1. Product Description
1.1 Introduction
The pH 50 Benchtop Meter allows for the accurate measurement of pH, mV, ORP
and temperature.
The user-friendly coloured LCD display of this product not only allows for easy
brightness adjustment and selection of viewable parameters but also presents all
necessary information, including the buffer used for calibration and a stability icon.
The high-resolution display features guided procedures that enhance the user
experience, ensuring intuitive and safe operation with high-performance outcomes.
Additionally, the display ensures accuracy and eciency through controlled processes,
constantly monitoring all operations and signalling them to the operator via a coloured
LED above the screen and self-diagnosis messages.
The meter includes an automatic pH calibration with the USA and NIST buffers up to
three points and a manual pH calibration up to two points. Additionally, it features an
automatic calibration of the redox potential of ORP at one point. The calibrated points
are shown as icons on the display screen.
1.2 Intended Use
The pH 50 Benchtop Meter is suitable for various applications, including school
laboratories, galvanic baths control, the chemical industry, titration and quality control,
food and beverage, pharmaceutical and clinical laboratories, and the water industry.
Its accuracy, eciency, and reliability make it an ideal tool for professionals and
researchers in these elds.

3. Safety Precautions
Read the following safety precautions prior to using the Benchtop Meter.
Never use the unit in any manner not specied in this manual.
• Wear personal protective equipment during the operation of the unit.
• Always install the unit on a at, stable, and non-slippery surface.
• Always unplug the power adaptor before cleaning the unit.
• Never touch moving parts. Do not move the unit during operation.
• The unit is not to be operated in a hazardous, explosive, or ammable environment
and not to be used to mix explosive or highly reactive material. Do not use the unit
under water.
• Do not use the benchtop meter if it shows signs of electrical or mechanical damage.
If any damage is found, contact your supplier immediately.
• Do not use the meter if it has been stored for a long period to time in adverse
conditions such as exposure to direct light, heat sources or places saturated by gas
or vapours, or in environments with conditions different from those mentioned within
this manual.
• Ensure that the attachments are secured properly prior to operation.
• Do not use without appropriate training. Always follow the installation instructions.
• In case of prolonged unuse, cover the BNC connectors with the special cap.
• Do not open the unit’s housing as it does not contain parts that can be maintained,
repaired, or replaced by the user.
The safety of the user cannot be guaranteed if the unit:
• Is operated with accessories that are not supplied with the unit
• Is operated with accessories that are not supplied or recommended by the manufacturer
• Is operated improperly or contrary to the manufacturer’s specications
4. Maintenance & Cleaning
• Always unplug the power adaptor before cleaning the unit.
• Wear protective gloves and safety glasses while cleaning the unit.
• Excessive amounts of liquid should be avoided. Liquids must not contact the motor.
• If used correctly and in a suitable environment, the meter does not require
maintenance.
• It is recommended to occasionally clean the housing with a damp cloth and a
mild detergent. Note that the housing is ABS/PC [acrylonitrile butadiene styrene/
polycarbonate] - it is sensitive to some organic solvents such as toluene, xylene,
and methyl ethyl ketone [MEK].
• After cleaning, ensure that all the parts are dried.
• For maintenance of the electrochemical sensors, refer to the documentation within
the packaging or contact the supplier.
• If repairs are performed by unauthorised personnel, the product warranty may
become void.

5. Installation
1. Open the packaging and gently remove the benchtop meter from the box.
2. Place the unit gently onto a rm and levelled surface.
3. Unpack every individual component.
4. Assemble the components as instructed in this manual for optimal performance.
ATTENTION! The manual should be kept with the device and all the packaging should
be kept in safe storage for at least two years for warranty purposes.
ATTENTION! If the unit is damaged on unpacking, please contact Westlab Pty Ltd
immediately.
Location and mounting
Place the benchtop meter on a at, solid, and levelled surface. Ensure that all four feet
stand on the surface rmly. Avoid installing on a slippery surface or a bench prone
to vibration.
• Keep a minimum clearance of 200mm from all directions to guarantee safe operation.
• Keep the unit away from heat or water to avoid sample temperature errors.
• Do not place the meter in an area that makes it dicult to operate the unit.
• Ensure that the surrounding environment is correctly illuminated.
• Use in a well-ventilated area.
Connecting the power supply
• Ensure that the electrical standards of the connected power source complies with
the voltage and operating frequency of the benchtop meter.
• Use the original power supply only.
• Connect the power supply plug to the connector on the rear of the meter indicated
with the 5V icon.
• Connect the power supply to an easy to reach power socket.
• The unit is equipped with a power supply that isn’t protected against liquid entry.
Therefore, it is necessary to keep all electrical cables and connections away from
any liquids and humidity.
• In the event of accidental loss of power during operation of the meter, the user isn’t
in danger of electrical shock. The meter will not automatically turn on after the loss
of power. Press the ON button to turn the meter back on.
ATTENTION! Danger of death or serious injury from electrical shock. Contact with
live components can lead to injury or death.
• Use the supplied adaptor only.
• Do not put the power supply in contact with liquids or in a condensing
environment. Avoid thermal shock.
• All electrical cables and connections must be kept away from moisture or liquids.
• Ensure that the cables and plugs are not damaged, otherwise replace them.
• During use, do not cover the power supply and/or do not place it inside containers.

Long
(3 seconds)
In measurement mode, keep one of the two buttons
pressed to change the temperature in MTC mode (manual
compensation, without probe). When the value starts
to ash, the user can change the temperature value by
entering the correct one and conrming it with .
Short In measurement mode, press to scroll through the
different parameters: pH > mV > ORP.
The correct use of the function keys and the attention in pressing them, given the
small size, eliminates the residual risk of minor damage, not probable, caused by
simultaneous pressing of the keys. Before using the meter, check that pressing the
keys has the corresponding effect on the display.
Selecting the parameter
After switching ON the meter, it will enter the measurement mode of the last
parameter used.
To scroll through the different parameter displays, press the button. The selected
measurement parameter will show in the top left of the screen. The sequence of
parameters in measurement mode is pH, mV, and ORP. By pressing the button
after the last parameter, the meter automatically restarts from the rst parameter.
In the measurement displays for the pH, mV, and ORP parameters, press the
button to start the calibration of the active parameter. (more detail later in the manual)
