A p-type metal oxide VOC sensorVOC-A31 M31 P31Product Introduction

This sensor is for broadband total volatile organic compounds（Total VOC）Detector. When consideringPIDWhen it comes to cost issues, this sensor can be used to detect them10~50ppbofVOCDepending on the specific situationVOCTypes. Compared to commonnDifferent types of sensors, this metal oxide sensor has a large dynamic range, repeatable response, is less affected by humidity, and encounters most challengesVOCThe resistance will increase.
