Ellab Temperature Indicator

ETI - Recorder Plus

The ETI Recorder Plus is a high quality digital temperature and pressure-indicating device designed for displaying and documenting the processing temperature and pressure in retorts. It complies with FDA 21 CFR Part 113, and it is ideal for thermal processing of low-acid canned foods. The ETI Recorder Plus has a digital display that is easy to read, offers an temperature accuracy of +/- 0.1°C and an pressure accuracy of 0.15% full scale (20…120 °C), and does not constitute a potential source of mercury contamination.

Compliant with FDA 21 CFR Part 113

  • FDA compliant alternative to mercury-in-glass thermometers
  • Dual interchangeable sensor
  • Pressure sensor option
  • Interchangeable sensors
  • NIST traceable (or equivalent) calibration certificate
  • In-house calibration with full documentation
  • Remote display option (1,200 m / 3,900 ft.)
  • Rechargeable backup battery

Documented and Traceable Accuracy

The ETI Recorder Plus has an accuracy of +/- 0.1°C / 0.18°F and is tested against an accurate calibrated reference device and is delivered with a NIST traceable (or equivalent) calibration certificate. The ETI Recorder Plus temperature sensor has a unique ID which is shown on the calibration certificate ensuring traceability.

The combination of full compliance with FDA regulations and Ellab’s renowned quality and high reliability makes the ETI Recorder Plus an excellent choice for retort monitoring. Recognizing that product safety, quality and efficiency are critical to our clients, Ellab has added additional features to the ETI Recorder Plus.

The factory recalibration procedure is made simple as the sensor holds both calibration constants and ID which are independent from the display. When sending the sensor in for factory calibration, a certificate will be issued which includes all of the information needed to comply with FDA regulations and ensures the reliability and accuracy of the ETI. The calibration date is easily visible on the digital display. The ETI Recorder Plus display automatically shows a warning 28 days before factory recalibration is due.

Data Transfer and Alarming

The ETI Recorder Plus offers complete process control and monitoring via optional connection to a PLC using Modbus communication.

The temperature, pressure and time measurements are communicated directly to the PLC. This makes it possible for the user to control the process and the machine (autoclave). Monitoring one or several ETI Recorder Plus units is possible when the PLC is connected to a SCADA system. This ensures an accurate overview of the measurements from all ETI Recorder Plus units installed.


  • ETI to PLC communication
  • PLC controls the process
  • Monitoring of several ETI units in one place
