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.
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. More about MVI
Stability indicator - Clear audio and visual
indication in the display when the calibrator is stable.
Simplified calibration documentation - All JOFRA CTC
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.
