What POLARIS Laboratories^® Customers Say:

The partnership with POLARIS has been one of trust. Arch’s trust in POLARIS’s strong work ethic, unbeatable customer service, genuine care for our assets as if they are theirs and quick and accurate delivery of oil analysis reports.

Joe SwanArch Resources

In a tight schedule, we have to perform and if you can not perform, the whole schedule of our client goes down the drain. So we really have to perform when the time is there and oil analysis is one of the items that helps us maintain our fleet the best we can.

Hermen KampMammoet

The biggest thing is how much lube analysis strengthens our message … we tell a story that we’re going to give them the whole package that include the lube analysis, help them read it, interprets the results and that really strengthens the message.

Dennis MungleCountryMark

The sampling is critical to understanding how your engines are operating. It gives you that live data to tell you exactly what the content of that oil is. And with our company we run a variety of equipment… we have to be able to adjust our intervals and constantly monitor these engines to optimize the performance and reliability based on the results.

Matt CopotTranservice Logistics

When fluid analysis starts to really give you diagnostic information, prevents failures, reduces call outs and improves uptime it’s a win-win for everybody.
