EaziVal is a Windows software package specially written to provide traceable validation of thermal processes and includes a site and machine database; thermocouple and pressure sensor calibration; data logging with trend displays and on-line reporting. The machine database, calibration results, test results and reports are stored in tamper-proof encrypted files.

EaziVal is designed for use with the Anville data loggers, it can be used immediately, no programming is required. No software license is required for installing EaziVal on your computers and copies can be downloaded free of charge from Anville website, allowing other computers to run EaziVal for additional report generation, test result archiving and analysis. 


Anville Series 825 Thermal Validation Interface

The Anville Series 825 TVI is designed for use with EaziVal SE software. Anville's thermal validation systems can be used wherever it is necessary to maintain a formal record to prove that the correct temperatures and pressures have been achieved during a critical process.

The Anville Series 825 TVI differs from the majority of data loggers by the design of the thermocouple input connection, associated thermocouple cold junction compensation and in the use of analogue input parallel processing enabling the unit to have a acquisition rate of better than once per second for all inputs. The Series 825 TVU uses individual high speed amplification and analogue to digital conversion on each input channel with conversion to engineering units (°C/°F) carried out by the internal microcontroller. Data is communicated to the computer in the correct engineering units enabling the system to have a traceable calibration certificate. The Series 825 TVI has an internal power supply to provide a 20VDC excitation voltage for the 4-20mA inputs and no separate power supply is required for a loop powered transducer.

In the Anville Series 825 TVI all cold junction compensation errors are minimised by using correctly compensated miniature type T thermocouple connectors with matching class 1 thermocouple wiring to the internal cold junction sensor. A 1/3 DIN PT100 sensor measures the cold junction temperature to an accuracy of ±0.1°C at 0°C. Design of the physical layout of the cold junction reduces any thermal scatter to a typical deviation of ±0.05°C.

The Anville Series 825 measurement range for type T thermocouples is -200°C to 300°C with a resolution of 0.01°C. Over a measurement range from -50°C to 300°C the overall system accuracy is ±0.25°C. This accuracy is maintained over an ambient operating temperature range from 0°C to 50°C and includes all errors due to thermocouple cold junction compensation, DC amplification, A/D conversion and thermocouple linearisation.

The Series 825 TVI accuracy of ±0.25°C is a worst case "out of the box" value including all system errors but excluding thermocouple sensor error.

Series 275 Thermometer

For thermocouple sensor calibration of the complete EaziVal system the actual temperature of the calibration source must be accurately known. EaziVal provides multi-point calibration at "high", "low" and "check-point" temperatures with the scale and offset values automatically calculated for each sensor. Using a Series 275 digital thermometer as the UKAS calibrated temperature reference this information can be entered into EaziVal. The calibration results are then stored for reporting.

The Series 275 is a single channel, hand held temperature measuring system consisting of a high accuracy platinum resistance sensor coupled with a high accuracy digital thermometer. The combination of sensor and thermometer is calibrated by a UKAS accredited test house at five temperatures.

  • UKAS calibration points 0°C, 100°C, 121°C, 134°C and 150°C, other points to special order.


Series 300 Temperature Calibrator

For thermocouple sensor calibration of the complete EaziVal system the temperature of the thermocouples must be maintained in a stable state. EaziVal provides multi-point calibration at 'high', 'low' and 'check-point' temperatures with the scale and offset values automatically calculated for each sensor. The Anville 300 bath has an operating range from 40°C to 325°C. The large sensor capacity of three 3mm, three 6mm and one 10mm diameter holes make the unit particularly suitable for thermocouple calibration.
