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.
The LISST-100X has a smaller number of batteries assembled int oa custom pack to provide the +9 volts 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.

90% reduction
Optical Path Reduction Module
The Optical Path Reduction Modules (PRM) are use with the LISST-100 and LISST-ST to reduce the optical path in the field with out the need for permanent optical path reductions. The bolt on PRMs are available to reduce the optical path by 50%, 80%, and 90%.










 
LISST-100/LISST-ST Memory Upgrade
LISST-100/ST Memory upgrade increase the total number of size distributions from 6000 to 24000.
 
LISST-100/LISST-ST 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. 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 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. 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 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-100X/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.
 
Replacement Large volume test chamber
Replacement large chamber that is provided standard with the LISST-100 and LISST-25. 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.

 
Custom Optical paths
Custom optical paths are available for both the LISST-100X and LISST-25X. Custom paths that have been done includes 25mm, 10mm, 5mm, 3mm, and 1mm.
LISST-WING
Sequoia announces the availability of the airborne cloud droplet sensor based on laser diffraction technology. Key features: a large swept volume (90 l/s at 60 knots airspeed), no need for velocity data, and up to 16Hz recording of the size distribution. For more information, contact us.
