Calibration Services
The SOLAS XI-1/7 regulation requires gas detectors to be dedicated 4-gas portables (not personal), capable of 10 hours continuous operation, waterproof and dustproof to Ingress Protection rating IP67, and capable of remote detection (using a pump with a sample hose) suitable to test the atmosphere in an enclosed space before entry. Calibration is also a requirement, as prescribed by the manufacturers’ instructions. We recommend as best practice to bump test and/or calibrate as frequently as is practical on-board the vessel.
For calibration on-board ship our engineers are available at 24/7. We are providing calibration services to the following listed below products as follows:
- Analogue Pressure Gauges
- Digital Pressure Gauges
- Digital Pressure Indicators
- Vacuum Gauges
- Pressure Transmitters
- Thermocouple Probes
- Thermocouple Indicators
- Thermocouple Simulators
- Resistance Probes
- RTD Indicators
- Liquid-in-glass Thermometers
- Digital Thermometers
- Pressure Manometers
- Pressure Transducers
- Temperature Calibrators
- Resistance Thermometer (RTDs)
Types of Gas Detection Meters for Ships
1. Combustible Gas Indicators or Explosimeters
An explosimeter is a device used to detect the amount of combustible gases present in a sample of the given atmosphere. This gives the reading in terms of percentage of the LFL (lower flammable limit).
2. Tankscope or Non-combustible Gas Indicator
A Tankscope® is a device used for measurement of hydrocarbon gas content in a sample of given atmosphere. This instrument is meant for measuring the hydrocarbon vapor in inerted atmospheres. This instrument is not as sensitive as the explosimeter. The reading is only in percentage of the volume of the hydrocarbon vapor and hence used only during the gassing up operations and during inerting. This is purely meant for measuring the volume of the hydrocarbon vapors present inside any enclosed space, and hence it is not meant for measuring during a man-entry.
3. Multi-Gas Analyzers
Multi-gas analyzers are used to detect only targeted gases and vapors. It is very specific to that type of gas only, so care has to be taken to ensure that correct tubes are used for the particular type of gas.
4. Oxygen Analyzers
The oxygen analyzer is a device used to measure the concentration of oxygen in a given atmosphere. This device plays a vital role since with the reading provided, only man-entry is done. The important checks that are done on the oxygen analyzers are: Calibration with fresh air (which contains 21% of oxygen) Battery check Never change the batteries in a gas dangerous zone.
