Ametek Jofra ETC-125A Dry Block Temperature Calibrator

The Ametek ETC could be the world's fastest Dry Block Calibrator!

      The Ametek Jofra ETC Dry Block heats up by up to 100°C / 212°F
per minute and completes a full dual-point test in less than 10 minutes,
including stability time; timesavings at your fingertips! The ETC- series is
designed for field testing of temperature measurement devices. The small
size and light weight make it a perfect instrument to verify sensors in difficult
to reach places. All JOFRA ETC units have many of the same useful
and timesaving features offered in the more advanced JOFRA
dry-block series.


Designed for people

who perform tests and verifi cations of temperature
sensing devices in the fi eld. This instrument is ideal when time is a critical
factor and the highest accuracy is not a critical factor.

Reduced size and weight
are important considerations because the unit is able to fi t into a tool box or
instrument carrying case and can be used for sensors that are difficult to access.

One-key-one-function user interface
provides immediate access to setting
the temperature and the auto-step timesaving function. There is no need for
manipulation of sophisticated menus. 

 The Stability indicator provides
 audible and visual prompts when
 the temperature is stable. This
 function  also includes a 3 minute
 countdown before the stable

Stainless steel
and rubber side panels make the instrument suitable for many
years of faithful duty in an industrial environment.


Cooling and heating - ETC-125 A dry-block -

The ETC-125 A is a
simple yet effective tool for verifying temperature instruments that
also require references below ambient temperatures: e.g.
air-conditioning and cold counters. The predrilled holes allow the
use of an insertion tube in the largest bore. This increases the flexibility
to match many sensor-under-test sizes.




Easy-to-use, intuitive operation - All instrument controls are
accessed directly from the front panel. The main functions on the
ETC- series are designed with one-key-one-function logic. This
means that there are no difficult multiple keystrokes to remember
to access primary functions. The easy-to-read, backlit display features
dedicated icons, which help in identifying instrument conditions and
operational steps.

Set temperature -

The Up and Down arrow keys allow the user
to set the exact temperature desired with a resolution of 0.1°C or °F.

Stability indicator -
The bold checkmark on the display indicates
that the calibrator has reached the desired set temperature and is stable.
The operator may change the stability criteria and establish a greater
level of confidence in the calibration results as desired. A convenient
countdown timer is activated three minutes before the unit reaches stability.
This prompts you to be prepared to record results.


Auto-stepping -
This feature saves time. The operator may stay in
the control room, or another remote location, monitoring the output
from the sensor-under-test while the ETC- series calibrator is
placed in the process and automatically changes the temperature
using a programmed step value and rate. Up to 9 different temperature
steps may be programmed, including the hold time for each step. 
This feature is also ideal for burning-in new sensors prior to installation;
this minimizes initial drift and allows for initial testing. It is also useful for
testing temperature data loggers.


Maximum temperature -

From the setup menu, you can select a
lower maximum tempe-rature limit for the calibrator. This function
prevents damage to the sensor-under-test caused by the application of
excessive temperatures.




Instrument setups - The ETC-series stores the complete instrument
setup, including: engineering units, stability criteria, resolu-tion, auto-step
settings, and maximum temperature.




Re-calibration/adjustments made easy - The ETC- series has a very
easy and straightforward procedure for re-calibration/adjustment. There is
no need for a screwdriver or PC software. The only thing you need is a
reliable reference thermometer.
Place the probe in the calibrator
and follow the instructions on the display.

Simplified calibration documentation
All JOFRA ETC- instruments
are supplied with RS232 computer interface and the calibration software
AMECAL-LIGHT for on-line use. This WINDOWS
-based software allows
the user to customize his or her calibration routines. The software is easy
to use so you do not have to be a programmer to configure your own
calibration procedures. After calibration you can print out certificates
that contain all necessary information for your ISO-9000 or similar
quality systems.
The ETC calibrator can also work with the larger
AMECAL-TEM-PERATURE software, which supports automatic calibration
for all JOFRA dry-block calibrators equipped with an RS-232 serial data
interface including the JOFRA DTI-1000 digital thermome-ter. For
semi-automatic calibrations, the software also supports liquid baths, ice points,
or other dry-block heating and cooling sources. Using the software's
»SCENARIO« function allows for combining instruments in virtually
any configuration.
