Abstract

Coulometric Thickness Meter. Based on a design by the British Non‐Ferrous Metals Research Association, a plating meter for accurately measuring the thickness of most industrial platings has been manufactured by Nash & Thompson Ltd. The coulometric principle which involves stripping the plating from a standard area and measuring the integration of time and current density normally occupies only a few minutes and the meter switches itself off when the stripping action is completed. The thickness of the plating thus removed is determined from a dial reading and a multiplying factor. Readings between 0.000004 in. and 0.0015 in. can be made to an accuracy of ±5%. The meter is mains operated with transistorised circuits. CT 1168
