Isocal-6 Series
Europa-6, Venus 2140, Calisto 2250
The Isocal-6® series offers an exceptionally wide operating range in an easy to use portable package. As discussed
previously the Isocal-6 series can be used as a Dry Block, a Liquid Bath, a Blackbody Source for infrared thermometers,
a Surface Sensor Calibrator and for performance to a few mK (0.001°C) ITS-90 Fixed Points. Isocal-6 calibrators are
available in two models, BASIC and SITE. The BASIC model includes a sophisticated temperature controller with a
dual display to show the desired Set Temperature and the actual Dry Block Temperature. The SITE model additionally
includes a digital indicator to which an external temperature sensor can be connected providing an accuracy of
±0.1°C.
For Dry Block use the unit under test may be compared to the controller value, Isotech recommends the use of an
external reference probe connected to the indicator of the SITE model which compensates for the temperature gradient
and loading errors. This gives greater accuracy and traceability meeting the requirements of ISO 9000 and other quality
standards.
For the best measurement results with liquid bath, surface sensor and blackbody configurations, an external standard
probe should always be used, either with the SITE models’ indicator or a laboratory performance temperature indicator
such as one of the Isotech True Temperature Indicators (TTI).
All Isocal-6 calibrators include as standard: Cal Notepad Windows Software, Serial Computer Interface,
Ramp-to-Set-Point Feature. Increased resolution of ±0.01 available throughout the range via the PC
interface and from -19.99 to +99.99 locally on the auto-ranging front display. The controller features
multi-point block to display correction giving excellent absolute accuracy.
The SITE model indicator has a universal sensor input allowing Platinum Resistance Thermometers,
Thermocouples (Types K, N, R, S, L, B, PL2, T, J and E) along with Linear Process Inputs including
4-20mA current transmitters to be displayed. The indicator can be programmed with up to five
calibration points to provide high accuracy digital probe matching. The indicator and controller are
both addressable over the communications link.

Calibration and Uncertainty
A certificate, traceable to NIST, is included as standard.
The accuracy will depend very much on the mode of use
and the types of sensor to be used. Please contact Isotech
for tutorials and uncertainty calculations and comprehensive
evaluation reports. The Isocal-6 meets the Calibration Capacity
requirements of EA I0/13, “EA Guidelines on the Calibration of
Temperature Block Calibrators”.

Introduction to the Isocal-6 Calibration System
What is Isocal-6?
The Isocal-6 is a flexible range of calibration systems that can
calibrate all types of temperature sensors and share common
features.
What is special about the Isocal-6 range?
Previously temperature calibration baths were specified by type,
for example, Dry Block Bath, Liquid Bath, Blackbody, Fixed-Point
Apparatus, etc.
Each different calibrator type has unique advantages over another,
for example, Portable Stirred Liquid Baths have a large well which
is filled with liquid. The temperature sensors are placed directly into
the liquid avoiding the need for specially drilled blocks. They are
ideal for awkward shaped and short sensors. Angled probes will not
readily fit into a metal block but can be placed into the liquid.
Accuracies are in general better than dry blocks due to lack of air
gaps and the temperature uniformity of the stirred liquid.
If a laboratory standard temperature indicator is added much
greater accuracies than those from Dry Blocks alone can be
achieved, due to better axial and radial uniformity and with
suitable reference thermometers performance of up to 0.005°C
is achievable.
However dryblocks typically heat and cool much faster, are less
messy and more portable. For more information on Dryblocks
refer to our dedicated section on page 73.
With the Isocal-6 different inserts are added to the bath to allow
it to be used in 6 different modes providing a solution for all
temperature sensor calibration requirements.
INDUSTRIAL
What are these different modes?
The Isocal-6 includes a removable metal insert as standard for use
as a Dry Block Calibrator, with optional accessories the Isocal-6
can perform as:
A Stirred Liquid Bath
A Stirred Ice Bath 0°C Reference (Cooling models only)
A Blackbody Source for IR thermometers
A Calibrator for Surface Sensors
An ITS-90 Fixed Point Apparatus
What if only one option is required?
The advantage of the Isocal-6 is that you need only purchase the
main apparatus initially, and add other accessories at any time, to
increase your accuracy, stability and overall capability.
What temperature range is covered?
Different models cover the temperature range from -45°C to
250°C, above this maximum temperature it is not practical to use
a stirred liquid bath. For higher temperatures see the other Dry
Block Calibrators that go to 1200°C, many with accessories for
Surface Sensor and Blackbody use.
The Isocal-6 range is divided into two groups. The first group,
including the Europa, Venus and Calisto models are supplied
standard in the Dry Block configuration and have a large 35mm
x 160mm calibration volume. The second group includes the
Hyperion and Drago which are supplied standard in the liquid
bath configuration and have a larger calibration volume of 65mm
x 190mm for ultimate performance and versatility. Each group has
all the Isocal-6 accessories available to it.
What performance can be achieved?
This varies on the way it is used, for an ITS-90 fixed point apparatus
uncertainties of better than 0.001°C can be achieved — see the
uncertainty graphs for other modes of operation.
Local support?
Isotech has an extensive network of authorized representatives
throughout North America who are skilled in temperature
metrology and eager to provide both before and after sales
support.
Made to last?
All Isotech products are engineered for long life. If you have
ever tried to get inside the dashboard of a motor car you will
appreciate that cheapness goes with inaccessibility for repair and
maintenance. Isotech’s products are designed for long life, easy
repair, accessibility and maintenance.
The ISOCAL-6 is currently subject to a patent application
(reference 9900158.8).
