Accurate and easy-to-use true

C alibrator
The JOFRA ITC series of dry-block
calibrators has been designed for
accurate true temperature calibration in
the field. The ITC series features a
modified dual-zone heating block from
the ATC series. This means much better
calibration uncertainties throughout a
broad varieties of temperature sensors.
The simple operation and the automatic
functions have been carefully selected
for ease of use. The ITC series is an
efficient temperature calibrator without
compromising quality.

Model and temperature range
ITC-155 A..........-23 to 155°C (-9 to
311°F)
ITC-320 A..........50 to 320°C (122 to
608°F)
ITC-650 A..........50 to 650°C (122 to
1202°F)
Well - optimized
for accuracy - The ITC-320 and
ITC-650 employ a modified dual-zone
principle derived from the ATC series.
This ensures good temperature
homogeneity in the calibration zone. The
ITC-320 and ITC-650 also use the same
inserts as the ATC series. This means
deep immersion depth and a diameter wide
enough to leave room for also a
reference probe or multiple sensors.

Three models -
The JOFRA ITC series consists of three
models in different temperature ranges.
All units offer excellent performance
and feature the large, backlit LCD
display panel, which is easy to read
even in well lit areas. A rugged,
slim-line, aluminium outer casing with
die-cast top and bottom protects the ITC
series of dry-blocks.
High flexibility -
Interchangeable insertion tubes are used
to match the diameter of your
sensor-under-test. Also multihole
inserts are available.
Switch test -
Fully automatic test of thermo switches.
The calibrator will find the closing and
the opening temperatures and calculate
the hysteresis. This makes you save time
and leaves you free to concentrate on
other things while the test is running.
Auto step -
The calibrator will automatically change
to the next programmed value. This
allows the calibrator to be placed
anywhere in the process while you
monitor the output from the
sensor-under-test in the control room.
Easy maintenance
- If adjustment of
the calibrator is needed, use the
built-in routine. No need for a computer
or a screwdriver. "Calibration Date" is
shown each time the instrument is
switched on.
MVI circuitry
- The MVI technology removes the
stability problem caused by an unstable
mains supply. This is very often a
problem in production environments with
large electric motors, heating elements,
etc. cycling on and off.
Stability
indicator - Clear audio and visual
indication in the display when the
calibrator is stable.
Simplified
calibration documentation - All ITC
series calibrators are delivered with an
RS232 serial interface and the JOFRACAL
calibration software.
JOFRACAL software presents the means for
an entirely automatic calibration of
sensors and a semi-automatic calibration
of the complete process loop through the
use of a PC.
