ZyAura ZG9 Operating Instructions

Handheld Multi Gas Detector Operating Instructions
Model: ZG9
Product Overview
Thank you for selecting ZG9 handheld multi gas detector. The ZG9 is designed to simultaneously measure
multiple gas concentrations in the ambient environment. With long-term data storage, the user can assess the
environmental friendliness. When ZG9 measures the gas concentration reaching the alarm setting or higher,
the data display and alarm functions are activated. ZG9 is equipped with an RS485 interface for connecting to
a computer for remote monitoring so as to reduce the risk of exposure to high concentrations of harmful
gases and avoid harm to human health. ZG9 can be used in a wide range of industries, which include
paint-related industries, wineries, related industries of CO2, food industry, laboratory, construction industry,
etc.
Features:
□ V Dual beam NDIR (Non-Dispersive-Infrared) technology is used to measure CO
improve the long term stability.
□ V Measure CO , CO, VOC, PM2.5, PM10, RH, DP, AMB, Barometer
2
□ V Large LCD for easy reading of gas concentration and temperature and humidity.
□ V Audible alarm
□ V Data logging with SD card
□ V Through the RS485 interface connection, multiple ZG9 units can be connected to the back-end computer
system as a security monitoring application.
□ V Built in the LCD backlight for easy reading in the dark.
□ V This device is supplied with Li- ion 18650 3.7V rechargeable batteries, can be used for a long time.
