The enthusiastic reception and the splendid performance ofthe Welch Direct Current Meters of Commercial Quality, butdesigned especially for schools has led to the development of anew Alternating Current Meter of Commercial Grade for schoollaboratories. We are pleased to announce quantity production anda consequent price reduction in Welch alternating currentmeters. Some of the special features and characteristics of thenew Welch Alternating Current
