Dry-block temperature calibrators
Ametek Calibration'sr ange of Jofra ATC dry-block temperature calibrators covering the temperature range from -90degC to 650degC offer improved accuracy and stability compared to earlier versions.
Ametek Calibration Instruments has announced that its range of Jofra ATC dry-block temperature calibrators covering the temperature range from -90degC to 650degC, now offer improved accuracy and stability Accuracies for both A and B models across the range using the built- in internal reference sensor have been improved

Multi-scanner calibrates sensor groups
Advanced Signal Multi-scanner at MTEC 2006 provides an automatic solution for the calibration of up to eight temperature sensors, or three stacked manage up to 24 sensors.
Specifications for individual models can be found on-line, but as an example, the accuracy for the ATC-156 has improved from + 0.19degC to + 0.1degC.
For ATC B models accuracies down to +/-0.04degC is obtainable, when using the reference input.
Temperature stability has also been improved on the ATC-156, ATC-157, ATC-320 and ATC-650 models and is now guaranteed for a full twelve- month period, for customer peace of mind.
For most models the stability has been improved from + 0.02degC to + 0.01degC.
The units also feature a temperature stability countdown timer which starts five minutes before the stability indicator comes on.
This helps the user to know when to take readings from the sensor-under-test.
Jofra ATC dry-block calibrators are characterized by the unique dual zone heating technology for exceptional temperature homogeneity.
All Jofra dry block calibrators are supplied with Jofracal temperature calibration software, which features comprehensive documenting software to allow the creation of complete calibration work orders, which can be downloaded to the ATC series.
These can then be run on site with no need for a computer, and the results uploaded at a later date.
A complete database and certificate printout capability facilitates paperwork generation, even providing for local language translation on certificate printouts.
'B' versions of models in the ATC range feature comprehensive sensor- under-test inputs.
These include inputs for testing thermo switches, 4-20 mA transmitters, thermocouples (including cold junction compensation) and multiple types of RTD including Pt100.
An external reference probe input allows the probe to be positioned next to the sensor-under-test within the insert.
