More Information

Fluke 2640A NetDAQ Data Acquisition Unit gives you a powerful combination of hardware and software that’s ideal for small-to-medium scale process monitoring and test systems

They answer the escalating need for measurement, recording, and analysis tools that enable you to improve quality, maximize process efficiency and meet regulatory requirements. Building blocks of 20 channels can be expanded into integrated systems of up to 400 channels. Choose between two models for speed up to 1000 rps and accuracy up to 0.01%.

All NetDAQs utilize Fluke’s patented Universal Input Module which accepts any combination of analog input types for each of its 20 channels – without the need for external signal conditioning. Simply pre-wire the Universal Input Module to directly measure temperature, dc volts, ac volts, resistance, 4-20 mA, and frequency.
