Product Description
Introduction
Based on the infrared absorption of gas molecule, GNL-5000 uses the innovative NDIR technology, such as digital pulsed infrared source, high sensitive infrared sensor. It can be used for detection for different concentration and different gases (SO2, NOX, CO2, CO, CH4, etc).
Features
Special cell absorber and narrow filter slice with strong anti-jamming and high precision
High stability for infrared source, constant temperature for controlling receiver
Measuring cell with gilded mirror can be corrosive-resistance.
Large LCD display
0/4-20mA signal output
Setting upper and lower alarm values arbitrarily during the measurement range
Timing automatic storage function, which you can check store data at will;
Applications
It can be used in petroleum, chemical process, fertilizer, air separation plant, metallurgy, building materials, power factory, medical factory, environmental protection, scientific research, and other areas.
