The MicroNIR PAT-L immersion spectrometer is based on the MicroNIR PAT-U process spectrometer, with design adaptations that include: y Full integration into a fixed gap immersion probe y High-efficiency light pipe design y Inert gas backfill eliminates water vapor interference and condensation y Hardwired USB cable for reliability y Optional removable cooling jacket The PAT-L is a fully integrated spectrometer-probe. The spectrometer section is rated IP65/IP67 and the immersion probe section is rated at up to 250 bar. Optical specifications are identical to the MicroNIR PAT-U and may be found on the PAT-U Data Sheet. The cooling jacket, with hose barb connections, allows coolant to circulate and maintain the spectrometer within its operating temperature range while the probe is in contact with hot fluids or in high ambient temperatures. Maximum working temperatures depend on the probe length and material and the coolant used. The MicroNIR internal temperature operating range is 0 to 50ºC. The PAT-L immersion probe section is based on the Hellma Excalibur HD FPT 26, a well-proven, heavy-duty industrial probe.

Features

• All-in-one optical design for ease of installation and cleaning
• Continuous liquid process monitoring in vessels, tanks and pipelines
• Rapid acquisition time for real-time reaction monitoring and high flow liquid streams
