HP-3040 is a precision hot plate with a larger heating area ( 15"x11")  and a digital temperature controller, which is designed to mount the crystal samples on the polishing machine by wax. It is also useful for precision heating of all kinds of chemicals.

SPECIFICATIONS:

Features	Digital temperature control from 35 °C - 2000 °C with +/- 1 °C accuracy. Extra flat surface, which is ideal for flat substrate wax mounting before polishing. Excellent for heating and mounting brittle crystal materials at a uniform temperature. Aluminum plate for more even temperature distribution.  Detachable heating plate for easy maintenance.
Model	3040
Power supply	AC 220V, 5/60 Hz
Power	1200 W
Max. Temperature	200 °C (392 °F) Max.
Temperature Control	PID controller with +/- 1 ºC accuracy
Heating Area	373 x 273 mm (14.7" x 10.7")
Temperature Measurement	PT100 (Resistant temperature detector) Unlike thermocouples, it is not necessary to use special cables to connect to the sensor. The principle of operation is to measure the resistance of a platinum element. The most common type (PT100) has a resistance of 100 ohms at 0 °C and 138.4 ohms at 100 °C.
