Condition Monitoring analyzes the condition and components of fluids to provide insights into the suitability of the fluid for further service and the condition and efficiency of the equipment.  Base number, acidity, water, ferrous metal contaminants, silicon and other indicators provide insight into the equipment operation enabling corrections and maintenance to prevent downtime, improve efficiency and to extend equipment life.  

We have links to training documents and videos on this website.  We can also arrange for video conference seminars for specific individual or group training needs.

DSI has the capability to source many condition monitoring and related equipment from numerous suppliers.  If it is available, we will do everything in our power to meet your equipment needs.  We have built our reputation on the creation of strong relationships with both our customers and suppliers and remaining flexible to meet individual requirements.

Functional checks can be performed on most equipment in the field. We do however recommend that certain equipment (notably the electronic test equipment) is recalibrated every two years.  DSI is here to help coordinate that process. 

We can recommend and coordinate several maintenance options to suit your particular needs and budget.  From an on-demand service, stock replacements and updates to the latest specifications to a complete overhaul and calibration program.

Some of our reagents are classified under IATA (air), IMDG (sea) or IRD (road) transportation codes. DSI suppliers provide packaging that has been tested and approved for use under the regulations to transport dangerous goods at no extra charge to the customer. However, the freight costs are subject to standard dangerous goods charges and we are legally bound to declare the goods and pay this charge. Be assured that we make every effort to minimize the cost of transporting these hazardous goods.
