E-IDOS — Oil Health Intelligence
Know your hydraulic and lubrication oil health continuously — particle contamination, water saturation, and flow — logged to ISO/NAS cleanliness standards. The controller is Elpis; the contamination sensor stays your choice. A standalone on-site instrument today, with EREMOS V2 streaming on the roadmap.
ISO 4406 / NAS 1638 cleanliness · particle contamination · water saturation · oil flow · sensor-agnostic · on-site HMI + printed report + BLE app · standalone today, EREMOS V2 streaming on the roadmap.
Know the oil before damage becomes downtime.
E-IDOS is a rugged appliance for hydraulic and lubrication oil condition monitoring. It continuously measures oil health — solid particle contamination, water saturation, and oil flow — in both online and offline states, and logs results to ISO 4406 / NAS 1638 cleanliness standards. The result is early warning on the fluid condition that quietly damages pumps, valves, bearings, and seals, instead of a quarterly lab report that arrives too late to act on.
It is part of the Condition Monitoring pillar — see the capability story → /capabilities/condition-monitoring. Today E-IDOS is a standalone reliability instrument — it auto-emails reports, prints an ISO 4406 / NAS 1638-coded report on-site via a built-in thermal printer, and exposes data through a BLE Android app. Streaming into EREMOS V2 (alarms, dashboards, incident workflows) is on the near-term roadmap — until it ships, E-IDOS delivers its value as a standalone instrument. (See → /eremos-v2 for the platform it will stream into.)
What it does — and what it replaces.
Measures oil health continuously
Solid particle contamination, water saturation, and oil flow — online and offline — instead of a periodic grab-sample.
Logs to ISO/NAS cleanliness standards
ISO 4406 / NAS 1638 cleanliness codes, trended over time — the language a reliability program already speaks.
Sensor-agnostic by design
The Elpis Sensor/HMI Controller is ours; the contamination sensor is your choice — supported vendors include HYDAC, Parker, MP Filter, and Argo-Hytos.
Reports on-site, today
Built-in touch HMI, a 58 mm thermal printer for an on-the-spot ISO 4406 / NAS 1638-coded report, and a BLE Android app — no platform dependency to get a diagnostic in hand.
E-IDOS removes from the customer BOM:
- a separate oil-contamination laboratory contract;
- manual oil-sample collection and shipping;
- a standalone oil-condition monitor;
- a third-party fluid-analysis vendor relationship;
- service-interval guesswork on hydraulic and lubrication systems.

The instrument in the stack — today, and on the roadmap.
The diagram shows two states honestly: the customer's contamination sensor (sensor-agnostic) feeds the Elpis Sensor/HMI Controller, which produces a complete on-site diagnostic today — touch HMI, thermal-printed ISO 4406 / NAS 1638-coded report, auto-email, and BLE Android app — without any platform connection. Streaming alarms / dashboards / incident workflows into EREMOS V2 is near-term roadmap, drawn dashed. The form factor is designed for an AMC provider to measure on-site and hand over a documented report.
Start with the hydraulic system you can't afford to lose.
Packaging labels are illustrative until commercial packaging is approved; this section describes how to engage + what it pairs with, not pricing.
E-IDOS engagements start with a specific hydraulic or lubrication system — and the oil that quietly decides its life. It's scoped against the oil type, the contamination sensor, online vs. offline measurement, the ISO/NAS targets, and the reporting workflow. For AMC providers, the built-in HMI, thermal printer, and BLE app are the point: go to a customer site, run a measurement, hand over a printed ISO 4406 / NAS 1638-coded report, and walk away with a documented diagnostic — no platform dependency. For in-house maintenance, it replaces lab turnaround and service-interval guesswork with on-site oil-health intelligence. Bring the system, the oil, and your cleanliness targets; we'll scope the sensor + reporting. Contact Elpis for availability and scoping; detailed pricing follows the scope. No pricing tables, SKU grids, or per-unit pricing on this page.
Built for the field, and for the service visit.
Built for the field, and for the service visit.
A rugged appliance with on-site touch HMI, thermal-printed reports, and a BLE app — a complete diagnostic in hand without a platform connection. Sensor-agnostic on the contamination input; the controller is Elpis. IP65 / IP67-compatible configuration confirmed during BOM scope.
Where it's deployed.
Deployed in defense and space-agency programs — ministry-tier fluid-condition deployments (via third-party supplier integration).
Maintenance and AMC providers across India and the Middle East use E-IDOS to deliver their own oil-health services.
Operating across India and the Middle East.
Formal third-party certifications are not currently claimed. Certification, ingress-protection, and site-compliance requirements are handled case-by-case during BOM scope; IP65 / IP67-compatible configurations can be scoped where required, but certified/rated claims are published only when formal evidence exists. Specific customer names and case studies arrive with the Phase 3 customer-story program; the category descriptors above are the standing, authorized proof.
What maintenance managers ask.
What does E-IDOS measure?
Hydraulic and lubrication oil health — solid particle contamination, water saturation, and oil flow — online and offline, logged to ISO 4406 / NAS 1638 cleanliness standards. Measurement ranges and oil compatibility depend on the selected sensor and are confirmed during BOM scope.
Which contamination sensors does it work with?
E-IDOS is sensor-agnostic on the contamination input: the Elpis Sensor/HMI Controller does the conditioning and ISO/NAS analytics, and the contamination sensor is your choice — supported vendors include HYDAC, Parker, MP Filter, and Argo-Hytos (and similar). The controller is Elpis; the sensor choice is yours — which matters if you have existing sensor inventory or supplier relationships.
Does it stream into EREMOS V2?
Not today. E-IDOS is a standalone instrument today — it auto-emails reports, prints an ISO 4406 / NAS 1638-coded report on-site via the built-in thermal printer, and exposes data via a BLE Android app. Streaming into EREMOS V2 (alarms, dashboards, incident workflows) is on the near-term roadmap. Until it ships, E-IDOS delivers its value as a standalone instrument; we'll be explicit about what's available at scope time.
We're an AMC provider — how does E-IDOS fit our service?
It's built for exactly that. The touch HMI, 58 mm thermal printer, and BLE app let you go to a customer site, run a measurement, and hand over a printed ISO 4406 / NAS 1638-coded cleanliness report — a documented diagnostic, on the spot, with no platform dependency. Maintenance and AMC providers across India and the Middle East use E-IDOS to deliver their own oil-health services.
Online or offline — how does it measure?
Both. It measures inline on the hydraulic / lubrication circuit (online) and in offline states. Which mode, and the hydraulic connection / sampling point, are confirmed during BOM scope against your system.
Does it prevent breakdowns?
It gives you early warning: catching rising particle contamination or water saturation early enough to investigate, filter, flush, or service the system — before the fluid condition damages pumps, valves, bearings, and seals. It does not guarantee against every failure; it replaces lab-turnaround delay and service-interval guesswork with on-site, trended oil-health evidence.
Is it certified? What about IP65 / IP67?
No formal third-party certifications are currently claimed. Certification, ingress-protection, and site-compliance requirements are handled case-by-case during BOM scope. Where the placement requires IP65 / IP67-compatible protection, Elpis can scope a compatible configuration or enclosure approach; formal certification or rating claims are published only when the specific product/configuration has the required certification or test evidence.
How is E-IDOS different from VAS?
Both are Condition Monitoring instruments for the maintenance buyer, but they watch different failure evidence. E-IDOS is oil / fluid health on hydraulic and lubrication systems (contamination, water, flow; ISO/NAS) — a standalone instrument today, EREMOS V2 streaming on the roadmap. VAS is vibration on rotating machinery (bearings, imbalance, misalignment) — and feeds EREMOS V2 today. See VAS for rotating machinery.
Looking at this from another angle?
Bring us the hydraulic system you can't afford to lose.
The system, the oil it runs on, and your cleanliness targets — that's what we scope an E-IDOS deployment against. We'll match the sensor, set the ISO/NAS targets, and put a documented oil-health diagnostic in your hand on-site.
