Abstract

In Dobson Ozone Spectrophotometer, the amplified a.c. component of the photomultiplier output is rectified by means of a rotating commutator for indication in the meter. An attempt has been made to replace this mechanical rectifying device by means of a simple crystal diode circuit with satisfactory results. With this, a sharp minimum in current value, and not a reversal of the meter current, indicates null point. Studies have been made to see its workability in different spheres of spectorphotometer operation.
