NEW Corrosion Resistant Stirring Hot Plates

CARLSBAD, CA . . . Torrey Pines Scientific announces its NEW EchoTherm™ Programmable Corrosion Resistant Digital Stirring Hot Plates for use with aggressive chemicals in environments where other stirring hot plates would be quickly destroyed by vapors or spills. 

The EchoTherm™ Model HS70 Programmable Stirring Hot Plates are designed to be purged using an inert gas through a fitting on the rear of the chassis.  Purging provides a positive pressure inside the unit to prevent corrosive gasses from entering the chassis and attacking the electronics or stirring mechanism.

These units feature 10-program memory with 10 steps per program, temperature ramping, RS232 I/O port, membrane keyboard, and full function liquid crystal display where all parameters are continuously visible. 

Heater tops are 8" square solid ceramic with 600 watts of power.  Temperatures can be set to 450°C. The units are readable and settable to 1°C.  Accuracy is 1% over the entire temperature range.

Temperature control is by PID software and is controlled to ±1°C or ±1ºF.  Stirrer speeds can be set from 100 to 1500 rpm.  Temperature ramping can be set from 1ºC/hour to 450ºC/hour in 1ºC increments.  

The built-in timer is settable to 99 hours and is readable to 1 second.  It has an audible alarm with user settable auto-off for turning off the heater and stirrer when the timer counts down to zero.  The units are supplied with a 6” Teflon immersion probe for controlling solution temperatures directly.

All units are available in 100, 115, and 230 VAC, 50/60 Hz models. They are "Made in the USA" and are UL, CSA and CE or equivalent agency certified and available in voltages for use anywhere in the world.

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. Complete walk-away automation.

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.
