Evidence Notes
Confined-space oxygen verification for hot-work permit workflows
Application note based on the existing shipbuilding scenario: portable O₂ readings and logged records support standardized confined-space checks before hot-work release. Site timing depends on permit workflow, sampling practice, and record-retention requirements.

01 Measurement Principle and Limits
How the measurement is bounded
Electrochemical O₂ sensor for portable atmospheric testing and spot verification.
Requires
- Monthly bump test and six-month two-point calibration using ambient air and certified span gas
- Electrochemical sensor replacement per stated service life and site use pattern
Interferents and Limits
- Portable field verification duty; continuous process sampling is not declared in the v1 source data
- IP67 rating covers temporary immersion conditions stated in the FAQ, not continuous underwater service
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Operation outside the stated ambient range
- Continuous immersion beyond the stated IP67 temporary-submersion condition
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- electrochemical O₂ sensor
- audible and visual alarm thresholds
- USB-C data export
- No extractive conditioning system is declared for this portable SKU
04 Calibration & Validation
Calibration method, interval, traceability, and audit support are shown only when structured data is available.
Zero / Span Method
Two-point calibration via on-screen menu using ambient air and certified span gas
Interval
Monthly bump test; full two-point calibration every 6 months
Span Gas Traceability
Certified span gas required
05 I/O & Integration

DAHS Review Note
Confirm protocol map, channel naming, alarm states, and reporting format during project integration review.
06 Maintenance & Spares site-specific
Tasks, consumables, and access items are shown only when structured maintenance data is available.
- Monthly bump test
- Two-point calibration every 6 months
- Electrochemical O₂ sensor replacement per stated service life
- Field-replaceable electrochemical O₂ sensor
- Certified span gas
Cell Life
Typically 2 years under normal use
Service Access
Sensor cap access described in FAQ
07 Application Evidence
Reviewed application context for engineering selection.
Application Context
Shipyards running 200+ confined-space entries per day need rapid O₂ verification, but manual sampling with grab tubes adds 15+ minutes per space and pulls senior welders off the critical path.
Architecture Response
GS8110-O2 portable units with immediate digital readings shorten verification to under 3 minutes per space, supporting standardized hot-work permit workflows across multi-shift fabrication shops.
Frequently Asked Questions
How long does the electrochemical sensor last?
The electrochemical O₂ sensor typically lasts 2 years under normal use. It is field-replaceable in under 2 minutes by unscrewing the sensor cap and installing the new cell. A post-replacement bump test or span check should be planned by site procedure.
What does IP67 mean in practice?
IP67 means the GS8110-O2 is fully protected against dust ingress and can withstand temporary submersion in water up to 1 meter depth for 30 minutes. It is designed for the harshest field environments.
How often does the GS8110-O2 need calibration?
A monthly bump test (quick exposure to known gas) is recommended to verify sensor response, with a full two-point calibration every 6 months. Calibration is performed via the on-screen menu using ambient air and a certified span gas.
Can I export logged data to a PC?
Yes. Connect the GS8110-O2 via USB-C to your PC and use the included GasView software to download, graph, and export all 10,000 stored readings in CSV or PDF format.
Is the GS8110-O2 suitable for confined space entry?
Yes. The GS8110-O2 meets OSHA 1910.146 requirements for atmospheric testing during confined space entry. It provides continuous real-time O₂ readings with audible and visual alarms at user-configurable thresholds (default: 19.5% low, 23.5% high).
