Humidity transmitter with Ethernet – Your benefits at a glance
Ethernet finally also for humidity transmitters
Testo, as the first supplier worldwide of humidity measurement
technology, offers an Ethernet interface for humidity transmitters.
Now, parallel to the use of analog outputs for regulation purposes,
integrated measurement data monitoring from the the field to
management level (e.g. data from production available in the office) is
made possible easily, efficiently and at a competitive price.
Ethernet is prevalent in almost all office networks so that installation
work is kept to a minimum when the humidity transmitter is
connected to the network structures already in existence.
The new testo 6651 and testo 6681 humidity transmitter generation is
designed for process monitoring in HVAC, process and compressed
air technology. With solutions for highest accuracy as well as for
special applications (high humidity, H 2
O 2
sterilisation processes, trace
humidity applications, etc.) unrivalled cutting edge technology is
available for measuring humidity.
Developed for practical use
The Ethernet module is an “intermediate layer” (sandwich design)
which is already built into the testo 6651 and 6681 transmitters in the
factory. It can also be subsequently easily and quickly retrofitted on
site.
Two LEDs signal the status of the power and LAN connection to the
system operator responsible.
By using an Ethernet plug suitable for industry, IP65 housing
protection can be guaranteed so that the transmitter withstands the
sometimes tough and demanding conditions of industrial processes.

(intermediate layer)
Process reliability and time saved by measurement data monitoring
Networking transmitters using Ethernet provides considerable benefits in a number of applications such as for monitoring laboratories,
warehouses, production rooms, cleanrooms or drying systems. In addition to transmitting the readings signals by analog outputs to a control
system, measurement data can also be simultaneously recorded, documented and visualised using Ethernet. If necessary, it is also possible to
alert the person responsible for the process.
Easy to install
High transmission speed
Consistency of data
=> High accuracy level since
no signal conversion is
needed

Prevalent in almost all office
networks
⇒ Integration of transmitters in

Measurement data monitoring using Ethernet
Overview of testo 6651 and testo 6681 product line
Process requirement
The testo 6651 and testo 6681 humidity transmitter
generation stands out on account of a number of world
innovations which provide for a reliable and servicefriendly
application which in turn means highest efficiency
levels and process reliability:
– Replaceable, digital probes
– Early warning system and self-monitoring (preventive
maintenance)
– Versatile adjustment options
– Integrated log to save parameterization, adjustment and
message history
– Optional relay outputs
You will find more detailed information about these
products in the Catalogue: “Stationary Measurement
Solutions for HVAC and Process”.
Application areas
testo 6651 + Ethernet module
HVAC and industry:
Critical climate, cleanrooms
testo 6681 + Ethernet module
Industry:
Critical climate, cleanrooms, drying

environment etc.
testo 6651 and testo 6681 transmitters as well as digital testo 6600 and testo 6610 probes
Deciding on testo 6651 or testo 6681 depends mainly on the probe options in addition to the question about housing material (testo 6681:
metal housing) and the humidity parameters to be used. In the case of both transmitters, an Ethernet module is available as an option.

1. Measurement data monitoring using testo Saveris TM and humidity transmitter
The Ethernet module with testo 6651and
testo 6681 transmitters can be operated in
two modes:
1. Integration of transmitter in the testo
Saveris measurement data monitoring
system
2. Integration of transmitter in customer’s
monitoring system (open log)
1. testo Saveris now fit for all humidity
applications
If the Ethernet module is operated in the testo
Saveris mode, testo 6651 and testo 6681
transmitters can be easily implemented in the
testo Saveris measurement data monitoring
system. In addition to actual measurement
data documentation and visualisation using
testo Saveris software, there is also the
option of notifying the person responsible for
the system if limits are exceeded.
In this operating mode, the transmitter has an
internal data store which prevents data from
getting lost if the LAN connection breaks
down. All of the humidity parameters (e.g.
%RH, g/m³, g/kg, ppm, etc.) can be
transmitted. The transmitter is parameterised
using P2A software or the transmitter’s
operating menu.
While monitoring using testo Saveris, PLC
control (if required) is possible with the
transmitters.
In addition to the testo 6681 transmitter
humidity probes, there are now also probes
available for special applications such as high
humidity, trace humidity, corrosive
substances or H 2
O 2
atmospheres. The probe
options also facilitate direct installation on
ducts as well as the monitoring of processes
to 180 °C using cable probes.

testo Saveris base
The base is the heart of the testo Saveris measurement
data monitoring system and can save 40,000 readings
per measurement channel independently of your PC.
Readings, system data and alarms can be called up on
the Saveris base display.
testo Saveris software
testo Saveris software is easy to use and has an intuitive
user interface. Saveris software is available in two different
versions: SBE (Small Business Edition) or PROF
(Professional) software version with diverse additional
options. If external access to the measurement data is
required from outside, Internet access can be set up to
display all measurement data.

2. Humidity transmitter in customer’s system
2. Integration of transmitter in customer’s system
If the “Supplied by customer” operating mode is selected in the transmitter’s Ethernet module, the intermediate layer functions as
an XML server. Data is transmitted as an XML data set. Simple integration into the user’s system is possible on account of the
disclosed log.
Parameterizations, analyses/tests and queries about the history data in the transmitter can be carried out or called up using
Ethernet (data sets) “from above” (using your PC).
