Need to replace an Altek Voltage Calibrator?
Altek was the world leader in voltage calibrators but has discontinued manufacturing all products. PIE voltage calibrators, designed by the same engineer as the Altek models, are the ideal replacement! With even smaller size, similar functions, updated designs and value added features including patented current leak detection(milliamp models), rubber boots and backlit displays.
