Series 616KD-LR Differential Pressure Transmitter - Low Ranges

High Accuracy, Ranges Down to 0.1 in w.c. (25 Pa)

The SERIES 616KD-LR Differential Pressure Transmitter is designed for simplicity, making it the ideal choice for installers and maintenance professionals. These low range instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instruments during calibration. With single digital push button, both ZERO AND SPAN are calibrated properly, nothing else is required. No additional reference pressure sources or separate calibration devices are necessary.
