The S4031 WG is a portable particle counting system for water based liquids, mainly used for hydraulic systems in offshore oil industry. A wear resistant ceramic piston pump guarantees a constant flow. With a simple to use touch screen user interface operation is easy and intuitive. The system is equipped with a built-in battery for up to 2h operation and a data storage of more than 500 measurements. Usable for batch sampling and online measurements.

Sample input:
Low pressure: 0 to 7 bar - batch and online mode
High pressure: 3 to 420 bar - online mode

Particle sensor: HCB-LD-50/50
Max. concentration: 24.000 per ml at 7% coincidence
25 ml/min nominal flow rate
Calibration according to ISO 4406:1999 4µm(c), 6 µm (c) and 14 µm (c) based on ISO 11171 and with latex spheres for measurements according to NAS 1638.

Up to 32 free adjustable size channels can be used and 16 different channel settings may be stored in the system. 3 different channel settings for water glycol measurements are pre set in the system:
SAE AS4059A – F, 4 – 70µm(c),
>4, >6, >14, >21, >38, >100µm(c), calibration according to ISO 11171
