Torrey Pines Scientific EchoTherm programmable digital hot plate

Click2Contact

The Torrey Pines Scientific EchoTherm programmable digital hot plate features a milled-flat cast aluminium top. It is particularly suited for use in precisely heating solids like silicon wafers, electronic chips, displays, adhesives and for doing photo-resists.

With the easy-to-use EchoTherm Model HP40A, programming is done through the front panel membrane switch and full-functioned custom LCD.

The unit can store 10 programs in memory of as many as 10 steps each where each step is a temperature, temperature ramp rate if wanted and time. Each program can be made to repeat itself automatically from 1 to 98 times or infinitely.

Heater plates are 203 x 203 mm milled-flat cast aluminium. The plate surface can be evenly heated from ambient to 400°C in less than 10 min. Plate surface temperature is controlled directly using the PID control loop to 1°C of the target.

Accuracy is 1% of the heater setting over the entire range. Temperature sensing is by platinum RTD built into the heater plate. The units are supplied with temperature calibration certificates traceable to NIST.

Temperature ramping up and down, count-down timer with alarm, user settable auto-off and RS232 I/O port are standard.

Various sample probes are available as accessories. The Model HP40A is available in 100, 115 and 230 VAC, 50/60 Hz models. All units are UL, CSA and CE certified.
