JNYQ-I-41 High-Quality Professional SO₂ Gas Analyzer

Product Introduction

The JNYQ-I-41 SO₂ Gas Analyzer is an infrared gas analysis instrument designed for sulfur dioxide (SO₂) measurement in environmental monitoring, industrial process control, and laboratory applications. It uses non-dispersive infrared (NDIR) technology to analyze gas concentration and provides digital signal processing for stable, linearized measurement output.

With multiple signal and alarm options, selectable RS232 or RS485 communication, and compatibility with integrated multi-gas systems, the JNYQ-I-41 supports continuous gas monitoring in suitable applications. It can be used for atmospheric pollution monitoring, industrial emissions analysis, petroleum and chemical processes, and public air quality monitoring.

2. Advanced Digital Processing: Processes measurement signals digitally to support reliable concentration readings.

3. Linearized Output: Provides linearized measurement output for monitoring and control systems.

4. Multiple Alarm and Signal Options: Supports sound, light, visual indication, relay, and message-based alerts, depending on configuration.

5. Multi-Gas System Integration: Can be combined with compatible gas analyzers under the same operating conditions, supporting up to four groups in one instrument system.

6. Flexible Communication: Selectable RS232 or RS485 communication interfaces.

7. Analog Current Output: Supports selectable 0–20 mA or 4–20 mA output with a specified load of 500 Ω.

8.  Upper and Lower Limit Control: Provides passive contact outputs for upper- and lower-limit alarm control.

Working Principle

The JNYQ-I-41 uses the non-dispersive infrared (NDIR) principle to measure sulfur dioxide concentration. SO₂ absorbs infrared radiation at characteristic wavelengths. The analyzer measures the change in infrared energy passing through the gas sample and uses the relationship between absorption and gas concentration to calculate the SO₂ level.

The resulting signal is processed digitally and converted into a linearized concentration output. Alarm and communication functions can transmit measurement information or alert signals to compatible monitoring and control systems.
