Single & Double Pass Transmission Probes

Our process-ready transmission probes enable inline measurement of gas or liquid sample streams in demanding industrial environments. The transmission probes direct light energy from a source SMA-905 connection through a sample and return the light energy to a measure SMA-905 connection via a prism. The Single Pass Transmission Probe is designed to facilitate absorbance measurements when the concentration within a gas or liquid sample stream is high. The Double Pass Transmission Probe is designed to facilitate transmission and/or absorbance measurements when the concentration within a gas or liquid sample stream is low.
