A live, highly flexible and cost effective condition based monitoring solution. Designed to be permanently mounted within any lubrication system and on any type of machine.

Over 60 times more sensitive to oil contamination that any other dielectric constant measuring sensor, the Tan Delta Oil Quality Sensor (OQSx) provides real-time monitoring of water ingress and oxidation levels.

Designed and developed to the highest standards, delivering accurate real time monitoring of the condition of any lubricating oil. Based on a patented method, the Oil Quality Sensor (OQSx) gives you a true 360 degree view of how your oil is performing.

The OQSx-G2 is the world’s most advanced and flexible real-time oil quality/condition monitoring sensor. Suitable for application in any commercial or industrial environment from the smallest genset, to the largest engines on ships and mining equipment.

Easy to install, the OQSx-G2 continually analyses oil in real-time whilst equipment is in operation and provides an accurate statement of oil condition. Any wear or contamination is instantly detected, measured to an accuracy of 0.01%, and reported.


• FULL SPECTRUM HOLISTIC (FSH™) Detects all and any wear and contamination: water, acid, fuel, viscosity, different oil types, carbon, particles etc. • ABSOLUTE ACCURACY The FSH technology within our sensor enables it to have a oil quality change sensitivity detection of 0.01% (10ppm) with an accuracy margin of +/-0.5%. • REAL-TIME Continuously analyses oil condition on operating equipment and reports oil condition every two seconds. • ROBUST & RELIABLE Proven around the world for use in even the most extreme industrial and commercial applications. • EASY TO INSTALL Quick and easy to install on any equipment with plug & play integration with any existing data reporting and display systems.


Every equipment operator knows that machine monitoring enables effective management and thus increased reliability, efficiencies and profits. Oil condition monitoring with Tan Delta takes this to a new level through much greater insight into the real condition of your equipment, delivering significantly enhanced financial and operating benefits. • REDUCE MAINTENANCE COSTS Eliminate unnecessary maintenance and equipment downtime by precisely identifying oil end-of-life and reliably predicting optimal maintenance schedules. • REDUCE BREAKDOWNS & DAMAGE Improve efficiency and extend the life of your equipment by ensuring optimal oil condition and reliable early detection of potential issues before wear particles are present and damage has already occurred. • REDUCE OIL SAMPLING Significantly reduce time consuming oil sampling and costly laboratory analysis.
