Aeroqual 300 Series Portable Gas Monitor

Take control of air quality with the Aeroqual 300 Series, a compact handheld monitor designed for fast, reliable gas measurements wherever you work. Its interchangeable sensor heads let you measure exactly what you need today and adapt for tomorrow, covering up to 30 pollutant types including ozone, NO₂, SO₂, CO, VOCs and more. A bright LCD shows real‑time concentrations at a glance, while high and low alarms and a practical control mode help you react instantly to threshold exceedances. With ppm or mg·m⁻³ readout, active fan sampling for stable accuracy, and a long‑life lithium battery, the 300 Series is a proven field partner for leak detection, process control, and indoor air quality checks. Available now from Stratosens.com.

Key Benefits and Applications

• Measure what matters today and tomorrow — Swap sensor heads in seconds to monitor ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide, hydrogen sulfide, ammonia, VOCs and more, matching each task without buying a new instrument.
• Real‑time decisions with clear visuals — Large display shows live readings plus minimum, maximum, and average values so teams can verify trends and act confidently during inspections.
• Control mode for process safety — Use the analog output to trigger external equipment when gas levels cross your set limits, ideal for ozone generation control and containment workflows.
• Accurate results in the field — Active fan sampling pulls air across the sensor for stable, repeatable measurements that outperform passive diffusion approaches in changing environments.
• Quick zero and span on site — In‑field calibration keeps the monitor on the job, minimizing downtime and ensuring defensible data for compliance and audits.
• Portable and versatile — Lightweight design fits one hand for walk‑through surveys, and with an optional wall bracket and mains power it can function as a simple fixed monitor between rounds.
• Trusted for IAQ and HSE tasks — Ideal for indoor air quality surveys, leak hunting, personal exposure checks, commissioning, and health and safety verification across labs, manufacturing, and facilities.

Featured technical specifications

• Interchangeable sensors — Swappable sensor heads cover up to 30 pollutants, including multiple ozone ranges that extend to 30 ppm, plus optional temperature and relative humidity.
• Measurement display — Gas concentrations shown in ppm or mg·m⁻³ with instantaneous, minimum, maximum, and average readouts on a large LCD.
• Sampling method — Active fan sampling to support high‑quality measurements and rapid response in real environments.
• Alarms and indicators — User‑set high and low alarms with audible alert and on‑screen status indicators for battery, sensor, and standby.
• Analog output and control — 0 to 5 V output enables simple integration with external devices and supports control mode for threshold‑based actuation.
• Calibration — Zero and span calibration performed in the field to maintain accuracy without returning the base unit.
• Operating conditions — Designed for -5 to 45 °C and 0 to 95 percent relative humidity non‑condensing to suit typical indoor environments.
• Optional T and RH sensor — Temperature measurement from -40 to 124 °C and relative humidity from 0 to 100 percent when the combined sensor head is fitted.
• Power and battery — Rechargeable lithium‑ion battery rated at 12 V and 2700 mA·h with universal charger 100 to 250 V AC for global use.
• Dimensions and weight — Compact footprint of 195 × 122 × 54 mm with sensor head and a mass under 460 g for easy one‑hand operation.
• Enclosure and rating — Durable PC and ABS housing with IP20 protection for indoor applications.
• Compliance — Meets Part 15 of FCC Rules and EN 50082‑1 and EN 50081‑1 for electromagnetic compatibility.
• Data handling — On‑board data logging is not included on the 300 Series. Use the analog output for external logging or choose a model with integrated logging if required.
