High Quality Digital Indication

Looking to elevate your thermal processing reliability? The Ellab Temperature Indicator (ETI) delivers unmatched precision and seamless integration for modern autoclave and retort monitoring operations.

With ±0.1 °C accuracy, FDA-compliant performance, and intuitive digital readouts, the ETI ensures process control without compromise. Its interchangeable Pt1000 RTD probes allow for non-stop calibration cycles—keeping your operation efficient and compliant.

Key Advantages:

  • Plug-and-play RS-485/Modbus integration for PLC systems
  • Simultaneous monitoring of time, temperature, and optional pressure
  • Optional remote display units for facility-wide visibility
  • Mercury-free design for a safer, greener workspace

Reliable Data Transmission and Process Security

Measurement values are transmitted in real time to external systems via the RS485 interface. This enables seamless documentation and immediate response to deviations—for enhanced process control.

  • icon Interchangeable probes minimize downtime and maintain production flow
  • icon Automatic alerts for accuracy drift or probe issues
  • icon 8-hour internal rechargeable backup battery
  • icon Horizontal probe installation supported
  • icon Generate PDF reports from logged temperature/time data
Intelligent Maintenance Management

Automatic calibration alerts and integrated battery status gauges/indicators help prevent downtime. This ensures the ETI is always ready for use and maintenance can be planned proactively.

Seamless Integration with ETISuite® Software

ETISuite® is the core software for ETI reference thermometers, providing accurate, traceable temperature logging with minimal setup. It serves as a reliable digital alternative to liquid-in-glass thermometers and maintains data integrity during power outages. The software continuously records raw data, offers basic trend visualization, statistical summaries, and generates simple FDA-compliant reports—ideal for routine monitoring. Integration with SCADA or control systems is possible via custom interfaces.

While ETISuite® covers essential logging needs, it doesn’t support advanced analysis or calibration. For detailed calibration reports and full data evaluation, ValSuite® is the preferred solution.
