The Forensics Sulfur Dioxide Analyzer is a handheld, NIST-calibrated SO2 gas detector reading 0-20 ppm with a built-in pump and 4 ft probe for refineries, pulp and paper, and food processing, letting you survey and sample SO2 remotely — a monitoring device, not respiratory protection.

Why the Forensics Sulfur Dioxide Analyzer surveys SO2 with a pump and probe
Sulfur dioxide is toxic and pungent, and it shows up around refineries, pulp mills, and food-processing fumigation — places where you often need to check a remote or elevated point. This analyzer handles that: a handheld SO2 detector reading 0-20 ppm with a built-in pump and a 4 ft probe to sample from a distance, with audible, visual and vibration alarms and NIST-traceable calibration. It covers a gas the four-gas set does not read. As sulfur dioxide detectors go, this is the portable pump-survey pick, and the gas detection guide and the diffusion vs pump guide explain where it fits. It samples SO2 from a safe distance.
Safety first: a gas detector alarms; it does not protect. In an IDLH or oxygen-deficient atmosphere you must evacuate and use supplied-air or an SCBA — a monitor warns of the hazard, it is not a substitute for respiratory protection. Bump-test and verify the sensor on schedule, confirm the range and alarm setpoints on the listing, and match the setpoints to your action levels.
What the Forensics Sulfur Dioxide Analyzer listing documents
From the published specs: a handheld NIST-calibrated SO2 detector; a 0-20 ppm range; a built-in pump and 4 ft probe for remote sampling; audible, visual and vibration alarms; and a USB-rechargeable body. These are true portable SO2 detector and sulfur dioxide pump analyzer credentials in an SO2 survey monitor. Confirm the range and alarm setpoints on the listing.
How the Forensics Sulfur Dioxide Analyzer compares to other gas detectors
For a portable chlorine analyzer, the Forensics Chlorine Analyzer; for a portable hydrogen analyzer, the Forensics Hydrogen Analyzer; for a handheld ammonia monitor, the Forensics Ammonia Detector; for a handheld VOC monitor, the Forensics VOC Detector; and for a portable four-gas with pump, the Forensics 4-Gas with Pump. The 4-gas vs single-gas guide explains when a dedicated single-gas monitor is needed.
Choosing the right gas monitor
Match the gas, sampling method, and range to your hazard. Browse the gas detectors, personal gas detectors, and portable gas detectors collections; for area and fixed coverage, the area gas monitors and fixed gas detection systems collections; and for calibration, the calibration accessories and gas leak detectors collections and the personal monitor guide.
Where it fits by job and crew orders
The Forensics SO2 Analyzer suits refineries, pulp-and-paper mills, food-processing plants, and combustion facilities that need to survey for sulfur dioxide or sample a remote point — see the gas detection guide and the gas leak detector guide for adjacent tools. A portable pump analyzer lets an industrial hygienist chase a source rather than wait for a fixed monitor to alarm. Confirm the range and alarm setpoints on the listing, verify the sensor on schedule, and replace it at its service interval.

What a gas monitor has to satisfy
Gas detection instruments carry hazardous-location approvals where the atmosphere may be flammable — Class I Division 1 or 2 in the US, or an ATEX/IECEx equivalent. Those approvals apply to the instrument as configured: swapping a sensor or battery pack outside the listed combination voids them.
The number that governs use is the exposure limit, not the display. 29 CFR 1910.1000 sets permissible exposure limits, and NIOSH publishes RELs and immediately-dangerous concentrations that are frequently lower. For confined-space entry, 1910.146 requires testing in a fixed order — oxygen first, then flammables, then toxics — because a reading taken out of order can be actively misleading.
Every electrochemical sensor drifts. Bump test before each day of use and calibrate on the manufacturer schedule with a known concentration. An instrument that has not been bump-tested is an indicator, not a monitor.

Frequently asked questions
What is the Forensics Sulfur Dioxide Analyzer?
A handheld, NIST-calibrated SO2 gas detector reading 0-20 ppm with a built-in pump and 4 ft probe for refineries, pulp and paper, and food processing, letting you survey and sample SO2 remotely.
What does it detect?
Sulfur dioxide (SO2) only, from 0-20 ppm - a toxic gas that the standard four-gas set does not measure. Confirm the range and sensor on the listing.
What does the pump and probe do?
The built-in pump and 4 ft probe draw a sample from a distance, so you can survey for an SO2 source or sample a remote or elevated point without standing in the gas. Confirm the probe length on the listing.
Where is SO2 a hazard?
Refineries, pulp-and-paper mills, food processing (as a preservative and fumigant), and combustion of sulfur-containing fuels. The listing positions it for those uses; confirm your exposure sources.
Is a gas monitor the same as a respirator?
No - a gas monitor warns of a hazardous atmosphere; it does not filter or supply air. In dangerous atmospheres you must evacuate and use the correct respiratory protection. Confirm your program's requirements.
Does it ship calibrated?
The listing states USA NIST-traceable calibration with a certificate. Confirm the certificate and the calibration schedule on the listing.
What alarms does it have?
The listing states audible, visual and vibration alarms. Confirm the alarm setpoints on the listing and that they match your action levels.
How is it powered?
The listing states it is USB-rechargeable for shift-long use. Confirm the run time and charging on the listing.
Why not just use a four-gas monitor?
A four-gas monitor covers O2, LEL, CO and H2S but not sulfur dioxide. Where SO2 is the hazard, you need a dedicated SO2 analyzer in addition to any four-gas unit.
How is it carried?
As a compact handheld for surveys and spot checks; confirm the operating and storage conditions on the listing.
How do I care for it?
Bump-test and verify the sensor on schedule, keep the pump inlet and probe clear, charge as needed, and replace the sensor at its service interval per the manual.
How do I order for a crew?
Quantity purchasing runs through a free Amazon Business account - volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations. The bulk-ordering walkthrough is linked in our site footer.
