The Liquiline To Go Ex CYM291 is
a portable multiparameter meter for
measuring pH, ORP, conductivity
or oxygen. With a plain text line on a
high-contrast LCD, operation is largely
intuitive.
Overview
Quiver
The meter stands out by the following features:
• Application in hazardous locations up to Zone 0
• Use of digital Memosens sensors
• 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
• Very long operating time with one set of batteries (4 x AA) for reliable operation
even at high or very low operating temperatures
• Data logger with 5000 values
• Micro USB port
• Sensoface icons provide single-glance information on the sensor condition
(page9)
• Real-time clock and indication of battery charging level

Value-Added Features
Memosens
The Liquiline To Go Ex CYM291 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 calibration 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, an “INFO …” message gives
a hint to the cause.
Programmed buers
“Programmed buers” is a very convenient method
for pH calibration with automatic buer recogni-
tion. You only have to select the buer set with the
buers used. The buers can then be used in any
order.

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
suspending the meter. 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.
