PPM IAQ Multiparameter Profile Monitor

PPM Technology (UK) have dedicated over 10 years to the monitoring of airborne gases and are pleased to announce the launch of theirmost innovative and adaptable monitoring system, the PPMIAQ ProfileMonitor. The systemis designed to operate in a fully self-contained manner; with an inbuilt computer using Windows® based software. Being compact, and lightweight, the IAQ Profile Monitor can easily be moved to different locations, buildings and environments. Continuous or daily scheduling of sampling is possible allowing total automation for the duration of the sampling period. The system can also be networked for retrieval of data whilst sampling or to change any of the stored settings from a remote location. It is possible to network more than one IAQ Monitor at a time.
PPM’s exclusive designed Windows® based software provides the user with a real time, visual representation of indoor air quality. The user can easily pinpoint the exact time changes in air quality occur, since the IAQ Profile Monitor logs data every 60 seconds. It works out the data value by a running average over the whole minute, not just from a single data point every 60 seconds. The user can easily pinpoint the exact time changes in air quality occur. Unlimited storage of data and the ability to create place and session specific reports can also assist building management systems and help fulfil legislative requirements.
The PPM IAQ Profile Monitor has been developed to ensure that monitoring is thorough, accurate, applicable and cost effective, and to allow flexibility and freedom in monitoring IAQ levels. Offering extreme versatility the portable IAQ monitor simultaneously measures up to 8 IAQ parameters that have been specifically chosen by the systems user. Sensors have been chosen to offer the highest levels in precision and quality ensuring complete accuracy of readings, and safeguarding the health of building occupants. Sensor range options include but are not limited to, formaldehyde, temperature, humidity, carbon dioxide, carbon monoxide, sulphur dioxide, nitrogen dioxide, ozone, and TVOC.
The PPM IAQ Profile Monitor incorporates many advanced sensor technologies. These include the highly accurate Nondispersive Infrared (NDIR) sensor for carbon dioxide detection, Photoionisation Detectors (PID’s) for sampling of total volatile organic compounds, advanced CMOSens technology for temperature and relative humidity and electrochemical sensors for detection of the other various target gases.
The sensors within the IAQ Monitor sample the air mainly by Augmented Diffusion. This means that air flow over the sensors is not forced by a pump. There are 3 fans situated at the back of the instrument, these fans remove heat created by the processor of the instrument and also act to pull air through the monitor creating increased airflow over the sensors.
The augmented diffusion method is preferred by PPM for many good reasons. Firstly, it gives a more accurate representation of the surrounding air quality since the pollutant is allowed sufficient time to diffuse evenly into the air. If a pump were used, this would speed things up, maybe exaggerating the conditions, causing errors, which in turn give misleading results.
Another advantage of using diffusion is that it helps prolong the lifetime of the electrochemical sensors used in the instrument. These kinds of sensors depend upon an aqueous electrolyte in order to work efficiently. By forcing air over such sensors, the gas stream could remove the electrolyte and cause them to dry out thus reducing the lifetime of the sensors.
The system provides a dual environmental benefit; real-time functions enable immediate warnings of the presence of harmful gases, protecting employees and the public.
Analysis of recorded data also allows more efficient management of resources and energy.
