Torrey Pines Scientific HP20, HS20, ST20 DigiLog Stirrers, Hot Plates-Stirring Hot Plates

DISCONTINUED ITEM-Replacement Models Available: Digital Hot Plates and Stirring Hot plates

The new Digilog™ series represents state of the art electronic technology applied to simple hot plates and stirrers. These units combine the features of both analog and digital stirrers to make reliable, easy-to-use units that are priced like simple analog units

Digital Features:

• 3-digit display of heater power as a percent of total range for easy resetting. No need to mark the heater knob or front panel.
• Membrane keyboard setting of all parameters. Easy scroll up or down settings. No mechanical controls at all.
• Two memory keys for saving your two favorite combinations of temperature and stirring speed for one button instant recall at any time.
• “Plate Hot” red LED illuminates when plate temperature goes above 50°C and stays lit when the plate is hot even after the unit is turned off.
• Main power ON/OFF button on the front panel for easy, safe access. Prior settings are retained when the unit is turned off and the unit will return to those settings automatically when turned on again.
• Indicator lights and ON/OFF buttons for heater and stirrer power. Turn either off with a single button. Turn on again and the prior settings remain.
• Heater power regulated even through changes in line voltage. Heater temperature stays much more stable than standard analog units.
• Low plate temperature settings as low as 30ºC.
• Heater drive software written to go up to setting quickly, reduced heating times.

Analog Features:

• Inexpensive price. These units cost less than most strictly analog units.
• Compact size. They are 10” (25.4 cm) deep x 7” (17.78 cm) wide x 4.5” (11.43 cm) high.
• Ruggedness. Will support over 30 lbs (66.6 kg).
• Easy to use. Simplified scroll up and scroll down settings.
• Simple to service if needed. No special service training required.
• Fused AC input line.
• Compact, rugged cast aluminum chassis that is designed to keep spills out of the case.
• Safety. All controls are mounted forward of the heater plate for safety. All electronic controls are on one simple PC board, and have red indicator LED’s that illuminate when activated
• The stirrer features a circular disk magnet capable of lifting 20 pounds (9 kg) coupled to a strong stirrer motor, making these units capable of stirring 2 L of solution. The stirrer range is from 100–1500 rpm
