NORTHDOME - SMART MONITORING OF GAS DENSITY

NORTHDOME is a unique patented sensor to monitor gas density, specific gravity, pressure, temperature and average molecular weight in real time. NORTHDOME is ideal to be embedded in all kind of OEM applications. Don’t wait any longer to enhance your analyzers properties, check our full list of applications.

SMALL & SMART

NORTHDOME is the smallest integrated gas density and temperature meter on the market. With its small footprint, it is ideal for OEM applications, such as being embedded into gas analyzers or gas metering systems.

MESOSCALE PATENTED TECHNOLOGY

The patented MESOSCALE all metal construction provides unrivalled ruggedness, sensitivity, integrity and dynamic response to changes in the gas composition. MESOSCALE  design is used to miniaturize the sensing element to less than 1 cc. The result is a simple flow path, making NORTHDOME easy to apply and tolerant to particles and material deposition

DYNAMIC BEHAVIOR AND ROBUSTNESS

NORTHDOME is factory calibrated and certified for use in hazardous areas. The wetted materials offer a high corrosion resistance It can be applied in wide range of gas flows, from static conditions to mainstreams. NORTHDOME is virtually maintenance free, no specific recalibration routine is required.
