Sampling Station

The Metso Sampling Station is a ventilated cabinet where process liquids can be sampled in a safe manner. Sampling of liquids in metallurgical process plants serve many purposes, such as improving the understanding of the operation, assisting with troubleshooting and optimizing the operation.

Generally, liquids in metallurgical process plants contain many hazardous substances, and sampling them constitutes a risk. The Metso Sampling Station is developed to reduce this risk, making sampling and maintenance of specific instruments more convenient.

Sampling process

The operator ensures the ventilation in the cabinet is functioning
The sample is taken according to the type of sampling valve used
Sampling bottles are stored and can be cleaned in the cabinet using the installed fresh water supply
Excess liquid is disposed in the drain of the cabinet.

Instruments that require frequent cleaning and calibration can also conveniently be positioned in the sampling station, facilitating maintenance and reducing the risk for exposure to personnel.
