The Ashcroft AM2-1 low pressure module and AM2-2 medium/high pressure module are interchangeable sensor modules for the Ashcroft ATE-2 digital calibrator.
The AM2-1 ranges from 0.25 to 200 inches H20 and the accuracies is from ±0.1% to ±0.06% of span. The AM2-1 sensor is really tough and it can withstand compelling overpressure, shock, and vibration without huge errors or calibration offset.
