The external temperature sensor PT1000 is the
Manufacture’s standard accessory. If the sensor is plugged
in and rotate the heating knob, LED displays the
temperature setting value and shifts to real value in 5
seconds. Safe circuit controls hotplate temperature.
Comparing with the temperature control of the hotplate, the
external temperature sensor can control the medium’s
temperature more precisely. The heating function will be
stopped automatically under abnormal conditions. Please
operate follow the instructions below:
•Switch OFF the instrument.
•Ensure the external temperature sensors is inserted in
the media heated.
•Switch ON the instrument and run heating function.

hotplate has a residual heat warning function. When the
heating function is switched off and the heating plate
temperature is still above 50°C, “Hot” will flash to warn
that there is a hazard of burns from the hotplate. When the
hotplate temperature drops to below 50°C, the unit will
automatically switch off. If users want to turn off the LCD
or LED immediately, just pull out the plug directly. When
the plug is pulled out, the residual heat warning function
cannot be run.

•Wear the proper protective gloves during cleaning of
the instrument.
•Before using other method for cleaning or
decontamination, the user must ascertain with the
manufacturer that this method will not harm the
instrument.
•Send in the case of service the instrument back in the

•The enamel makes the hotplate easier to care for and
more resistant to acids and bases. Because of it,
however, the hotplate is also more susceptible to
extreme fluctuations in temperature and the force of
impact. This can result in cracks forming or the
coating flaking off.
