DS-RF

Selective Formaldehyde Module

DS-RF selective formaldehyde module can detect HCHO, VOC, TVOC, t & RH at the same time. The module combines selective HCHO sensor with advanced electronic control technology, converting HCHO concentration into PPM directly. The module realizes the detection of VOC and TVOC based on fuel cell technology. DS-RF selective HCHO module is free from the influence of the interference gases, such as C2H5OH, C6H6, NH3, CO, etc. DS-RF selective HCHO module is pre-calibrated in the factory and can be integrated into your system directly.
