The new EchoTherm Digital Stirring Hot Plate from Torrey Pines Scientific Inc. is ideal for use in chemical, pharmaceutical, environmental, biochemical and other laboratories, where simple, reproducible and accurate sample preparation and experimentation are a must. With this easy-to-use hot plate, all functions are set through the front panel membrane keypad and full-functioned custom liquid crystal display. The unit displays target and actual temperature, temperature ramp rate, stirring speed and time. 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 using the appropriate PID control loop to 1 C of the target. Accuracy is 1 percent of the reading using platinum RTD circuitry. The units are supplied with temperature calibration certificates traceable to NIST. Stirring speed is 100 to 1500 rpm and controlled by optical coupler to 10 rpm. Count down timer with alarm and user settable auto-off are standard. An RS232 I/O port also is standard with the unit. Various sample probes are available as accessories. The Model HS30 is available in 100, 115 and 230 VAC, 50/60 Hz models. All units are UL, CSA and CE certified.
