Adaptater for thermometer

It can be very useful to have a voltage available that varies in proportion with temperature : just think about computerised or non-computerised control systems, temperature monitoring, or simply a digital (or analogue) thermometer. The zero point is adjustable over a wide range and does not necessarily have to be zero volts for zero degrees. The output is buffered and can be connected directly to an analogue or digital millivoltmeter, such as kit K2032 or an ordinary multimeter.
