Electrochemical Formaldehyde Sensor KGD - HCHO - 103
Product Introduction
The KGD - HCHO - 103, the fourth-generation formaldehyde sensor, is a gas concentration sensor based on the electrochemical principle. It adopts a dual-channel structural design, combined with a unique electrolyte packaging technology. Through mathematical algorithms and scientific multi-point calibration, it enables the simultaneous output of formaldehyde, VOC, and TVOC. With a built-in temperature and humidity digital sensor, and combined with intelligent algorithms, the product provides more accurate detection and more convenient application.
