Operation manual for WZ-H3-NK HCHO Module WZ-H3-NK Selective & High Temperature Resistant Formaldehyde Module

& Operation manual for WZ-H3-NK HCHO Module WZ-H3-NK selective & high temperature resistant formaldehyde module is the one launched specially for application in cases where temperature is higher than 60 °C . WZ-H3-NK HCHO module is the first application of solid electrolyte integrated in fuel cell vehicles to HCHO detection —real solid electrolyte, free from electrolyte leakage or dry out; WZ-H3-NK selective HCHO module is free from the influence of the interference gases at low concentration, such as C2H5OH and can generate accurate detection result. WZ-H3-NK selective HCHO module is pre-calibrated...
