S02: 0.2 - 2.0 µm, S03: 0.3 - 3.0 µm, S05: 0.5 - 20.0 µm

LiQuilaz® II optical liquid particle counters are volumetric monitors with a variety of sizing sensitivities as low as 0.2 µm. They provide high precision analysis for most process chemicals, including hydrofluoric acid and hot corrosive chemicals up to 306 °F (152 °C).

LiQuilaz II sensors provide the same levels of accuracy, reliability and repeatability that customers have trusted for many years. LiQuilaz II sensors feature both RS-485 and Ethernet network communications. The new Ethernet capability increases product flexibility and makes installation significantly easier.

Volumetric particle counters offer the highest precision possible by measuring 100% sample volumes (up to 80 ml/min) so that short sampling intervals can be utilized without sacrificing statistical significance.

Liquid Installation Kit

Liquid Installation Kit

For use with online  applications, the Liquid Installation Kit includes: a Flaretek® flaring tool, five caps, 25 ft of 1/4 in Perfluoroalkoxy alkanes (PFA) tubing and male connectors.

Capillary Cleaning Kit

Capillary Cleaning Kit

The Capillary Cleaning Kit flushes capillaries with a Flaretek® adapter and contains: two 10cc syringes and two Flaretek® tube fittings.

Communication Accessories

Communication Accessories

The LiQuilaz Particle Counter communicates via RS-485 protocol, so communication accessories are required.Depending on the configuration, you may need two cables and a BB485 converter. If the LiQuilaz instruments are daisy-chained (i.e. connected in series), a standard nine-pin serial cable can connect the two instruments.If the computer does not have a nine-pin serial port, a USB-to-serial converter is also required.
