SO₂ MEZUS 110 Analyzer

Monitoring of Sulfur Dioxide using UV Fluorescence

TheMEZUS 110is a high-precision analyzer designed to measure the concentration of sulfur dioxide (SO₂) in ambient air. Using the advanced method ofUltraviolet Fluorescence (UVF), this equipment is capable of detecting minimal traces generated by industrial combustion processes and refining. Its robust architecture and high-performance processor make it the ideal solution for air quality monitoring networks that demand stability and operational accuracy.

Why choose the MEZUS 110?

Ultra-Sensitive Detection:Thanks to its lower detection limit of0.4 ppb, the MEZUS 110 captures minimal variations in air quality with exceptional accuracy.
Guaranteed Stability:With zero drift and minimal span (less than 0.5% in 24h), the equipment reduces the need for constant calibrations, ensuring the reliability of historical data.
Intelligent Data Management:Its internal memory stores up toone year of measurements(5-minute averages) along with operation histories and alerts, facilitating audits and environmental reports.

Features:

Measurement Method:Ultraviolet Fluorescence (UVF).
Selectable Ranges:0 - 0.1 / 0.5 / 1 / 20 ppm.
Response Time:Less than 100 seconds (T95).
Linearity and Repeatability:±1% and ±0.5% of full scale respectively.
Sample Flow:Stabilized control through a critical orifice of 700 cc/min.
Interface and Communications:7-inch LCD graphic display with Ethernet, USB, RS-232C, and RS-485 ports.
Analog Outputs:0-5V, 0-1V, and 4-20mA option for integration with PLC/SCADA.
Integrated Filtration:47 mm Teflon filter for protection of the optical chamber.

1. How often should the equipment be calibrated?

To ensure maximum accuracy, it is recommended to perform a verification ofZero and Spanweekly. However, due to its low drift, full calibration can be scheduled monthly or as required by local air quality regulations.

2. What standard gas is required for calibration?

The equipment uses standard gas cylinders ofSulfur Dioxide (SO₂)diluted in nitrogen (N₂). It is essential that the gases have traceability certification to ensure that the span parameters match the ranges selected in the analyzer.

3. What is the function of the 47mm Teflon filter?

This filter is critical for protecting the UV fluorescence chamber from particles and environmental dust. It is recommended to visually inspect it every 15 days and replace it if there are color changes or dirt accumulation to avoid drops in sample flow.
