Wired Thermocouple System

Wired Thermocouple System

- Compact, precise and extremely efficient

The E-Val™ Pro thermocouple system is packed with features that make validating processes with cables a whole lot easier. The FDA and GAMP compliant module is the ideal solution for traditional thermal validation methods. 


E-Val™ Pro - Thermocouple System

The E-Val™ Pro thermocouple system for thermal validation is immensely easy to handle within controlled environments due to its compact size and light weight. The thermocouple system complies with FDA regulations as well and GAMP guidelines and is designed to be the ideal solution for any thermal validation process.

The secure and password protected module can handle up to 40 thermocouples and the large internal memory is capable of holding up to 10 studies at a time. The wired thermocouple system has a built-in 8-hour battery and can be used as a stand-alone unit or be connected to a PC via LAN/USB. 

The E-Val Pro is equipped with interchangeable sensor arrays, which can easily be removed for service and calibration. With 4 and 12-channel arrays available, the E-Val Pro can handle all thermocouple types as well as analog and digital inputs.

Thermocouple system with graphical display
Due to its 8’’ display and user-friendly interface with touch function, the thermocouple system is very intuitive and easy to operate. The thermocouples are equipped with USB connectors, resulting in a safe, fast and easy plug-and-play setup. The graphical display increases efficiency as the measured results are easy to read and analyze on the spot. The easy expandability with various parameter and sensor options, makes the E-Val Pro thermocouple system a complete validation solution for any facility with a wide variety of applications.

High accuracy thermocouples with cold junction compensation
All Ellab type T thermocouples have a built-in cold junction compensation in the USB connector. A Pt1000 element in each individual thermocouple, ensures a high accuracy leading to a more stable and accurate validation process.

Validation Software with numerous reporting options
The thermocouple system also utilizes the FDA 21 CFR Part 11 compliant ValSuite® Pro validation software, which keeps a complete database of all aspects of your validation requirements - tracking thermocouples, calibration reports, test setup, data analysis, specific user access and final compliance reports. The software even allows validators to combine wireless data loggers and thermocouples in the same study.

Thermocouple Sensors

Interchangeable sensor arrays are supplied and each can accommodate up to 12 thermocouple or analog/digital inputs. Thermocouples can be organized into groups for real time statistical analysis.

The traceable and interchangeable thermocouples comprise of a smart USB connector that is molded and sealed. Built-in cold junction compensation is integrated into each USB connector. Each connector maintains the calibration offsets reducing the pre and post calibration time and efforts.

Other Measuring Parameters for E-Val™ Pro

Unlike most classical thermocouple systems, the E-Val™ Pro has the option of measuring several different parameters other than just temperature. To do this, Ellab designed a Sensor Interface which can be fitted with any sensor, thereby covering all available measuring parameters. These sensors are the same ones used in combination with the TrackSense® Pro series of data loggers.

Measuring Parameters:

  • Temperature
  • Pressure
  • Vacuum
  • Relative Humidity
  • Conductivity
  • CO2
