Torrey Pines Scientific, Inc. offers its new EchoTherm™ Programmable Digital Stirring Hot Plate for use in chemical, pharmaceutical, environmental, biochemical, and other laboratories. With the EchoTherm™ Model HS40, programming is done through the front panel membrane switch and full-functioned custom liquid crystal display. The unit can store 10 programs in memory of as many as 10 steps each where each step is a temperature, temperature ramp rate, stirring speed, and time. Each program can be made to repeat itself automatically from one to 98 times – or infinitely if wanted. All programs are stored electronically.

Heater plates are 8" (20.3 cm) x 8" (20.3 cm) white, solid ceramic glass for excellent chemical resistance and quick heating. The plate surface can be heated from ambient to 450 °C in less than three minutes. Plate surface temperature or solution temperature can be controlled directly to 1 °C of the target. Accuracy is 1% of the reading using platinum RTD circuitry. The units are supplied with temperature calibration certificates traceable to NIST.
