ROUND UP
Environmental management and control withThermo-Hygrometer
Fluke and HART Scientific have revolutionised environmental
monitoring for calibration labs with their model 1620A DewK
which offers Ethernet and wireless connections and upgraded
LogWare III software.
Accuracy: Two types of sensors are available from Hart
(represented locally by the Comtest Group). The high-accuracy
sensor (‘H’ model) reads temperature to ± 0,125°C over a cali-
brated range of 16°C to 24°C. Relative humidity readings are
to ± 1,5% RH from 20%RH to 70%RH. The standard-accuracy
sensor (‘S’ model) reads temperature to ± 0,25°C over its
calibrated range of 15°C to 35°C. Relative humidity readings
are to ± 2% RH from 20% RH to 70% RH. All DewK sensors
come with NVLAP accredited certificates of calibration for
both temperature and humidity, complete with data and NIST
traceability.
Ethernet and wireless capability: The DewK features built-
in Ethernet RJ45 jack and multiple DewKs can be monitored
from the same screen using the new LogWare III client-server
software. Ethernet also allows for the possibility for remote
connectivity over the internet.
Maths and statistical functions: In addition to temperature
and humidity, the DewK calculates dew point, heat index, and
rates of change for both temperature and humidity. Min, max,
and a variety of other statistics are also calculated and can
be shown on-screen.
Calibrated sensors: The DewK has inputs for two sensors,
each measuring both temperature and relative humidity, so
that the DewK canmonitor two locations simultaneously. Both
sensors can be run via extension cables to remote locations
up to 100 feet away, or one sensor can be directly mounted
to the top of the DewK. Each sensor is calibrated for both
temperature and humidity at Fluke Calibration.
Memory: The DewK has an impressive memory capacity
– enough to store up to 400 000 date- and time-stamped data
points (i.e. two years’ worth of data for both measurements
from two sensors from readings taken at tenminute intervals).
Alarms and battery back-up: Alarm settings are eas-
ily made based on temperature, the rate of change in tem-
perature, RH, the rate of change in RH, and instrument fault
conditions.

Rebranding – new name, same capabilities
Vertiv , the business formerly known as Emerson Network
Power, has officially launched under its new branding in
South Africa. Vertiv is a global provider of mission-critical
infrastructure technologies for vital applications in data
centres, communication networks, and commercial and in-
dustrial environments.The company, which is headquartered
in Columbus, Ohio (USA), has more than 20 000 employees
and 28 manufacturing and assembly facilities worldwide.
Vertiv will continue to build on the broad portfolio of product
and service offerings for power, thermal and IT management
capabilities it previously offered as Emerson Network Power,
including its industry-leading flagship brandsASCO, Chloride,
Liebert, NetSure andTrellis. Backed by over 255 service centres
worldwide, with over 3 000 service field engineers and more
than 400 technical support/response people, Vertiv is able to
support customers wherever they are across the globe.
“We have been in SouthAfrica for many years and asVertiv
we will continue to support the country’s evolving needs in IT
and digital infrastructure” added Pierre Havenga, managing
director of Vertiv in the Middle East and Africa. “We thrive
towards ensuring our technologies fulfill local customer re-
quirements to optimise their operations with the highest levels
of availability and reliability in all market segments,
from the public sector to healthcare to finance. At
the same time, we are looking at reinforcing our
partnerships and growing the local network of
technology distributors and resellers.
“South Africa is a key country for Vertiv as it
serves as the hub through which products, pre-
sales and after sales services flow for the entire
sub-Sahara Africa region, and through which all
South and East Africa transactions are processed,
including the SouthAfrican Development Commu-
nity (SADC) for a total of 25 countries,” continues
Pierre.
