AMETEK Calibration Instruments has announced that its range of JOFRA
ATC dry-block temperature calibrators covering the temperature range
from -90°C to 650°C, now offers improved accuracy and stability.
Accuracies for both A and B models across the range using the built-
in internal reference sensor have been improved. Specifications for
individual models can be found at: www.jofra.com/sw39.asp, but as an
example, the accuracy for the ATC-156 has improved from + 0.19°C to +
0.1°C. For ATC B models accuracies down to ±0.04°C 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 + 0.02°C to + 0.01°C. 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.
