Optical Path Reduction Module for LISST-100X and -200X
The Optical Path Reduction Modules (PRM) are used with the LISST-100X and LISST-STX to reduce the optical path in the field without the need for permanent optical path reductions. The bolt-on PRMs are available to reduce the optical path by 50%, 80%, and 90% for the LISST-100X and 50% reduction for the LISST-STX.
Please be aware that you need a Large Volume Test Chamber for clean-water background measurements when you are using a PRM. See below for more information on the Large Volume Test Chamber.

Large volume test chamber
Large volume test chamber for use with LISST-200X or LISST-100X with Path Reduction Modules. The chamber has an O-ring seal that allows the optics end of the instrument to be submerged while the instrument is horizontal on the bench. This chamber is highly recommended when using the Path Reduction Modules.
Part # SEQ-A-L100X-CHLG and SEQ-A-L200X-CHLG for the LISST-100X and LISST-200X, respectively.
Full Path Flow Through Chamber
The Full Path Flow Though Chamber is installed on to the optics of the standard-path LISST-100X or LISST-200X. The chamber allows a sample to be pumped through the chamber. When combined with a pump and stirred sample container the Full Path Flow Through Chamber allows the submersible LISST-100X or LISST-200X to be used as a laboratory particle size analyzer.
Part # SEQ-A-L100X-CHFP or SEQ-A-L200X-CHFP
Full Path Mixing Chamber for LISST-100X
The Full path mixing chamber is installed on to the optics of a standard path (5cm) LISST-100X. The chamber has a volume of approximately. 100ml with built in magnetically coupled mixer and drain. Adjustable speed controller and power supply provided. The Mixing Chamber allows the submersible LISST-100X to be used as a laboratory particle size analyzer.
Part # SEQ-A-L100X-CHMX
Small Volume Flow Through Chamber for LISST-100X
The Small Volume Flow Through Chamber reduces the optical path length to 1 cm for higher maximum concentrations. It is optimized for pumped flow through applications and it seals on optics of standard 5 cm path instruments only. When combined with a pump and stirred sample container the Small Volume Flow Through Chamber allows the submersible LISST-100X to be used as a laboratory particle size analyzer.
Part # SEQ-A-L100X-CHSV

Integrated Power and Communications Cables
Integrated Power and Communications cables are available for the LISST-100X / LISST-STX / LISST-Deep in lengths of 20, 30 and 50 meters. The yellow jacketed cable has a breaking strength of 1000 pounds. The standard underwater connectors for communications and power are molded to the cable.
Part # SEQ-A-L100X-CBL20, SEQ-A-L100X-CBL30, and SEQ-A-L100X-CBL50 for 20, 30 and 50 m lengths.
Replacement 2-meter Communications Cable
Two meter communications cable with 5-pin underwater connector and DB-9 Serial Port connector for the LISST-100X / LISST-STX / LISST-Deep. Also used for powering (but not communicating with) the LISST-HOLO with external power (110/220 VAC).
One cable is included with all new LISST-100X, LISST-STX, LISST-Deep, and LISST-HOLO instruments.

Clamps for LISST-100X
Clamps for easy mounting of the LISST-100X, LISST-Deep, LISST-STX, or the LISST-Holo and their external battery pack housings to a frame or simply to a wire for stand-alone profiling.
A set of two two-piece clamps are included with all new LISST-100X, LISST-STX, LISST-Holo and LISST-Deep instruments.
Part # SEQ-A-L100X-CLP2 (set of two two-piece clamps)

Replacement instrument stands for the LISST-100X, LISST-Deep, and LISST-HOLO. One pair of stands ships as standard with a new instrument. Can also be used for mounting the instrument in the field.
LISST-Pump for LISST-StreamSide and LISST-Infinite
The LISST-Pump is a 12 V stainless submersible Mini-Monsoon® well pump that comes with a custom pump controller box for easy integration with the LISST-StreamSide or LISST-Infinite. The pump controller box allows the LISST-StreamSide and LISST-Infinite firmware to control the pump. It also allows the user to select between 3 pump speeds (2.5, 5 and 10 A). The exact speed setting is to be determined in the field once the vertical and horizontal distance from the pump to the instrument is known. Flow speed in the tube must be kept above 0.6 m/s (2 ft/s) to prevent settling of particles.
Part # SSA-LSS-PMP
Frames and Cages for LISST deployment
Sequoia does not manufacture or sell frames or cages for the LISST instruments. However, numerous other companies can build custom frames for your LISST for any type of deployment – profiling, mooring, towing etc. For example, the frames on the picture were built for a LISST-100X by Mooring Systems, Inc. in Cataumet, MA.
Contact Mooring Systems if you need a frame or cage for any of your LISST instruments.
