Specic Test Report

The Portavo 908 MULTI is a portable multi-
parameter meter for use with Memosens
sensors or the Model SE 340 optical oxygen
sensor. The micro USB port allows the
meter to be connected to a printer for
printing currently measured values or a
calibration record including sensor data.
The meter automatically recognizes the
connected sensor and accordingly selects
the corresponding process variable.
By simply replacing the sensor, the meter
can be used for measuring conductivity,
pH/ORP or oxygen (also optical).
Operation is simple and intuitive,
supported by detailed information and
help texts.
Overview of the Portavo 908
The meter stands out by the following features:
• Use of digital Memosens sensors or the Model SE 340 optical oxygen sensor
• A detachable quiver protects the sensor and prevents it from drying out.
Furthermore, 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.
• Scratch-proof clear glass display, perfectly readable even after years
• Long operating time with one set of batteries (4 x AA) or use of a Li-ion battery for
reliable operation even at high or very low operating temperatures
• Data logger with 10,000 values
• Micro USB port for communication with Paraly SW 112 software for data evaluation
of digital sensors (Memosens) or connecting a printer
• Sensoface icons provide single-glance information on the sensor condition
• Real-time clock and indication of battery charging level
• Automatic compensation of ambient pressure for oxygen measurement
• At measuring temperatures from -20 to +100 °C / -4 to +212 °F, the temperature
detector can be automatically identied.

Value-Added Features
Memosens
The Portavo 908 can communicate with
Memosens sensors. These digital sensors are
automatically identied 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.
Furthermore, Memosens allows the storage of cal-
ibration data, which will be available and can still
be used when the sensor is connected to another
Memosens-capable device.
Sensoface
Sensoface provides quick information on the
sensor condition. The three“smiley” faces as shown
on the right represent the sensor condition during
measurement and after a calibration. When the
condition deteriorates, a status message gives a
hint to the cause.
Calimatic (pH)
Calimatic is a very convenient method for pH
calibration with automatic buer recognition.
You only have to select the buer set with the
buers used. The buers can then be used in any
order.
Digital Optical Oxygen Measurement
Digital optical oxygen measurement reduces
maintenance eort and simplies handling.
Overview of the Portavo 908

10 Overview of the Portavo 908
Protective Cover
The front of the meter is protected
by a cover, which can be completely
ipped over and secured to the back for
operation.
Hook
A fold-out hook on the back allows the
meter to be suspended. This leaves your
hands free for the actual measurement.
The rating plate is located beneath the
hook.
Protective Cover and Hook
Combined
Cover and hook can be joined together
to form a benchtop stand allowing com-
fortable and fatigue-free working at a lab
bench or desk.

12 Start-Up
Inserting the Batteries
With four AA batteries, the Portavo has an
operating time of up to 500 h when oper-
ated in logger mode (see page 42).
Open the battery compartment on the
rear of the device. Be sure to observe the
correct polarity when inserting the batter-
ies (see markings in the battery chamber).
Close the battery compartment cover and
screw it handtight.
Check the shipment for transport damage and completeness (see Package
Contents).
NOTICE!
Do not operate the device when one of the following conditions applies:
• the device shows visible damage
• the device fails to perform the intended function
• prolonged storage at temperatures above +70 °C / +158 °F
• severe transport stresses
In this case, a professional routine test must be performed.
This test should be carried out at our factory.
A special lithium-ion battery (ZU 0925) suited to the battery compartment is avail-
able for the Portavo 908. Only this battery type can be charged directly from the USB
port.
A battery icon in the display indicates the battery power level:
Icon fully lled Batteries at full capacity
Icon partially lled Battery capacity is sucient
Icon empty Battery capacity not sucient;
calibration is possible, no logging
Icon blinks Only a few operating hours remaining,
measurement is still possible
NOTICE! It is absolutely necessary to replace
the batteries.

13
Connecting a Sensor
You can connect a Memosens sensor for pH/ORP, conductivity or oxygen measure-
ment to the Portavo 908. The Model SE 340 optical oxygen sensor can also be con-
nected. The meter automatically recognizes the connected sensor and accordingly
selects the corresponding process variable. Memosens is signaled in the display.
Note that only one sensor may be connected to the meter at a time.
Separate Temperature Probe
After power-on, a separate temperature probe is automatically recognized. If you
want to replace the temperature probe, you must switch o the meter and then
switch it on again.
Start-Up
Memosens sensors have a cable coupling, which allows convenient replacement of
sensors while the cable remains connected to the meter.
The connecting cable is connected to socket bor e.
Connections
a - Micro USB port
b - M8, 4 pins, for Memosens lab cable
c - Temperature probe GND
d - Temperature probe
e - M12, 8 pins, for flexible connecting

You can use meas or on/o to switch the meter on:
• With meas, the meter immediately switches to measuring mode.
• With on/o, rst a self test is performed and then the calibration
data and settings are displayed before the meter switches to
