Introducing FAST-CALs

A New Range of four
Field Block
Calibrators
 FAST-CALs work
from -35°C to 650°C
in three ranges

-35°C to 140°C,
30°C to 350°C and
35° to 650°C

Why are we introducing it?
During 2004 20 experienced engineers
from many parts of the world specified
their ideal products for Industrial
Calibration
 FAST-CAL realises their top ten
requirements of…
 FAST-CAL The product range you
helped specify and design

1. Rugged
2. Light weight
3. Easy to use onsite
4. Low cost /high benefit ratio,
5. Fast response, high stability
6. Time saving features
7. Multiple sensor testing
8. Software
9. Modern design
10. Compliant with latest regulations.

Membranes?
The team told us “Whatever you do don’t
use membrane keypads. They look great
new, but after a year of being poked with
ball point pens and screwdrivers the
results have to be seen to be believed.”
 We were going to include a picture but
we might upset the competition.

Result of Input? The FAST-CALs
Fast-Cal Features:
 Rugged, hard wearing stainless steel case.
 Hygienic with no paint to chip or flake.
 No membrane keypads.
 Lightweight, approx 6 kg depending upon the model.
 Easy to use on site, we used the latest computer technology to
design the handle at the exact balance point for each Fast-Cal
model. A soft, light weight shoulder case makes transporting the
Fast-Cal effortless.
 Fast response, high stability. Isotech has put 24 years of
manufacturing and design experience into optimising the
performance of the Fast-Cal. Compare the specifications
overleaf. The thermal gradients are minimised by non-linear
heating and cooling profiles to compensate for end losses to
ambient temperature.

The Fast-Cals are so easy to use you hardly need the manual.
The High and Medium Fast-Cals incorporate a built-in Insert holder for
ultra fast changes and re-starts of calibration cycles.
The Fast-Cals (excepting the 2010) all have the same sized removable
inserts which can be drilled to your exact requirements.
Communications are fitted as standard and a number of programs are
available depending on your needs.
The Fast-Cal design is modern and complies with all the relevant
requirements and directives which are applicable.
The Fast-Cals come with a certificate traceable to National Standards.
Five point UKAS Certification is available as an alternative.
Mains power variance immunity has been standard on all Isotech dry
block calibrators since their conception. This feature resolves problems
with fluctuating power supplies which if not acknowledged causes
instability in the bath.

Secrets of Success

FAST-CAL Inserts

Software


CalNotePad: Included as standard. This permits you
to connect both an indicator and the calibration bath to
the PC. You can view data on clear configurable chart
displays, log data to file and control the calibration
bath.
I-cal: A software application that can automatically
calibrate up to 16 temperature sensors, it provides an
expandable low cost route to automatic calibration –
with I-cal Capture you can store pictures (along with
time and temperature data) to enable, for example,
dial thermometers to be calibrated automatically;
return to a set of images of the dial captured at each
calibration temperature!

Validation of Washer Disinfectors, Steam
Sterilisers, Autoclaves to HTM 2010 and HTM
2030
For accurate calibration of sensors choose the
FAST-CAL HTM 2010
In place of a removable insert it has a fixed block
Block has room for reference PRT and test
sensors
Place the probes directly in the block and gain
better accuracy

(Avoids thermal interface between insert and block)

FAST-CAL Low

Unique Advantages continued
Ambient is the most difficult temperature to
control at
 The Eurotherm controllers designed for
Isotech are “seamless”
 Ask the competition to control at ambient
and see the instabilities

16
FAST-CAL Low

Unique Advantages continued
Insensitive to ambient variations
 One competitors bath changes its
calibration by 0.8°C for a 16°C change in
ambient
 Our equivalent models changed by 0.03°C
for a 20°C ambient change!


This is important, these calibrators are for field
use
17
Accuracy here is what we mean by accuracy
For BASIC: The agreement between the
controller indication compared to a close
fitting standard located at the bottom of
the dry well insert
 For COMPLETE: The agreement
between the Indicator and a close fitting
standard located at the bottom of the dry
well insert

18
Accuracy International Standard

EA10-13 is the only published document
relating to the full performance of dry
block calibrators

http://www.european-accreditation.org/
FAST-CAL meet the requirements of
EA10-13
 FAST-CAL is the most accurate in its
class!

19
Integrity in Temperature Calibration

Errors
The largest error source will probably be
due to heat conduction along the stem of
the unit under test, (UUT)
 Most users do not consider this, and
because it is not part of the manufacturers
specification they ignore it

20
Integrity in Temperature Calibration

We Do Not Ignore Stem Conduction!

E.g
A 6mm diameter Pt100 with a 30mm sensing
length will have an error of 0.1% (0.1°C @
120°C) in a bath with an immersion of 120mm
 In a FAST-CAL with immersion of 148mm the
error is 0.005% or 5mK, i.e. 20 times better!


For more information on stem conduction
look at our website and e-learning

21
Integrity in Temperature Calibration

FAST-CAL – Calibrate larger diameter
sensors for the same accuracy

E.g
What is the maximum diameter of thermocouple
that can be calibrated for an accuracy of 0.5%?
 If the immersion is 120mm = 7.5mm diameter
 In a FAST-CAL with 148mm immersion = 9.2mm


The extra immersion lets you calibrate
larger sensors
22
There is more

An insert in a Dry Block Calibrator has
an air gap between it and the heater or
cooled block, the insert too has stem
conduction and it can give rise to
surprisingly large error
23
There is more

E.g. A block with an insert 32mm diameter and
120mm deep has a depth of 3.75 x its
diameter giving a 2% stem conduction offset
Equivalent to 2°C at 120°C, 4°C at 220°C etc
 The FAST-CAL has an insert 25mm diameter
by 148mm deep or 6 x diameter equivalent to
0.5°C at 120°C, Four times better than that of
a competitors bath
24
There is more
That is why we recommend the
“Complete” option because in it we
measure the temperature of the insert –
where the actual calibration takes place
 Isotech products are better by design

25
Choice of Standards

Use our recommended
Platinum Resistance
Thermometers for high
accuracy, low
uncertainty
measurements
26
Choice of Standards

For less demanding
applications we can offer
high quality MI
thermocouples



Still allows you to measure
the insert temperature
where the calibration takes
place
Easily angled to sit under
head mounted enclosures
Low Cost
27


Mains Variation Immunity


All Isotech block baths have built in immunity
to mains variations giving you the benefit of
better stability
Isotech products are better by design
28
Certification and Traceability
All FAST-CALs are tested and certified at
Isotech
 Isotech’s NTPL laboratory has the
smallest uncertainties down to
+/-0.025°C for some metal block baths
and +/-0.00007°C at 2 Sigma for Water
Triple Point and Gallium Cells
 Isotech – confidence comes as standard

29
Software

FAST-CALs ship with Cal Notepad included
 We put benefits like thermostat testing,
setpoint programming and monitoring into the
software which is readily upgradeable and
expandable not locked into firmware that is
not accessible to you
30
Software FAST-CAL is compatible with

I-cal Easy
I-cal Easy Enables you to do
 Automatic Calibration, Certificate Printing,
Coefficient Calculator…
 Try the free evaluation version

31
Cost of Ownership

FAST-CALs have world class designed and
built instrumentation (Designed by Eurotherm)
 If anything does go wrong it takes just a few
seconds to unplug and exchanged
 Compare to competition where the whole unit
has to be returned to the manufacturer
 Eurotherm – are one of Isotech’s “Partners in
Calibration”
