Correction By Zero Adjustment






Category: PYROMETRY AND PYROMETERS

Many pyrometers are supplied with
a zero adjuster, by means of which the pointer can be set to any
actual cold-junction temperature. If the cold junction of the
thermo-couple is in a temperature of 100 deg.F., the pointer can be
set to this point on the scale, and the readings of the instrument
will be correct.
