SULFUR DIOXIDE (SO₂) DETECTOR RENTALS
Ensure safe sulfur dioxide (SO₂) exposure levels with dependable detector rentals from RAECO Rents. Sulfur dioxide (SO₂) is a colorless gas with a sharp, pungent odor commonly produced during combustion processes, fuel refining, metal smelting, power generation, and pulp and paper manufacturing. Exposure to elevated SO₂ levels causes respiratory irritation, difficulty breathing, and eye irritation. At high concentrations, sulfur dioxide can trigger severe bronchospasm and pulmonary edema, particularly in individuals with asthma or other respiratory conditions. Our SO₂ monitors support compliance with OSHA, EPA and NIOSH exposure guidelines.
RAECO Rents offers multi-gas monitors with SO₂ sensors and combustion analyzers capable of measuring sulfur dioxide alongside other emissions gases. Our rental fleet includes the Testo 350 Engine Kit for emissions testing and MultiRAE series monitors for industrial hygiene applications. All equipment ships calibrated and ready to use.
FREQUENTLY ASKED QUESTIONS ABOUT SO₂ DETECTORS & MONITORS
What is the difference between the ToxiRAE Pro SO₂ and the Testo 350?
The ToxiRAE Pro SO₂ ($95/day) is a compact personal monitor designed for worker safety, measuring SO₂ concentrations in the ppm range with real-time alarms. The Testo 350 ($275-325/day) is a professional combustion analyzer that measures SO₂ alongside O₂, CO, NO, NO₂, and hydrocarbons for emissions compliance testing on engines, boilers, and turbines.
Where is sulfur dioxide monitoring required?
SO₂ monitoring is essential in power plants, refineries, metal smelting operations, pulp and paper mills, chemical manufacturing, and facilities using sulfur-containing fuels. Emissions testing firms and environmental consultants use SO₂ analyzers for stack testing, EPA compliance, and air quality assessments.
Which SO₂ detector is best for emissions testing?
The Testo 350 Engine Kit ($275/day) or Testo 350 with Hydrocarbon Sensor ($325/day) are ideal for emissions testing applications. These analyzers measure SO₂ up to 5,000 ppm alongside other combustion gases, providing comprehensive data for EPA compliance on engines, boilers, turbines, and industrial combustion systems.
Why is monitoring sulfur dioxide important?
SO₂ exposure can cause respiratory irritation, difficulty breathing, and long-term health effects. Monitoring ensures safe working conditions, supports regulatory compliance, and provides early warning when concentrations approach hazardous levels. Sulfur dioxide has a sharp, irritating odor detectable at concentrations as low as 0.3-1 ppm. However, relying on smell is dangerous because prolonged exposure causes olfactory fatigue, and individual sensitivity varies. Electronic monitors provide the only reliable method for safety and compliance monitoring.
When should SO₂ detectors be used?
SO₂ detectors are ideal for environmental consultants, emissions testing firms, and industrial facilities performing stack testing and regulatory monitoring on engines, boilers, turbines, and industrial combustion systems
How much does it cost to rent an SO₂ detector?
SO₂ detector rentals from RAECO Rents start at $95/day for the ToxiRAE Pro SO₂ personal monitor, $105/day for the MultiRAE Lite and $275-325/day for Testo 350 combustion analyzers.
