51 series Brochure

Product catalog summary

Overview: The document outlines the specifications and functionalities of the HORIBA 51 series gas analyzers, which include magnetopneumatic, paramagnetic, thermal conductivity, and infrared analyzers. These devices are designed for diverse gas analysis needs, emphasizing safety, reliability, and accuracy, especially in explosive environments.

Explosion-Proof Design: The analyzers are explosion-proof, compliant with IEC 60079 standards, suitable for flammable gases in groups IIB+H2 and IIC, with a temperature class of T4 (maximum surface temperature of 135℃). Protection types include flameproof enclosures and pressurized apparatus.

Technological Features: The 51 series features advanced technologies like interference correction in NDIR analysis for high accuracy, even with interfering compounds. The analyzers have a user-friendly interface with a clear display.

Measurement Principles:

Magnetopneumatic and Paramagnetic Analyzers: Use the strong paramagnetic properties of oxygen to measure concentration through changes in pressure or force in a magnetic field.
Thermal Conductivity Analyzers: Measure gas concentration based on differences in heat conductivity using a Wheatstone bridge configuration.
Infrared Analyzers: Use non-dispersive infrared technology with interference correction for accurate gas concentration measurement.

Specifications: The analyzers offer various measurement ranges and performance metrics, including repeatability and response time. They support digital connections via RS-485 and Modbus-RTU protocols, with options for analog output.

Applications: The 51 series is suitable for a wide range of applications, including general-purpose processes and specific models for oxygen and hydrogen analysis. Designed for indoor use, they have operational temperature and humidity constraints.

System Configuration: Details on system configuration include peripheral instruments required for pressurized apparatus and the layout of hazardous and non-hazardous areas.

Contact Information: The document lists contact details for HORIBA offices worldwide, emphasizing global availability and support for these analyzers.

Management Systems: HORIBA Group has adopted an Integrated Management System (IMS) combining ISO9001 for Quality Management, ISO14001 for Environmental Management, OHSAS18001 for Occupational Health and Safety, and ISO22301 for Business Continuity Management to ensure stable product and service delivery during emergencies.

infrared (NDIR) analyzer (interference correction type) Measurement principle Conceptual diagram Light source “Interference correction” is an original method based on NDIR analysis that ensures extremely high accuracy even in the case of samples containing large amounts of interfering compounds. The interference correction combines a measurement sensor with a correction sensor positioned in parallel in the same optical path. This significantly reduces the effects of: interfering gases in the sample gas; vibrations and other external disturbances; and drift resulting from deterioration of the...
