Product Description:
The
chart above shows a typical program that can be stored
in memory and run at any time. The program can also
be instructed to repeat itself from 1 to 98 times,
or infinitely if wanted.
Torrey Pines Scientific EchoTherm programmable digital
stirring hot plates are the most advanced and easy to use
units available. In manual operation, simply select the
parameter to be set and scroll the UP or DOWN ARROW to the
value needed. The unit will do the rest. In the programmable
mode, routines can be stored for instant recall and use.
Run any program by touching RUN, selecting the program number
using the UP and DOWN ARROW, and ENTER. The routine stored
will run automatically, without attention, and exactly the
same time after time.
Programs can be simple or complex depending
upon the need. Multiple temperatures, temperature ramp rates,
stirring speeds and timed events can be stored. When run,
the unit monitors the program to be sure it runs exactly
as written. SET IT AND FORGET IT.
The units
use a 100 ohm platinum system to measure temperature.
There is a sensor built into the heater plate that is used
with the heater plate control loop software to control
the
heater plate temperature. When using an accessory temperature
probe, sample temperature of a solution can be set and
controlled
directly using the temperature probe control loop. Four
temperature probes are available. Two stainless steel probes,
one 6” and one 10” in length, are the most commonly used.
For aggressive chemicals, solid Teflon and borosilicate
glass are available in 6” lengths. The glass probe should
be used for aggressive chemicals at solution temperatures
above 260°C. Calibration for both plate and probe sensors
is done at the factory and stored in CMOS. The units are
provided with certificates of calibration traceable to NIST.
Calibration also can be done by the user, using local standards,
by following the instructions in the user’s manual.
The heater top is solid ceramic glass that is flat, white,
and impervious to most chemicals. The ceramic glass plate
is held in a cast aluminum frame. Unlike other ceramic glass
tops, it has no folded edges that can cause built-in stresses
that can cause the tops to crack. It is excellent for working
with solutions in a beaker. The ceramic top will heat to
450°C in about 2 minutes.
The chassis is cast aluminum designed to keep spills and
heat from the electronics, and it is coated with chemically
resistant epoxy paint. The membrane switch and display are
covered by a replaceable clear, soft, vinyl cover designed
to keep off dirt and spills. All units come with a six-foot
long, three wire, grounded, detachable AC line cord, fuse
holder, main ON-OFF switch and instruction manual.
