Forensics Sulfur Dioxide Analyzer — SO2 Gas Detector (0-20 ppm, Pump & Probe)

Forensics Sulfur Dioxide Analyzer — SO2 Gas Detector with Pump

The Forensics sulfur dioxide analyzer measures SO2 from 0-20 ppm with a built-in pump and 4 ft probe — the portable gas detector for refineries, pulp & paper and food processing, covering a toxic gas the four-gas set doesn’t. It ships NIST-calibrated.

The Forensics Sulfur Dioxide Analyzer is a handheld, NIST-calibrated SO2 gas detector (0-20 ppm) with a built-in pump and 4 ft probe for refinery, pulp-and-paper and food-processing use.

Key features

• Measures sulfur dioxide (SO2) from 0-20 ppm — a toxic gas outside the 4-gas set
• Built-in pump and 4 ft probe for remote sampling and surveys
• USA NIST-traceable calibration with certificate
• Audible, visual and vibration alarms
• USB-rechargeable for shift-long use
• For refineries, pulp & paper, food processing and combustion sources

Specifications

Where the Forensics Sulfur Dioxide Analyzer fits

• Refineries and combustion sources
• Pulp and paper mills
• Food and beverage (SO2 preservation)
• Metal smelting
• Leak surveys around SO2 sources

What the Forensics Sulfur Dioxide Analyzer detects (and what it doesn’t)

It detects sulfur dioxide (SO2) only — not O2, combustibles, CO or H2S. For the four atmospheric gases use a Forensics 4 Gas Meter; for other single toxics see the Ammonia or Chlorine analyzers. The low 0-20 ppm range suits SO2’s strict exposure limits. Bump-test with SO2 calibration gas and recalibrate on schedule.

• Choose the SO2 Analyzer for refineries, pulp & paper and combustion-source sulfur dioxide.
• For chlorine or ammonia, see the Chlorine and Ammonia analyzers.
• For the four atmospheric gases, use a 4 Gas Meter.

Frequently asked questions

What does the Forensics SO2 analyzer measure?

Sulfur dioxide (SO2) from 0-20 ppm. It does not measure O2, LEL, CO or H2S — use a 4 gas meter for those.

Why is the range only 0-20 ppm?

SO2 has strict exposure limits, so a low, high-resolution range is appropriate for monitoring around the relevant ppm levels.

Does it have a pump?

Yes — a built-in pump and 4 ft probe let you sample remotely and survey for SO2 sources.

Where is an SO2 detector used?

Refineries and combustion sources, pulp and paper mills, metal smelting, and food/beverage operations that use SO2 as a preservative.

Is it NIST calibrated?

Yes — USA NIST-traceable calibration with certificate; bump-test with SO2 calibration gas and recalibrate on schedule.

How is it powered?

USB-rechargeable, sized for shift-long use including pump operation.

What alarms does it have?

Audible, visual and vibration alarms trigger when SO2 exceeds the set point.

Can it detect other gases?

No — SO2 only. For chlorine use the Chlorine Analyzer; for ammonia the Ammonia Detector.

What are the SO2 exposure limits?

Set alarms to the applicable OSHA PEL and ACGIH TLV/STEL for sulfur dioxide; confirm current values for your program.

Is it in stock and how does it ship?

Use the Amazon buy button for current availability and delivery timing through our fulfillment partner.

Does the sensor need replacing?

Yes — electrochemical SO2 sensors are consumables; replace per the manufacturer's schedule and verify against a known source.

Can I use it for confined-space entry?

SO2 is one hazard; entry also needs O2, combustible and toxic testing. Use a Portable Gas Detectors 4-gas instrument for pre-entry plus this for the SO2 component.
