Oxygen analyzers are vital instruments used to measure and control oxygen concentration within combustion, exhaust, and inert gas systems. Accurate calibration of these sensors is essential for safety, efficiency, and regulatory compliance. At Thermo-Tech, we provide O₂ analyzer calibration and set adjustment services for marine and industrial applications — ensuring reliable performance and precise oxygen monitoring under all operating conditions.
Our calibration procedures are performed using certified calibration gases and reference instruments traceable to international standards. Each analyzer is tested for sensor accuracy, drift, and response time, followed by fine-tuning of set points and alarm thresholds according to system design requirements.
Thermo-Tech’s service engineers perform both onboard and workshop calibrations, ensuring compliance with IMO, SOLAS, BV, and DNV standards. The result is precise oxygen control that safeguards against combustion inefficiency, incomplete gas inerting, and potential explosion risks.

Our O₂ Analyzer Calibration Services cover equipment used in boilers, IGG/IGS systems, incinerators, and exhaust gas scrubbers. We check and adjust signal outputs, replace worn sensors, and recalibrate control panels for accurate data transmission.
Each calibration includes verification of analyzer linearity, span gas accuracy, and automatic zero-point correction to ensure the system responds correctly under real load conditions.
In addition to calibration, Thermo-Tech provides O₂ analyzer maintenance and refurbishment services, including probe cleaning, sensor replacement, and electronics testing. When required, we perform PLC integration and data logging setup to enable remote monitoring and trend analysis of oxygen readings.
Our team issues calibration certificates, complete with test results and traceability records, to ensure full compliance with class society and audit requirements.
Thermo-Tech’s O₂ Analyzer Calibration and Set Adjustment Services guarantee accuracy, safety, and reliability across all combustion and inert gas systems.
By combining advanced testing methods, certified instrumentation, and expert field service, we ensure every analyzer operates within precise parameters — protecting your systems and maintaining compliance.
