Product Description

The 616KD series differential pressure transmitter adopts One-Touch? one-button digital calibration technology, which is simple in design
Easy installation and maintenance. Ideal for professionals. Instead of using the conventional potentiometer method for zero adjustment and calibration, the one-button calibration technology of the word button chain is adopted, so that both the zero and the range are calibrated immediately, without any other calibration equipment and tools. There is also no need for a pressure source for calibration.
