Mobile Oil Tester (MOT) Kit

Mobile Oil Tester (MOT) Kit

Easily analyse any oil from any equipment in seconds with the portable MOT kit, enabling maintenance crews to make fact-based decisions. Instantly and scientifically determine exactly how worn oil is, how long until it needs to be changed or refreshed, how long until equipment maintenance is needed and be alerted to unseen internal issues with equipment which could lead to an unexpected breakdown needing attention.

Simple and easy to use with no training required. Prevents wasting of good oil and ensures equipment is maintained when needed. Typically enables a significant reduction in oil use and maintenance – resulting in significant cost savings.

The kit is built around the OQS real time oil condition analysis sensor, which analyses oil at a molecular level to determine its exact condition. Results are displayed using the MOT results application which runs on any Windows based laptop or PC. Everything is included within a single portable Peli case designed for continuous use in rough industrial and commercial environments.

Technical Specifications

Mobile Oil Tester (MOT) Kit

The kit is built around the OQSx-G2 sensor and works with dedicated MOT software that runs on any Windows-based laptop, tablet, or PC. It also includes easy-to-use sample bottles for convenient testing. Users simply install the MOT application, connect it to the sensor, and collect an oil sample using the provided bottles.

        By attaching the bottle adaptor and inserting the sensor, the software guides users through simple steps, delivering accurate oil condition results within seconds.

Oil Interpreting Guide

Tan Delta technology continuously analyses oil in real time at a molecular level, accurately tracking condition changes as equipment operation causes oil to wear. Rate of change projection enables reliable optimal maintenance forecasting and safe interval increases – thus reduced costs. Contamination or equipment issues cause trend spikes which are instantly detected, enabling immediate evaluation and action as necessary to avoid unnecessary break downs and life-shortening equipment wear.

What is the Mobile Oil Tester (MOT) and what is it used for?

Mobile Oil Tester (MOT) is a portable device designed for quick, on-site oil condition analysis. It allows users to instantly assess oil degradation, contamination, and overall condition without sending samples to a laboratory.

The MOT uses Tan Delta’s proprietary dielectric analysis technology to evaluate changes in oil properties. A small oil sample is placed in the device, which then provides an immediate Oil Condition Index (OCI) reading indicating the health of the lubricant.

Key advantages include:

  • Instant oil condition results (no lab delay)
  • Portable and easy-to-use design
  • Supports preventive and predictive maintenance
  • Reduces downtime and maintenance costs
  • Ideal for spot checks and validation of sensor data

The MOT is widely used in:

  • Automotive workshops and fleet maintenance
  • Industrial machinery and hydraulics
  • Marine and heavy equipment
  • Oil sampling and inspection routines

It is especially useful for field engineers and maintenance teams.

  • MOT → Manual, portable spot testing
  • OQS → Continuous real-time monitoring
  • OQH → Contamination detection (haze/water/particles)

Together, they provide a complete approach:
Spot Check + Continuous Monitoring + Contamination Detection
