Trace analyzer O2Tracer

oxygenmonitoringprocess

Overview
The O₂ Tracer is a compact analyzer for measuring oxygen concentration from trace ppm levels up to percent values using an electrochemical fuel-cell sensor. It is intended for industrial gas monitoring and process control.

Overview Table

• Parameters: Oxygen %, Oxygen ppm
• Method: electrochemical (fuel cell)
• ATEX: No
• SIL: No
• Range: 0 – 100 %; 0 – 25 %; 0 – 5 %; custom ranges
• Accuracy: ±5 % FSD
• Response time T90: 10 s
• Output: 4 – 20 mA
• Supply Voltage: 10 – 35 V

Description
The instrument provides straightforward measurement and readout of oxygen concentration with a clear LCD and bargraph. It is designed for integration into industrial installations where compact size and basic transmitter functionality are required.

One user specific measuring range
The unit can be configured with a single user-defined measuring range within 0–100 % O₂ to match specific process requirements.

Sensor
The O₂ Tracer employs an electrochemical fuel cell sensor optimized for oxygen measurement. The sensor offers industry-appropriate sensitivity, stability and a long operating life under normal conditions.

Calibration
Calibration for trace oxygen measurements should be performed using a calibration gas at a chosen concentration within the selected measuring range. For percent-range calibration, ambient air may be used.
