WZ-H3-NK

Selective High Temperature Resistant Formaldehyde 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℃. 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 in the factory and can be integrated into your system directly.
