Multiple-Position Hot Plate Stirrer, Digital, Model HS55

 Price List PDF price list - Torrey Pines Scientific Laboratory Equipment
The Torrey Pines Scientific HS55 digital multiple-position hot plate stirrer comes with 5 individually controllable stirring spots. The 305 x 305 mm chemically resistant ceramic heater top of the HS55 is mounted into a cast aluminum frame and is ideally suited for precise temperature control of liquid samples with a heater power of 1,400 watts.

A platinum RTD sensor located under the plate surface determines the current temperature and forwards the information to a PID control loop. Up to 800 ml of aqueous solution per stirring position can be mixed over a speed range of 100 to 1,500 rpm.

A DIN jack on the rear side of the unit accommodates the 153 mm long stainless steel immersion probe which is included with each unit and used to determine solution temperatures. In this regard we strongly recommend the use of a immersion probe for the most accurate temperature control.

The HS55 magnetic hot plate stirrer comes with a large, easy-to-read LCD. The following parameters are displayed: measured plate surface or solution temperature (by means of immersion probe), mixing speed, stirring position, count-down timer in hours, minutes and seconds as well as temperature ramp value.

All models feature a factory set electronic calibration, traceable to NIST, however, the user is able to recalibrate the unit to his own standard. A RS232 I/O port enables data collection or external PC control of the unit.
