Mechanical protection, compact integration, stable operation and simple handling are equally important in everyday laboratory and industrial environments.
RITTER MultiGas Sensors are designed to provide:
- compact and practical operation,
- reliable signal acquisition,
- straightforward system integration,
- and convenient deployment in research and process applications.
This allows users to integrate proven gas analysis technology into their workflows with minimal complexity.
Proven NDIR and NDUV Measurement Technologies
Depending on the application and target gases, RITTER MultiGas Sensors utilize established NDIR and NDUV photometric measurement principles.
NDIR Technology
NDIR technology is widely used for reliable monitoring of infrared-active gases such as:
- CO₂
- CH₄
- hydrocarbons
- and many common process gases.
Advantages include:
- stable long-term operation,
- low maintenance,
- non-consumptive measurement,
- and reliable performance in continuous applications.
NDUV Technology
NDUV technology enables selective measurement of ultraviolet-active gases and demanding analytical applications, including:
- O₃
- SO₂
- H₂S
- NO₂
- NO
- Cl₂
- and other specialized gas components.
NDUV systems are especially valuable where:
- selective gas detection,
- low concentration measurement,
- or complex gas mixtures
are required.
