OMS420 – O2 & COe In situ real-time analyzer
Real-time oxygen and COe analysis on site
The MRU OMS 420 is an in-situ gas analyzer designed for real-time measurement of oxygen (O₂) and carbon monoxide equivalent (COe) in industrial combustion processes such as boilers. It enables continuous combustion optimization and energy efficiency improvements, supporting process temperatures of up to 1,700 °C (depending on the model).
Key Features :
-
Continuous on-site measurement of O₂ and COe without sample extraction.
-
Multiple configurations available: Compact, High-Temperature (HT), and Remote Transmitter (RT) models.
-
High-accuracy zirconium dioxide (ZrO₂) sensor with fast response time (<10 seconds).
-
Dual analog outputs (4–20 mA) and digital output (RS485, Modbus RTU).
-
Rugged aluminum die-cast housing, rated IP65 for industrial environments.
-
Options for automatic calibration and compressed air back-purge, ideal for dusty environments.
-
Service-friendly design: quick replacement of the transmitter module by removing only four screws.
Measurement Ranges :
-
Oxygen (O₂): 0.1 – 25.00 %, with accuracy of ±0.2% or ±5% of reading.
-
COe: 0 – 1,000 ppm, with accuracy of ±50 ppm or ±10% of reading.
This product is ideal for heavy industrial applications such as cement plants, power generation facilities, and refineries, and is also available in an Ex-version for hazardous area (Zone 2) applications.
