Product Description:
The EchoTherm HP30 and HS30 are products of years of experience in design, manufacturing, and marketing of digital hot plates and stirring hot plates. That experience was focused into the design of these units with the goal of making them the easiest to use and most accurate fully featured hot plates and stirring hot plates in the world. They are so simple to use it is surprising. Temperature measurement of a solution is accurate to 1% over the entire temperature range using a 100-ohm platinum RTD sensor and measurement system. Calibration of temperature is electronic and stored in memory. Calibration is set at the factory but can be done easily in the field using the probe calibration kit offered as an accessory.
Heater tops are ceramic glass for all stirring hot plates and ceramic glass or milled flat cast aluminum for the hot plate only. The ceramic glass tops are a brilliant white flat glass set in a cast aluminum frame that are easy to clean and impervious to chemical spills. The ceramic glass is different than the cast plate with curved sides used by other manufacturers. These cast tops may have stress in them from the molding process and have been known to fracture when heated or put under stress by their mounting clips. The flat glass top of the Torrey Pines Scientific units eliminates this stress. Mounting them in a cast aluminum frame gives the additional advantage of a cool edge to the heating surface to help prevent accidental burns. The glass tops have efficient 600-watt heaters that can raise the plate surface temperature to 450°C in just a couple of minutes. The cast aluminum tops are flat to within 0.01 inches corner to corner and have 740-watt heaters that can raise the plate surface to 400°C in under ten minutes.
The chassis on both models is cast aluminum designed to keep spills and heat out of the electronics. They are coated with chemically resistant epoxy based paint for durability. The membrane switch and display areas are covered with a replaceable, clear, soft vinyl cover to help keep spills off them. All units come complete with a six-foot long, three wire grounded, detachable line cord, fuse holder, and main ON-OFF switch. Both high and neutral lines are fused for safety.
