The present invention relates to a device and method for providing precise temperature control using inexpensive temperature controllers and/or thermostats. Specifically the invention provides modifications to either a temperature controller and/or a thermostat that enables precise temperature control using inexpensive components. The series rheostat type differential eliminator (SRDE) is an inexpensive circuit that interfaces between a temperature controller and a thermistor or other temperature sensor element. The SRDE is essentially a circuit that swi...
1. A temperature control circuit, said temperature control circuit comprising:a temperature controller having multiple inputs and a temperature differential;a rheostat;a shunt; anda thermistor responsive to temperature and having multiple lead wires,wherein one thermistor lead wire is connected to a first temperature controller input and a second thermistor lead wire is connected to a second temperature controller input by a switching means that selectively switches said rheostat or said shunt in series between said second thermistor lead wire and said s...
