The JOFRA CTC series of dry-block calibrators has
been designed for much easier true temperature
calibration in the field, leading to reliable results.
The simple operation and the automatic functions have
been carefully selected for ease of use. This has
resulted in a fast, simple and efficient temperature
calibrator without compromising quality. Reach 320°C /
608°F in just 4 minutes....

Six
models - The JOFRA CTC series consists of six
different models which differ in temperature range and
immersion depth. All units offer similar features and
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 CTC series of dry-blocks.
Well - optimized for speed - The special designed
heating block profile reduces the mass so it heats up
and cools down very quickly. The design still offers
good stability and accuracy.
High flexibility - You are not limited by fixed
holes. 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.

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. |

RS-232 and
calibration software |
| |
|
|
|
|
Simplified
calibration documentation - All CTC series
calibrators are delivered with an RS-232 serial
interface and the AMECAL-LIGHT calibration software.
This WINDOWS®-based software helps the user to
automate calibration routines and document
calibrations. The software is easy-to-use so you do not
have to be a programmer to configure your own
calibration procedures.
