Your
choice for optimum temperature calibration
|
|
|
The JOFRA ATC series (Advanced Temperature Calibrators) combines
the accuracy of
|
|
|
laboratory temperature
sources with the speed and portability of field dry-block calibrators.
|
|
|
|
|
|
With
the latest ATC models it is now possible to calibrate even more sensors at
the same time
|
|
|
and to calibrate large and odd size sensors in
either a large diameter dry-block or in a liquid bath.
|
|
|
|
|
|
PRODUCT DESCRIPTION
|
|
|
The ATC series calibrators are available in six different
temperature ranges with two models offered
|
|
|
in each range; A and B.
|
|
|
|
|
|
All
JOFRA ATC series modes feature the unique dual-zone heating block- designed
for optimum
|
|
|
performance and superior
temperature homogeneity throughout the block. This new design has
|
|
|
a performance equivalent to a liquid temperature
bath. The ATC-157 features the widest
|
|
|
temperature range for a cooling
dry-block on the market today.
|
|
|
|
|
|
Each ATC dry-block calibrator may be used to perform fully
automatic calibration routines without
|
|
|
using an external
computer. Use the computer for full upload and download capabilities. Units
may
|
|
|
also be supplied
with inputs for external reference sensors and for sensors-under-test. All
ATC
|
|
|
calibrators feature RS232 serial communication and standard
delivery also includes the JOFRACAL
|
|
|
calibration PC
software.

Liquid bath or dry-block
|
|
|
Use ATC-140 and ATC-250 as liquid bath or large diameter
dry-block calibrator
|
|
|
Improved
temperature homogeneity
|
|
|
Unique
dual-zone block ensures good temperature homogeneity in the critical
calibration zone
|
|
|
High accuracy
|
|
|
Using the internal reference or the
external reference probe. 4-wire True-Ohm-Measurement
technology is used.
|
|
Enhanced
stability
|
|
|
MVI
circuitry ensures temperature stability despite mains supply variations.
|
|
|
Cost effective calibration system
|
|
|
Stand-alone operation eliminates the need for secondary equipment
and PC. Universal inputs handle
|
|
|
multiple type
temperature sensors.
|
|
|
Timesaving
features
|
|
|
Up-
and download complete calibration tasks. Auto-stepping, switch testing and
many more features
|
|
|
make the daily use smooth and fast.
|
|
|
Documentation made easy
|
|
|
RS232 communication and JOFRACAL calibration software are
included in the standard delivery.
