Company Review

Comtest (PTY) Limited
The Comtest Group, Fluke’s
authorised test and measurement
distributor for Southern Africa, has
introduced the 9190A Ultra-cool
field metrology well. This is a small,
lightweight and accurate dryblock calibrator with best-in-class
stability.
The 9190A is ideal for
pharmaceutical, biomedical and
food processing applications that
demand strict quality control and
regulatory process compliance,
including on-location validation and
calibration of RTDs, thermocouples,
thermometers, and other
temperature sensors.
The 9190A conforms to
EURAMET cg-13 guidelines for
best measurement practices for
temperature dry-block calibrators.
This ensures that the 9190A
specifications for accuracy, stability,
axial (vertical) uniformity, radial
(well-to-well) uniformity, loading and
hysteresis have been thoroughly,
and carefully defined and tested.
It has a wide temperature
range (-95 to 140°C) to cover the
coldest and warmest temperatures
required in pharmaceutical,
biomedical and food processing

applications, operating at ultra-cold
temperatures not typically available
with a calibration bath. The 9190A
uses no bath fluids, keeping clean
rooms clean, making it easier to
transport and delivering faster
heating/cooling rates. It offers
best-in-class temperature stability
(± 0.015°C) for consistent, accurate
results.
The 9190A with “process” option
features 4-20mA connectors,
a reference thermometer input,
four-wire PRT/RTD input with
an accuracy of ±0.02°C and
a reference sensor control to
minimise the effects of the axial
gradient when a reference PRT is
aligned with short sensors.

Alphalab Eng cc
Fume cupboards are the single
most important factor to be
considered when planning a
laboratory. Toxic fumes can cause
health problems for staff and
in extreme cases death, while
corrosive fumes can cause severe
damage to sophisticated and
expensive equipment.
Alphalab is a pioneer in the
evolution of the basic fume
cupboard into the modern and
sophisticated piece of laboratory
equipment it is today. Their fume
cupboards offer an aerodynamic
design, give exceptional
performance and provide
the highest quality laboratory
ventilation. These principles are
manifested in Alphalab’s highly
successful Constaflow™ and
Inductaflow™ range of fume
cupboards.
The Alphalab fume cupboards
are designed to meet the most
stringent operating conditions
and are specified in almost all
major laboratory projects across
the country, and are the only
units available which have easily
replaceable individual panels both
internally and externally, making
them cost effective to maintain,
since unlike all the other units
available, in the local market,
not the whole expensive fume
cupboard is replaced.
The company has a team
of in house specialists that will
assist their customers from the
design stage, right through to
final commissioning of the entire
installation.
A range of laboratory furniture in
high quality steel is available, and
for the smaller budget a melamine
option can be supplied. Various
worktops can be supplied to suit all
laboratory applications.
All products are locally
manufactured and designed, so
that Alphalab can control the quality

and service back up. Also this
ensures that there are no excessive
delays in waiting for parts, which is
often the case when using imported
products.
So, if your lab needs a high
quality, reliable product from a
company with more than 47 years
of experience in the market place,
contact us at Alphalab.
Alphalab would also like to take
this opportunity to wish all of their
dedicated customers a successful
and prosperous 2014, and they
look forward to being of service to
you in the New Year.
