"Indoor Environmental Quality"

As the years are passing, more and more people are spending most of their time indoors and thus having the environmental conditions in those closed spaces seriously affecting our health.

as the name implies, simply refers to the quality of the air in an office or other building environment. "Sick Building Syndrome" is a term many people use to convey a wide range of symptoms they believe can be attributed to the building itself. Workers typically implicate the workplace environment because their symptoms are alleviated when they leave the office. Indoor environmental contaminants can originate within the building or be drawn in from outdoors. If contaminant concentrations are excessive, IEQ problems can arise, even if the HVAC system is properly designed and well-maintained. Investigators have found IEQ problems caused by ventilation system deficiencies, overcrowding, offgassing from materials in the office and mechanical equipment, tobacco smoke, microbiological contamination, and outside air pollutants. Maintaining a healthy and comfortable indoor environment in any building requires an assessment and thereafter the integration of sensors and controls for permanent monitoring.

Indoor environment problems are preventable and solvable.

Multiparameter model 435 IAQ Monitor can be your valuable tool for indoor environmental quality assessment.

The 435 is the latest generation of multifunction instruments. A compact versatile handheld instrument for the measurement and recording of Indoor Air quality parameters including Carbon Dioxide (CO2), relative humidity and room air temperature are available for evaluating indoor air quality. Additionally, absolute pressure, draught, lux and surface temperature can be determined. Upto 8147 readings can be taken at logging intervals from 1 sec to 1 hour +. To determine volume flow, all the possibilities of flow measurement are available, such as thermal probes, vane probes and Pitot tubes.

Naturally single parameter handheld instruments for ambient temperature, thermal comfort (black ball temperature), relative humidity & dew point, air velocity, carbon dioxide, noise, lux, pressure and many others are also available.
