Indoor Air Quality (IAQ)

The New, Advanced AQ Series are highly accurate, durable, compact and user-friendly IAQ monitors, designed to meet the needs of testing professionals in ANY Air Quality applications (Inspectors, Laboratories, HVAC Warehouse, IAQ, Greenhouse, Offices, Commercial, Residential, and many more).

E Instruments AQ Expert portable indoor air quality monitoring system (IAQ Monitor), manufactured at the E Instruments’ factory in the USA, incorporates the latest and most sophisticated sensor technologies in order to provide precise measurements of the parameters most critical to indoor warehouse air quality.

Some of the more harmful indoor air pollutants such as Volatile Organic Compounds (VOCs) and Carbon Monoxide (CO) that could cause serious short and long-term health effects can be accurately monitored using the AQ Expert VOC Monitor. This AQ Monitor can accommodate up to six (6) electrochemical gas sensors (CO, NO, NO2, SO2, Ozone O3, H2S, O2, Formaldehyde CH2O), one (1) infrared gas sensors (CO2) and one (1) PID sensor (VOCs) in addition to measuring Relative Humidity, Ambient Temperature and Barometric Pressure.

By offering the Indoor Air Quality (IAQ) professionals the ability to customize their IAQ Monitors to specifically meet their own specific requirements anywhere from 1 gas measurement (CO2 only) up to 8 total gas sensors in one IAQ Monitor, E Instruments’ IAQ Monitors separate themselves from the competition. 

The Vaisala GMW80 Series is a wall-mounted CO₂ and temperature transmitter designed to monitor indoor air quality and occupancy levels. By measuring CO₂, it helps ensure adequate ventilation, improve occupant comfort and productivity, and reduce energy consumption by avoiding unnecessary use of outside air.

The GMW80 is designed for HVAC and demand-controlled ventilation applications, making it particularly suitable for buildings that are occupied continuously.

It uses Vaisala’s second-generation CARBOCAP® sensor technology, featuring a microglow light source and an internal reference measurement. This provides long-term stability, reliability, and accurate measurements from start-up, with minimal need for recalibration or maintenance.
