Product Specification
NAP-56A is not made with thermoplastics to achieve a higher temperature resistivity. The pin locations and dimensions are compatible to NAP-55A for the convenience of current users of Nemoto NAP-55A. The gas sensitivity is better than NAP-55A by about 15%. Users are to pay attention to this higher gas sensitivity upon calibration.
