back to a spectrometer where the absorbance measured can be converted to concentration units.
- Connects to light source and spectrometer with two 600 μm fibers
- Useful when sample concentrations are higher than typical
- Single-pass probes are best for pathlengths from 1 – 6 mm
- Double-pass probes are best for pathlengths from 5 – 20 mm
