Description: 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.
