Preface
Thank you for purchasing this Camlab Choice product. For your safety and to
get the best product performance, please read these instructions carefully
prior to use.
Camlab Choice products are carefully selected from leading worldwide
manufacturers to offer outstanding performance and value. All of our Camlab Choice
range products are put through their paces by our product team and fully inspected
by our engineers. Please contact us if you have any questions or require technical
application support.
The MS-H280-Pro round ceramic coated Steel Hotplate/Stirrer has a double LED
display and heats up to 280 ° C, with a stirring speed range of 100-1500rpm. Heating
and stirring are controlled independently and each function can be used separately
or in combination. This instrument has the ability to connect a PT1000 external
temperature sensor (available separately) to enable real-time monitoring of the
temperature of the stirred sample itself, rather than just the plate temperature. It is
Capable of stirring up to 3L of liquid with a maximum viscosity of 100mPas. For
samples with a viscosity of 100-300mPas, it is recommended that the unit is
operated at a speed of no more than 500-600rpm. For samples with a viscosity
greater than 300mPas, we recommend the use of an overhead stirrer

Important safety notices
Users of the MS-H280-pro should read this manual carefully prior to use, following
the instructions and notices with caution. Do not operate the hotplate stirrer in a
manner not described in this user manual. Whilst these safety instructions are here
to help prevent all incidents it is important you are alert for any unexpected
occurrences.
Warning!
•Read operating instructions carefully before
use
Caution! Risk of burns
•Be aware of residual heat once switched off
•Do not touch instrument and housing when it is
switched on
Grounding
•Ensure the instrument’s electrical connection
is well protected before use
•Make sure the operating voltage and mains power supply voltage match and
ensure the socket is properly grounded
•When working with the MS-H280-Pro, use appropriate PPE to avoid risk of
injury caused by:
oSplashing and evaporating liquids
oThe release of toxic or combustible gases
•Ensure instrument is set up on a stable, flat surface in a dry and fireproof
environment.
•Gradually decrease the speed of the stirrer if:
oStirring bar breaks away due to high speed
oThe instrument is not running smoothly, or liquid container has moved
to an unsteady position on the base plate
•Ensure the temperature is set to at least 50°C lower than the flash/fire point of
the liquid being heated.
•Do not use with flammable materials or liquids with a low boiling point.
•Ensure you select a suitable container shape, size and material for the task
and do not overfill container.
•Inspect instrument and accessories for damage prior to each use. Do not use

you notice any damage.
•Safe operation is only guaranteed with the described accessories.
Accessories must be securely attached to device ensuring they remain
connected during operation. Always disconnect from the mains before fitting
accessories to the instrument.
•When an external temperature sensor is used, the tip of the measuring sensor
must be at least 5-10mm from vessel bottom and wall.
•The instrument can only be disconnected from the mains power supply by
pulling out the connector plug.
•Ensure that the mains power supply cable does not touch the hotplate.
•Do not cover the device.
•Do not put pressure on ceramic hot plate surface, as this may lead to
breakage.
•Keep away from strong magnetic fields.
•Ensure all users of the instrument are trained in its safe operation.

Permitted conditions of operation
This device is designed to operate under the following conditions:
•Indoor use only
•Use in well ventilated area
•Permitted ambient temperature range – 5 - 40°C
•Maximum permitted humidity – 80%
•Minimum clearance of 10cm from walls and any other items
•Capable of stirring up to 3L of liquid with a maximum viscosity of 100mPas.
For samples with a viscosity of 100-300mPas, it is recommended that the unit
is operated at a speed of no more than 500-600rpm. For samples with a
viscosity greater than 300mPas, we recommend the use of an overhead
stirrer

Setting up
You must observe a minimum distance of 10cm between the unit and any other
object, including the wall.

Operation
The MS-H280-pro magnetic stirrer hotplate has independent controls for temperature
and speed. Both of these functions can be used together and separately if required.
For the stirring function, an appropriate magnetic stirring bar is required.

Description
HOT
Residual heat warning, displays HOT when temperature is
above 50°C
Probe icon to left of the LED display area is lit when a
PT1000 is plugged into the instrument.
Warning:
Residual heat warning does not function when unit is turned off using
the switch. It is advisable to turn functions off using dials until unit
has cooled sufficiently and unit no longer displays ‘HOT’ before
powering off fully.
Instructions for use
1. Set up the instrument in an appropriate location and connect to a power
supply. Switch the unit on using the switch located on the side of the unit –
labelled as (2) on figure 2a.
2. Fill an appropriate heat resistant vessel with the liquid to be stirred and/or
heated and place on the work plate. If you are using the stirring function, add
an appropriate magnetic stirring bar.
3. Heating. Rotate the temperature dial (labelled (1) on figure 2) clockwise to
your desired target temperature and push in the dial to commence heating. To
turn heating off, push the dial in again. When heating is not in use, the
temperature LED will display as ‘OFF’.
4. Stirring. Rotate the dial to your set speed and push in to turn the function on.
It is advised to start the speed slowly and gradually increase as required, this
will allow for stable operation with the stir bar. To turn stirring off, push the dial
in again.
5. When finished, ensure each dial is pushed in and the LED displays ‘OFF’ for
both temperature and speed. Use the ON/OFF switch located on the left hand
side and unplug from the mains supply.
Using the temperature sensor
The external temperature sensors Pt1000 can be used as an accessory to this
instrument and allows for more accurate monitoring of the temperature of the liquid
being heated. When an external temperature sensor is used, the tip of the measuring
sensor must be at least 5-10mm from vessel bottom and wall.
1. Ensure unit is fully powered off prior to plugging in temperature probe.
2. Attach the probe holder to the probe holder port. Plug the probe into the probe

socket at the rear of the unit and secure probe into the holder. Turn the
instrument on.
3. The temperature display will show the actual temperature of the sample as
measured by the P1000 probe.
Maintenance and Cleaning
•Proper maintenance and cleaning can keep instruments working properly and
will lengthen its lifetime.
•ABS casing will give some chemical resistance to weakly acidic and alkaline
liquids.
•Do not spray your chosen cleaner directly on to the unit when cleaning
•Ensure the unit is unplugged from the power supply and cooled down
completely before commencing with cleaning.
•Wear appropriate PPE equipment during the cleaning process.
•Only use recommended cleaners below:

•If the instrument will not be in operation for an extended period of time, please
switch off and store in a dry, clean environment.
Faults and Troubleshooting
Instrument is not powering on
•Check whether the power line is plugged in
•Check whether the fuse is broken or loose
Stir speed is not reaching set point
•Excessive medium viscosity may cause abnormal speed reduction of the
motor. This instrument has only been verified for stirring water and mediums
with a similar viscosity). Try the unit with a small quantity of water to check the

stirring function.
Unit is not powering off
•The residual heat warning may be showing as ‘HOT’ if unit is above 50°C but
has not been fully powered off. Try using the switch on the side of the unit and
unplugging from the mains to fully power off.
If these faults cannot be resolved, please contact Camlab Technical Support on
