Corvus Indoor Air Quality Monitor

Ion Science is a leading manufacturer of technologically advanced gas detectors, PID/VOC detectors, SF6 leak detectors, mercury analysers and corrosion monitors, distributed worldwide.

Corvus Indoor Air Quality Monitor

Corvus is a continuous, wireless VOC monitor for Indoor Air Quality (IAQ) containing sensors for temperature, barometric pressure and humidity. Corvus utilises high sense technology detecting Volatile Organic Compounds (VOCs) down to low parts-per-billion (ppb) levels. Its wireless capabilities allow a network of up to twenty instruments to be deployed around the building, with data downloaded and managed via just the one instrument.

The Corvus IAQ monitor continuously detects and data logs a wide variety of VOCs including Benzene, Tetrachloroethylene and Styrene, protecting workers from hazardous gases. The instrument gathers high quality, real trend data for detailed analysis giving a true picture of what is happening within the environment.

The instrument's intelligent interactive mapping software shows real trend data captured within each room. The collection of long-term information eliminates the need for frequent site visits and spot checks, saving both time and money.

Small, sleek and compact in design, the Corvus IAQ monitor allows multiple deployment around the building via wireless connectivity, whilst using minimal space and blending well into the workspace environment.

The Corvus IAQ monitor incorporates Ion Science PID sensor technology, independently verified as best performing on the market for speed, accuracty and humidity resistant operation. Its unique Anti-contamination and patented Fence Electrode Technology provide extended run time in the most challenging environments, giving you accurate and reliable results.

Typical gases include the Corvus detects include Benzene, Ethyl benzene, Styrene, Tetrachloroethylene, Trimethlybenzene, Toluene and Xylene.
