Description:
A sensitive amplifier is described which can be used, in conjunction with a milliammeter, to measure the low voltages encountered in thermocouple temperature measurements. It is much faster in response and more accurate than conventional bourdon tube type thermographs. The virtual absence of either the zero or sensitivity drift, so common in some types of d.c. amplifiers, and the use of battery power make it particularly useful for recording or indicating in remote locations where it must operate unattended.
