Fluke 5020A
Thermo-Hygrometer
Technical Data
Comprehensive and precise
environmental monitoring of
temperature and humidity
The Fluke 5020A Thermo-
Hygrometer is a dual-sensor,
graphical data logger / analyzer
offering precise real-time and
historical display and analysis of
temperature and humidity data. It
is an ideal solution for environ-
ments where accurate ambient
temperature and humidity must be
monitored and recorded, including
calibration, research and medical
testing laboratories, or pharmaceu-
tical and food storage applications.
The 5020A also replaces paper-
based humidity chart recorders,
eliminating the associated problems
with paper, ink, records storage,
and accuracy.
Key features:
Dual inputs provide
exceptional accuracy
The Fluke 5020A has two inputs
with removable sensing probes.
Each probe stores its own calibra-
tion constants, allowing probes to
be used interchangeably between
channels and between 5020A
units while retaining full calibration
integrity.
Two types of probes are avail-
able. The “S” model provides
standard accuracies of ± 0.25 °C/
± 2 % RH, while the “H” model
provides accuracy of ± 0.125 °C/
± 1.5 % RH. Both probes can be
connected to optional extension
cables and mounted in remote
locations up to 50 feet away from
the 5020A mainframe using the
optional probe wall mount bracket.
Alternatively, one probe can be
mounted directly to the top of
the 5020A.

The 5020A calculates dew point,
heat index, and rates of change for
temperature and humidity. Min,
max, and a variety of other statis-
tics are calculated and can be
shown in more than 16 different
user configurable display formats
and more than 12 display parame-
ters. Daily summary statistics,
including min, max, and maximum
rates of change are stored for the
most recent 60 days.
User selectable display parameters
Alarms
Alarms may be set based on tem-
perature, RH, or on rate of change
of either parameter with the Fluke
5020A. Alarms are recorded to
the data file as well as giving the
user the option of a visual alarm
(display flashing), audible alarm
(beep) enunciation, or both. In
addition to the setting of alarm
points from the easy-to-use
keyboard and menu system of the
5020A, alarms can be set using
the 5020A-LW3 configuration,
logging and trending software.
viewed from any MET/CAL soft-
ware station in your system. This
unique number also provides iden-
tification required for traceability in
quality and regulatory records.
Optional software retrieves,
stores, analyzes data
5020A-LW3 for Fluke software is a
versatile application that retrieves
data from the Fluke 5020A and
stores it in a single database, to
provide flexible, real-time and his-
torical data management. You can
view data in easily customized
graphical and statistical formats for
one or both sensors at user-
defined time intervals. View real-
time data as it streams into a chart
format customized for your particu-
lar application.

Calibration
Software interface
The Fluke 5020A is easily inter-
faced to Fluke’s MET/CAL
®
Plus,
using 5020A-LW3 software. This
unique feature allows MET/CAL
Plus
software (versions 7 or higher)
to read temperature and humidity
from the 5020A directly into a cal-
ibration record as you start to run
a procedure. All the environmental
information required for your cali-
bration becomes a permanent part
of the calibration record – without
requiring you to enter the data
manually or add it later when you
create a report. And using the
5020A with MET/CAL
Plus
software
is easy, allowing you even greater
automation and convenience.
