The Dwyer Instruments 616KD Differential Pressure Transmitter features one-touch digital push-button calibration technology and are designed for simplicity, making them the ideal choice for installers and maintenance professionals. These instruments not only alleviate cumbersome turn pots typically found in most transmitters, but eliminate entirely the need to span the instruments during calibration. With a 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.

Applications include air handlers, duct pressure, variable air volume, and filter monitoring.
