Hydrogen Gas Analyzers II MP

NEO Monitors AS

Fast response time
No interference from background gases
Reliable trace level gas measurement
Precise optimisation of your process
Turn-key instrument

The Hydrogen Gas II MP is a gas monitor utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS), a contactless optical measurement technique. It offers fast response time, very low detection limits (ppb for many gases), no interference from background gases, long-term calibration stability, and no zero drift.
It is designed for applications in the chemical, petrochemical, and semiconductor industries, among others, and provides reliable trace-level gas measurement with high performance and low maintenance. The monitor is a self-contained unit requiring connection of power, sample gas inlet/outlet, and purge gas (application dependent).
It is designed to work with a suitable sample conditioning system to ensure a clean and dry sample is delivered to the MP cell. The LaserGas™ II MP features a multipass configuration where the laser beam is coupled into a Herriott cell, creating a long optical path that enhances measurement sensitivity.
It is certified for ATEX and CSA, ensuring safety in hazardous environments. The monitor has a compact design, is easy to install and operate, and requires minimal maintenance, providing an excellent return on investment.

Use Cases

Chemical industry
Petrochemical industry contaminants monitoring
Natural gas treatment (sweetening plants; H2S in NG)
Industrial gas (impurities in pure gases)
Semiconductor industry trace impurity measurements
Power plants (stack testing of corrosive emission gases)
H₂S emission monitoring (pulp & paper, refineries, biogas production)
Hydrogen impurity

Capabilities

Contactless, in-situ/inline trace gas measurement using TDLAS with multipass optical path for high sensitivity
Stable long-term operation with no zero drift and extended calibration intervals (up to 12 months)
Operation in hazardous areas (ATEX/IECEx Zone 2; CSA Class I, Div 2)
Flexible integration via 4–20 mA and digital communications (TCP/IP, MODBUS; fibre optic optional)
