Shown above are the keyboard and display for the HS65 Programmable Digital Hot Plate/Stirrer.
This unit has 5-stirring positions and is the most complex unit in the series. Other models in the
series will have a single stirring position or no stirrer at all. The keypads will vary depending
upon the keys needed for the units in this series with less functions.
The front panel has a tactile touch membrane keyboard with audible feedback. The keyboard is
used to set all operating parameters. The display is a LCD type made up of rows of numbers and
several icons which function to display all parameters when the unit is running and during
setting. When the unit is turned on, the display will come on and show the actual plate surface
temperature. If a probe is used, it will display the probe temperature. The timer and stirrer
functions will show zeros.
