Product Overview
LASERGAS 12944-E is a laser gas analyzer developed by NEO Monitors.It is a core product of the LaserGas™III series.It uses tunable diode laser absorption spectroscopy technology(TDLAS),designed for high-precision gas detection in industrial environments.It is suitable for combustion control,safety monitoring and complex process analysis scenarios.
Core functions and technical parameters
1.Inspection principle and performance
Technical Basics:
Based on TDLAS technology,gas concentration is measured through a solid-state laser light source without contact,with high sensitivity and anti-interference ability.
Supports Baseline-Insensitive technology to enable high-precision measurements in complex gas mixtures,especially for combustion control and safety monitoring.
Detection of gas:
It may cover industrial gases such as HF(hydrogen fluoride),CO₂,CH₄,NOx(need to be determined according to the specific configuration).
Detection limit and range:
For example,the HF detection limit is 50 ppb(1m optical path),and the range can reach 0-500 ppm(specific parameters need to be configured according to the model).
Dynamic range:
It supports ultra-long optical path(such as 100m)and ultra-high concentration measurement,and is suitable for combustion furnaces,chemical reactors and other scenarios.
2.Hardware design
Structure and protection:
IP65 protection grade,adapts to dust,humidity and corrosive gases in industrial environments.
Compact and lightweight design,some models support portable or fixed installation.
Power and battery life:
Battery-powered models(such as Portable HF detectors)can operate continuously for about 10 hours(lithium-ion battery,14.4V 5Ah).
Fixed models support external power input.
Interface and communication:
Analog output(4-20 mA DC)and digital output(Modbus TCP/IP,RS-485),supporting industrial network integration.
Some models are equipped with an Ethernet interface for easy remote monitoring and maintenance.
3.Application scenarios
Combustion control:
Monitor gas concentrations during combustion(such as CO₂,CH₄)in real time,optimize combustion efficiency and reduce emissions.
Safety monitoring:
Detect leakage of toxic gases such as HF,trigger an alarm or link a safety system.
Process analysis:
In chemical,petroleum,electricity and other industries,it is used for gas composition analysis in reactors,pipelines and other scenarios.
Key Features
High precision and stability:
IROSS signal processing technology is adopted to improve measurement reliability under complex operating conditions.
Repeatability error as low as 1%full scale.
Modularity and scalability:
Supports simultaneous detection of multiple gases(multi-channel modules are required).
Combined with other models in the same series,such as LaserGas™III O,to form a complete analytical solution.
Low maintenance requirements:
No moving parts,reducing fault points.
It is recommended to calibrate every 12 months and replace the filter every 3 months.
