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.

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. More
about Dual-zone central-control
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.
Time saving
features
Switch
test - Fully automatic test of thermo switches. The
calibrator will find the closing and the opening
temperatures and calculate the hysteresis. This 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.
Correct and
safe calibration
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. More
about MVI
Stability
indicator - Clear audio and visual indication in the
display when the calibrator is stable.
RS-232 and
calibration software option
Simplified
calibration documentation - As an option, all CTC
series calibrators can be delivered with an RS-232
serial interface and the AMECAL-TEMPERATURE software.
This WINDOWS®-based software allows the user to
customize calibration routines. The software is easy to
use so you do not have to be a programmer to configure
your own calibration procedures . More
