Principles of Operation
Each Isotemp Advanced unit utilizes the latest
microprocessor technology to deliver the most reliable,
accurately controlled, ceramic top or aluminum top hot
plate on the market.
Your Isotemp Advanced unit with heating functionality
has an electronic, closed-loop feedback control which
will accurately maintain temperature setpoints from 30°C
through 300°C, 400°C or 450°C depending on models.
The Isotemp Advanced units use a Type K thermocouple
for measuring the top plate temperature, OTP and
the external probe. Both top plate surface and OTP
temperature are measured with independent analog
circuits. This provides a significant increase in safety due
to the redundancy of the circuits. It is possible to heat
certain types of metal vessels and sand baths on the
Isotemp Advanced without damaging the ceramic top or
aluminum top.
The electronic stirring speed control will maintain the
speed setpoint when the unit is loaded. The motor is
combined with a powerful magnet to provide exceptional
magnetic coupling with a stir bar.
The time feature on the Isotemp Advanced can be
programmed to turn off the stirring, heating or both. See
“Setting the Time” section of this manual.
