New Aluminum Topped Programmable Hot Plate for Work with Solids Directly on Heater Surface

Carlsbad, CA - Torrey Pines Scientific,
Inc. announces its NEW EchoTherm™
Model HP61A Programmable Hot Plate
with a 12” x 12” milled-flat cast aluminum
heater top.

Applications include wafer processing and
annealing, polymer engineering, baking
photo resists, wax and glue heating and
bonding, micro fabrication and
encapsulation, surface mount soldering,
and heating any sample directly on the
heater surface.

The heater plate is 12" (305 mm) x 12" (305 mm) milled-flat cast aluminum for even heating
across the surface. The temperature range is from ambient to 450°C controlled to ±1°C of the
target. Accuracy is 1% of the reading using a platinum RTD sensor in the heater top. The unit is
supplied with a temperature calibration certificate traceable to NIST.

With the EchoTherm™ Model HP61A programming is done through the front panel membrane
switch and liquid crystal display. The unit stores ten programs in memory of as many as 10
steps each where each step is a temperature, temperature ramp rate if wanted, and time. Each
program can be made to repeat automatically from 1 to 99 times or infinitely. All programs are
stored electronically. Temperature ramping rates are settable in 1ºC/Hour increments from
1ºC/Hour to 450ºC/Hour.

The unit has a countdown timer with alarm and user settable Auto-Off, and RS232 I/O port for
computer control or data logging. The Model HP61A is available in 100, 115, and 230 VAC,
50/60 Hz models.
