MT220 Digital Manometer
Brand: Yokogawa Electric CorporationThe MT220 can measure pressure with outstanding accuracy, high resolution, minimal tempo, and excellent stability.
It offers a wealth of functions for field calibration, including transmitter output measurement (DCV/DCA functions), 24 Vdc output, percent error readout, measurement data memory, and Ni-Cd battery operation.
The D/A conversion output makes it simple to output data to a recorder or other equipment. And of course, data output through a GP-IB or RS-232 interface is also possible-including data output during operation on a 12 Vdc power supply or Ni-Cd batteries.
Features- High Accuracy: ±0.02% of Reading, with a Maximum Allowable Input of 500 kPa (130 kPa Range Model)
