Product Details
The Integra TL 1 is a UK manufactured, three phase meter that is used with Crompton Instruments' 3-in-1 Current Transformers. Ideal for low voltage applications, the meter can measure multiple single and three phase loads for a cost effective solution, however, the option to measure individual loads can be programmed onto the unit when required. The Integra TL 1 also features an integrated microprocessor for exceptional waveform handling.
