Improved Sensor Capabilities Advance Air Quality Monitors
Particles Plus says its latest environmental sensors improve performance and accuracy of the company’s line of air quality monitors.
The enhanced sensor for CO2 employs a non-dispersive infrared (NDIR) detector that, coupled with free enhanced field calibration software, provides tighter accuracies and field adjustable offsets, the company says. The NDIR sensor has a range of 0 – 5000 ppm with a 1 ppm resolution and ±1 percent accuracy.
Additionally, the new miniature photo-ionization detector’s (PID) design allows for performance over a range of 0 – 20 PPM, with a resolution of 1 part per billion and an accuracy of ±1.5 percent. The company says the stability and performance is ideal for measuring harmful volatile organic compounds.
Particles Plus says field application testing and customer feedback led to the air quality monitors’ upgrades. The products are a “necessary tool” for manufacturing process control, indoor air quality control and contamination exposure monitoring, and occupational health and industrial hygiene studies, says David Pariseau, the company’s chief technical officer.
