The fluid sampling kit is a complete solution for field-based fluid collection and contamination analysis. The stainless steel sampler assembly plugs into a quick-release valve installed in the system line, which allows a measured quantity of liquid to pass through the monitor. A valved syringe serves as a pump to remove residual liquid from the monitor. Kit is compatible with our 37 mm contamination monitors and matched-weight monitors.

A slight change in temperature usually has a big impact on the conductivity value of a standard solution. A table on every bottle label indicates the conductivity values at the most common measurement temperatures.
During calibration the meter automatically references to this table for temperature compensation. If possible, calibration and measurements should be performed at the same temperature
