Product Introduction

The ZHK-2018 portable multi gas analyzer is a rapid detection instrument used by our company for toxic and harmful gases in the ambient air. The equipment adopts measurement methods such as electrochemical, non dispersive infrared (NDIR), photoionization (MEMS-PID), etc. according to the different components being measured to measure the gas concentration in the ambient air. It is used to measure the concentration of harmful and pollutants in the atmospheric air and is suitable for environmental and health monitoring. It has the advantages of high measurement accuracy, long service life, and low cross interference. It is a necessary instrument in the field of environmental monitoring. Its main application areas are air quality monitoring in various industrial health protection zones; Industrial environment control; environmental protection.
