Torrey Pines Scientific, Inc. announces its NEW EchoTherm Digital Stirring Hot Plate for use in chemical, pharmaceutical, environmental, biochemical and other laboratories where reproducible and accurate sample preparation and 
experimentation are a must. The unit displays target and actual temperature, temperature ramp rate, stirring speed and time. The 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 3 minutes. Surface or solution temperature can be controlled directly using the appropriate PID control loop to 1°C of the target. Accuracy is 1% of the reading using platinum RTD circuitry and 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. An RS232 I/O port, count timer, and auto-off setting all come standard with the unit. The Model HS30 is available in 100, 115, and 230 VAC, 50/60 Hz and all units are UL, CSA, and CE certified.
