Aeroqual Sensor Heads

Sensor Heads

Aeroqual sensors are housed with in an interchangeable ‘sensor head‘ that attaches to the monitor base. You can choose from up to 27 different sensor heads. Each sensor contains a single gas or particle sensor. Swapping sensor heads takes seconds and no configuration or re-calibration is required.

Right Tool, Right Job

Aeroqual uses a mix of sensor technologies; each one based on rigorous testing and depending on the target pollutant and application.

GSS (Gas Sensitive Semiconductor)

Our gas sensitive semiconductor (GSS) sensor uses proprietary sensing material, built in automatic baseline correction (ABC) and interference rejection. This combination results in ppb resolution and a highly linear response.
Parameters: Ammonia, Carbon Monoxide, Hydrogen, Methane, Ozone, Perchloroethylene, VOC.

GSE (Gas Sensitive Electrochemical)

Our gas sensitive electrochemical (GSE) sensors generate nano-amp currents proportional to the gas concentration. Aeroqual uses low noise electronics to capture these signals resulting in low detection levels.
Parameters: Ammonia, Carbon Monoxide, Chlorine, Formaldehyde, Hydrogen sulfide, Nitrogen dioxide, Ozone, Sulfur Dioxide.

LPC (Laser Particle Counter)

Our laser particle counter (LPC) for Particulate Matter (PM) measurements uses optimized signal processing using low noise electronics, we add algorithms to correct for interferences, e.g. humidity.
Parameters: Particulate Matter

NDIR (Non-dispersive infrared)

Our non-dispersive infrared (NDIR) sensor uses infra-red light, a narrow band-pass filter and photodiode to measure the intensity of light at the gas absorption band. The light intensity is proportional to the gas concentration.
Parameters: Carbon Dioxide

PID (Photoionization detector)

Our photoionization detector (PID) sensor uses a krypton filled UV lamp to ionize VOC gas molecules and generate a current that is proportional to the VOC concentration. The PID sensor responds to a wide range of VOCs and is
industry recognized.
Parameters: VOC
