Gas Sensor Calibration Kits and Test Gases for Marine and Offshore Safety
Ftron Technology – Global Expertise in Gas Detection and Calibration Solutions
Introduction
The marine and offshore industry operates in an environment where safety is paramount. Enclosed spaces, engine rooms, cargo tanks, and pump rooms all carry the risk of hazardous gases such as carbon monoxide, hydrogen sulfide, methane, and oxygen depletion. Reliable gas detection systems are therefore critical for safeguarding lives, assets, and the environment.
However, gas sensors are only effective when regularly calibrated and tested using certified calibration kits and test gases. Without proper calibration, even the most advanced detectors can provide false readings – potentially leading to catastrophic consequences.
At Ftron Technology, we bring decades of expertise in supplying, commissioning, and maintaining gas sensor calibration kits and certified test gases. Working globally with our network of channel partners and experienced marine engineers, we provide tailored solutions for ships, offshore platforms, and industrial plants.
Importance of Gas Sensor Calibration
Gas detectors, whether portable or fixed, tend to drift over time due to:
Environmental conditions (temperature, humidity, salinity).
Sensor aging and degradation.
Exposure to high gas concentrations.
Contaminants (oil vapors, dust, chemicals).
Calibration is vital because:
It ensures accuracy of gas concentration measurements.
It keeps detectors in compliance with IMO, SOLAS, and ISO requirements.
It prevents false alarms or undetected hazards.
It extends sensor lifespan and reliability.
It is often required during Class inspections, PSC checks, and ISM audits.
Regulatory Framework
Marine safety authorities mandate calibration of gas sensors at defined intervals.
IMO SOLAS Chapter II-2 Regulation 4.5.7 – Requires portable gas detection equipment onboard.
SOLAS Chapter XI-1 Regulation 7 – Calibration and testing of detectors for enclosed space entry.
IMO MSC.1/Circ. 1621 – Guidelines for onboard portable atmosphere testing instruments.
IEC 60079 Series – Standards for explosive atmosphere detection equipment.
ISO 9001 & ISO 14001 – Quality and environmental standards for calibration gases.
Class Society Rules (ABS, DNV, LR, BV, RINA, CCS) – Define calibration and testing requirements.
Components of Gas Sensor Calibration Kits
A standard gas sensor calibration kit usually includes:
Calibration Gas Cylinder – Pre-mixed certified test gas with specific concentration.
Regulator – Flow regulator or demand flow regulator to control gas release.
Tubing & Connectors – Marine-grade flexible hoses for gas transfer.
Calibration Adaptor / Cap – Fits securely on the detector’s sensor head.
Carrying Case – Rugged marine-proof case for portability.
Test Gases for Marine Applications
The choice of test gas depends on the type of sensor. Common gases include:
Carbon Monoxide (CO) – For engine room, galley, and accommodation monitoring.
Oxygen (O₂) – For confined space entry and enclosed space testing.
Hydrogen Sulfide (H₂S) – For crude oil tankers and chemical carriers.
Methane (CH₄) / Combustible Gases – For LNG carriers and engine spaces.
Carbon Dioxide (CO₂) – For cargo holds and fire suppression systems.
Sulfur Dioxide (SO₂) – For monitoring exhaust gas cleaning systems (scrubbers).
Nitrogen Oxides (NO / NO₂) – For emissions monitoring.
Ammonia (NH₃) – For refrigeration plants and ammonia carriers.
Cylinder Sizes Available:
34L (portable, short calibration tasks).
58L (standard portable calibration gas).
110L, 116L (extended use).
550L (long-term, multiple calibration cycles).
Types of Calibration
Bump Test
Quick functional test.
Detector is briefly exposed to test gas.
Verifies sensor response and alarm functionality.
Full Calibration
Detector is exposed to known gas concentration.
Sensor is adjusted to match reference gas.
Ensures measurement accuracy.
Frequency:
Portable detectors – before each use or weekly bump test, full calibration every 3–6 months.
Fixed detectors – at least every 6 months (as per manufacturer recommendation).
