Indoor air quality meter (IAQ)
Surveyor GrayWolf Sensing Solutions

With 90% of our time spent indoors, determining the quality of the air we breathe indoors is essential for good health and productivity. The IAQ Surveyor II and IAQ Surveyor Pro monitor key indoor air quality indicators including carbon dioxide, humidity, temperature and carbon monoxide. Should these measurements fall outside internationally recognized guidelines, further tests can be made to suggest an appropriate course of action.

For example, studies into poor ventilation show that as room temperatures rise above 24°C (75°F) the concentration levels of occupants can drop by up to 50% and high levels of carbon dioxide result in drowsiness and perceived stuffiness. Both situations are very common and seriously affect productivity. Over-ventilation wastes energy and results in increased building running costs.

The IAQ Surveyor PRO includes a built-in micro-manometer to measure static pressure and differential pressure. The auto-zeroing pressure sensor allows for pollution pathways, HVAC systems, filter blockages and many other processes to be assessed for optimum performance. A type K thermocouple socket is also included for measurement with a variety of temperature probes: air, immersion, penetration, surface and other specialized temperature probes.

The Surveyor range has been designed with the user in mind. The large rubber grip, pushbuttons and hand strap ensure the units are comfortable to use, even with gloves on, and the side probe fixing allows single-handed operation.
