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.
