Intended Use
The Portavo 904(X) COND is a portable
conductivity meter. With a plain text line
on a high-contrast LCD, operation is largely
intuitive. The device variant 904X COND
is available for applications in hazardous
locations up to Zone 0.
The meter stands out by the following
features:
• Use of digital Memosens sensors
• A detachable quiver protects the sensor
and prevents it from drying out. Further-
more, it can be used for calibration.
• The rugged housing is made of a
high-performance polymer. It provides
high impact resistance and dimensional
stability even when exposed to extreme
moisture.
Overview of the Portavo 904(X) COND
Quiver
• Scratch-proof clear glass display, perfectly readable even after years
• Very long operating times with one set of batteries (4x AA) or use of a Li-ion bat-
tery for reliable operation even at high or very low operating temperatures (Li-ion
battery not suited for Portavo 904X COND for application in hazardous locations)
• Data logger with 5000 values
• Micro USB port for communication with Paraly SW 112 PC software for data evalu-
ation of digital sensors (Memosens)
• Sensoface icons provide single-glance information on the sensor condition
(page39)
• Real-time clock and indication of battery charging level
• At measuring temperatures from -20 to +100 °C the temperature detector can be
automatically identied.

Value-Added Features
Memosens
The Portavo 904 can communicate with Mem-
osens sensors. These digital sensors are auto-
matically identied and the meter switches to
the appropriate measurement method. When a
Memosens sensor is connected to the meter, it is
indicated by the logo shown on the right. Further-
more, Memosens allows the storage of calibration
data, which will be available and can still be used
when the sensor is connected to another Memos-
ens-capable device.
Sensoface
Sensoface provides quick information on the sen-
sor condition. The three "smiley" faces as shown
on the right represent the sensor condition during
measurement and after a calibration. When the
condition deteriorates, an “INFO …” message pro-
vides additional information on the cause.

Protective Cover
The front of the meter is protected by a
cover, which can be completely ipped
over and secured to the back for oper-
ation. A label on the inner side of the
cover explains the control functions and
device messages.
Hook
A fold-out hook on the back allows the
meter to be suspended. This leaves your
hands free for the actual measurement.
The nameplate is located beneath the
hook.
Protective Cover and Hook
Combined
The two parts can be combined to form
a benchtop stand, enabling convenient
and fatigue-free work with the device at
a laboratory table or desk.

Display
The meter has a three-line display for
showing alphanumeric information
such as measurement and calibration
data, temperatures, and date/time.
Additional information is provided by
means of icons (Sensoface, battery
icon, etc.).
Some typical displays are shown here.
Measuring
(display of measured value and tem-
perature)
Calibration
(Calibration by entry of cell constant)
Logger data
(display of measured value, memory
location, temperature, date and time)
Clock
(display of hours and minutes, seconds
and date)
Calibration
(with KCl solution)
