Evidence Notes
Portable SO₂/NOₓ screening workflow before reference-method testing
Application note based on the existing environmental-consulting scenario: portable electrochemical SO₂/NOₓ measurement supports field screening, commissioning checks, and audit preparation before a formal CEMS or reference-method campaign is selected.

01 Measurement Principle and Limits
How the measurement is bounded
Dual electrochemical sensors measure SO₂ and NOₓ for portable spot checks and maintenance diagnostics.
Requires
- Replaceable SO₂ and NOₓ sensor cartridges
- Operation within stated ambient temperature and non-condensing humidity limits
- SD card workflow when CSV records are needed
Interferents and Limits
- High humidity or condensation outside the stated 15-90% RH non-condensing boundary
- Operation outside the stated -10°C to +50°C operating temperature range
- Formal compliance reporting that requires certified reference-method or QAL1 CEMS testing
02 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Condensing stack sample at the sensor inlet
- Use as certified reference-method testing equipment
03 Sample System Boundary
Sampling mode, conditioning components, and exclusions define where the analyzer responsibility ends and the sample system begins.
- portable analyzer with pump
- K-type thermocouple input
- SD card data storage
- No external extractive conditioning system is declared for this portable SKU
- Dedicated SO₂/NOₓ configuration only; additional gas sensors are not supported

06 Maintenance & Spares site-specific
Tasks, consumables, and access items are shown only when structured maintenance data is available.
- Replace SO₂ and NOₓ electrochemical sensor cartridges at the stated service-life interval
- Use the user-replaceable cartridge workflow stated in v1 FAQ for field maintenance
- Keep SD card records available for survey handoff when field data export is required
- SO₂ sensor cartridge
- NOₓ sensor cartridge
Cell Life
SO₂ sensor: 18-24 months typical; NOₓ sensor: 24-36 months typical
07 Application Evidence
Application context from complex industrial environments.
Application Context
Environmental-consulting firms running SO₂/NOₓ spot checks at 100+ industrial sites annually face mobilization burden when each assessment requires a 2-day CEMS setup before any go/no-go decision.
Architecture Response
GS8210-EC portable analyzers let 2-person field teams pre-screen sites in 30 minutes, so sites passing screening avoid the upstream CEMS mobilization while sites that fail get prioritized for full reference-method testing.
Frequently Asked Questions
How often should I replace the electrochemical sensors?
SO₂ sensor: 18–24 months typical. NOₓ sensor: 24–36 months. Both are user-replaceable cartridges — no factory service required.
Can I measure stack temperature simultaneously?
Yes, the built-in K-type thermocouple input displays stack temperature alongside SO₂/NOₓ readings, useful for emission calculations at reference conditions.
Is it accurate enough for compliance reporting?
The GS8210-EC is designed for screening and diagnostics, not certified reference method testing. For formal compliance, specify GS-CEMS-200 with QAL1 certification.
How does the SD card data export work?
Remove the SD card and insert into any PC. Data is stored as CSV with timestamp, gas readings, temperature, and GPS tag (if enabled).
Can I add additional gas sensors?
The GS8210-EC is a dedicated SO₂/NOₓ instrument. For multi-gas portable detection (O₂, LEL, CO, H₂S), see GS8610-4G.
