LISST Accessories





BIOBLOCK - a mechanical anti-fouling accessory for the LISST-100X and LISST-25X.  Sliding copper shutters in front of the windows limit fouling to a minimum. BIOBLOCK is controlled by the LISST-100X or LISST-25X to open before a measurement takes place and close again after the measurement.
    
   LISST-100 Alkaline Battery Pack
The replacement alkaline battery pack for the LISST-100/ST has 24 alkaline batteries assembled into a custom battery pack to provide the +15, +18 , and –18 volts required. The battery pack is not rechargeable.
 
    

LISST-100X Alkaline Battery Pack
The replacement alkaline battery pack for the LISST-100X/STX has 24 alkaline batteries assembled into a custom battery pack to provide the +9 and -9V required. The battery pack is not rechargeable.





   LISST-100 replacement Lithium Backup battery
The LISST-100 Backup battery is used to protect the datafile memory in the event of a main battery power failure or disconnect. The lithium battery come with the mating connector installed and ready for assembly.
 
    
 
50% PRM
 Optical Path Reduction Module
The Optical Path Reduction Modules (PRM) are used with the LISST-100/-100X and LISST-ST/-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%.

  LISST-100X/LISST-STX External AC Power Supply
External AC power supply for powering LISST-100/ST. International power compatible.
 
    
  Full Path Mixing Chamber
The Full path mixing chamber is installed on to the optics of a standard path (5cm) LISST-100 or -100X. The chamber has a volume of aproximately. 100ml with built in magnetically coupled mixer and drain. Adjustable speed controller and power supply provided. The Mixing Chamber allows the submersible LISST-100/-100X to also be used as a laboratory particle size analyzer.
 
    
 

 Small Volume Full path Flow Through Chamber
The Full Path Flow Though Chamber is installed on to the optics of the standard path (5cm) LISST-100 or -100X. The chamber allows sample to be pumped through the chamber. When combined with a pump and stirred sample container the Flow Through Chamber allows the submersible LISST-100/-100X to be used as a laboratory particle size analyzer.
 
    
 





 Adjustable Thin Cell Flow Through Chamber
The Thin Cell Chamber has an adjustable optical path from 10mm to 2mm. The thin cell allows for higher concentrations than the full path instrument. The mounts in the optical path but it must be submerged in clean water during operation. The standard Large Volume Test Chamber can be used to submerge the thin cell. When combined with a pump and stirred sample container the Thin Cell Chamber allows the submersible LISST-100 to be used as a laboratory particle size analyzer.
 
    
  Integrated Power and Communications Cables
Integrated Power and Communications cables are available for the LISST-100/ST 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.
     
 
    
  Replacement 2-meter Communications Cable
Two meter communications cable with 4-pin underwater connector and DB-9 Serial Port connector.

 
    
  High Performance Conductivity and Temperature Sensor
High Precision Conductivity and Temperature can be added to the LISST-100 by adding a SeaBird SBE-37SI sensor to the LISST-100. The integrated sensor provides high precision conductivity and temperature for each size distribution. The values are stored in the standard LISST-100 datafile. High performance depth sensor can also be added to the SBE-37SI.
 
    
 Large volume test chamber for LISST-100/-100X
 Replacement Large volume test chamber
Replacement large chamber that is provided standard with the LISST-100/-100X and LISST-25/-25X. Has o-ring seal that allows the optics end of the instrument to be submerged while the instrument is horizontal on the bench. Available for both the LISST-100 and LISST-25.
 
 
Test chamber for LISST-25/-25X
   
    
  Custom Optical paths
Custom optical paths are available for both the LISST-100 and LISST-25. Custom paths that have been done included 25mm, 10mm, 5mm, 3mm, and 1mm.


 
    
  Clamps
Clamps for easy mounting of the LISST-100X to a frame or simply to a wire for stand-alone profiling.


 
    
    
    
    
    
    
    
    
    
    
    
    
LISST-Portable re-design
Sequoia's LISST-Portable is undergoing a re-design in order to be equipped with a touch panel display similar to the one on the LISST-StreamSide. Also, all dataprocessing will now take place on-board in real-time so no data post-processing is necessary. The first units will ship in October 2008.
