Searching for Monitoring Equipment for VOCs, Ozone and other indoor air pollutants

Hi guys,
Just wondering if anyone can recommend some decent monitoring equipment thats budget-friendly, specifically for VOCs, Ozone (must be able to withstand high humidity), and other indoor air pollutants.
I've been trawling the web for ages most dont give prices and its all very confusing really

thanks for any help

Re: Searching for Monitoring Equipment

Try looking up a magazine called "Environmental Protection" and another called "Pollution Engineering" both are free and both publish an annual suppliers catalog. I'm sorry I don't have the addresses.

There are many instruments for detecting the concentration of VOCS and ozone, but they are separate. Usually, there is no instrument that can detect both VOCS and ozone. This is related to the use environment.

Another problem is the accuracy of the instruments. For example, there are many types of ozone space detectors, but there are only a few very accurate in the world, such as P&C in Italy and Prominent in Germany.
