About this item:
Range:0-50ppm
Resolution:0.1ppm
L-alarm:5ppm ; H-alarm:10ppm
Output current:4-20mA
It is used to detect the concentration of flammable gas or other toxic and harmful gases in the air. When the concentration reaches or exceeds the preset alarm value, the controller will sound and light an alarm to promptly remind to take safety measures to prevent explosion and poisoning accidents, so as to protect life and property.
Features:
Advanced MCU control with low power consumption;
Adjustable low and high alarm level;
Adjustable calibrating level;
High concentration protection for combustible gas;
Self test for the combustible gas sensor;
Low battery indication;
Self-adjustment function
Visual and audible alarm with vibration;
Advanced self-examination and self-renovation function
Password management to avoid wrong operation;
Explosive proof housing.
