Trusted process records for temperature-driven industries
Capturing, displaying, and recording accurate, time-stamped process data to support process run review, audit readiness, and regulatory compliance across metals, heat treat, life sciences, and other temperature-critical industries
Designed for Trusted Process Records
EPM Data combines instrument-grade measurement, modular hardware, and purpose-built software to create a reliable, time-aligned process record for temperature-driven operations.

Built-in audit trail for trusted records
All configuration changes and user actions are automatically logged, creating a consistent, reviewable audit trail that supports regulated and quality-critical environments.
Intuitive, touch-based configuration
On-screen configuration enables fast setup of I/O, channels, and recording parameters without external software. Multi-touch interaction and responsive UI simplify daily operation and reduce training time.Industrial-grade, serviceable design
Field-replaceable HMI and I/O modules reduce downtime and simplify maintenance in demanding industrial environments.
Flexible Display Options
Multiple screen sizes support different panel layouts and operator needs, from compact installations to wide-format displays for improved visibility.
Instrument-grade precision inputs
Patented EPM I/O architecture exceeds stringent accuracy requirements for critical thermal data, supporting standards such as SAE AMS2750 and other accuracy-driven applications.
Native I/O expansion
Integrated expansion I/O increases channel count without external hardware, reducing wiring complexity, engineering effort, and overall system cost.
Secure, segmented networking
Multiple Ethernet ports support separation of IT and OT networks, enabling secure data exchange while aligning with industrial cybersecurity best practices.
Remote access and web-based viewing
An embedded HTML5 web server allows secure remote access from standard browsers, supporting review and monitoring from PCs, tablets, and other web-enabled devices.
Designed for legacy panel cut-outs
Form factor supports drop-in replacement of existing paper and digital chart recorders, minimizing panel modification and retrofit effort.
Navigating the Evolution of Process Data and Compliance
As temperature-driven processes become more complex and regulated, teams need process data that supports daily operations, confident decision-making, and audit readiness without added system complexity.
Rising expectations for data integrity
Accurate decisions depend on confidence that recorded data reflects what was actually measured. Small errors in measurement, timing, or configuration can undermine trust during process run review and audits.
Increasing audit and regulatory scrutiny
Industries face growing expectations to demonstrate control, traceability, and data integrity across customer, industry, and regulatory standards, often using the same process records over long retention periods.
Operational pressure to move beyond legacy recorders
Paper and legacy digital chart recorders are being replaced by systems that support faster review, easier troubleshooting, and consistent records without manual reconciliation or rework.
One record supporting multiple workflows
The same process data must support operators, engineers, quality teams, and auditors at different points in time without changing meaning or interpretation.

Flexible System Architecture
EPM Data is designed to fit naturally into existing industrial environments, supporting secure data flow from the field to enterprise systems and, where required, to the cloud. Measurement and recording occur at the edge, while review, configuration, and analytics can be performed locally or centrally without disrupting operations.
At the field level, EPM devices capture and display real-time process data while creating a reliable, time-stamped record. Data can be reviewed locally or shared over a segregated field Ethernet network. At the enterprise level, review and configuration tools provide centralized visibility and management across multiple assets. Optional gateways enable secure data transfer to cloud analytics platforms, allowing organizations to extend insight without compromising data ownership or control.
This layered architecture supports IT/OT separation, scalable deployment, and cybersecurity best practices, giving teams the flexibility to modernize at their own pace while maintaining trusted process records.

Insights & Impact
Evidence, expertise, and events driving innovation across industrial processes.
Environmental & Emissions Monitoring
Process chart recorders are used across distributed monitoring sites to capture and retain environmental process data over long periods. These systems support accurate tracking, reporting, and regulatory oversight by providing a reliable, time-stamped record of measured conditions.
Key impact: Trusted long-term data integrity for compliance and reporting.
Healthcare and Instrument Disinfection Validation
Manufacturers of medical and laboratory equipment use process chart recorders to independently verify temperature and process conditions during critical disinfection and sterilization cycles. This provides an authoritative process record used for validation, review, and traceability.
Key impact: Improved confidence in safety-critical processes and audit readiness.
Aerospace and Heat Treat Quality Accreditation
In aerospace manufacturing and heat treat operations, process chart recorders are deployed to capture independent thermal process data in support of quality accreditation and customer audits. These records are used to demonstrate compliance with industry and customer requirements and to support continuous improvement.
Key impact: Streamlined audit preparation and standards conformance.
Process Data Integrity Across Regulated Manufacturing
Across industries such as pharmaceuticals, automotive, aerospace, and food production, process chart recorders provide secure, tamper-resistant records of temperature-driven processes. These records support routine review, product release decisions, and long-term retention without reliance on reconstructed data.
Key impact: Consistent, trusted process records across the full data lifecycle.
