Gas Detection 73 Portable and Fixed Gas Detector Range Enhanced
PPM Technology (UK) is pleased to announce a number of significant enhancements to their range of portable and fixed gas detection instruments. Their new Wireless IAQ Profile PPMonitor is able to continuously monitor any Indoor Air Environment. The wireless technology enables real-time monitoring of almost any IAQ parameter including Temperature, Humidity and a wide range of toxic gases and compounds.
PPM Technology’s handheld Formaldehyde detectors the Formaldemeter™ htV and htV-m now offer improved performance and reliability; the instruments are able to accurately measure when extremely high concentrations of formaldehyde are present; this advance is due to innovation in technology; a new valve to regulate the supply of air into the instruments fuel cell.
The sampling mechanisms within our hand-held instruments previously were not suitable for continuous measurements of high concentrations of formaldehyde. We developed the new modified version of the instrument to enable the user to change the settings and monitor for much higher concentrations of Formaldehyde up to approximately 90ppm. This has been achieved through the introduction of a miniature solenoid valve, which ensures a closed system; this prevents formaldehyde from seeping into the sensor when sampling is not taking place. The valve has been designed inertly to measure Formaldehyde.
When the sample button is pressed the valve will open and will remain open for the same duration as the sampling period of the pump. The sample is collected through a length of tube. Previously only a finite amount could be sampled but now it is possible to have the pump run until the tube is filled with the same concentration as the area to be monitored and then take the sample directly from the tube.
The Formaldemeter htv and htv-m can also be wirelessly connected to third party systems via
the PPM Technology interface board (ifB). The interface board can be configured to give different voltage outputs; a 4–20mA current output and also gives a relay alarm output.

Materials Testing Made Easy - From Landfill sites to Pond Liners
Testing the material for a landfill liner has traditionally been a long, complex and expensive task. Not only does it need to be a barrier against water and water vapour, but also it needs to act
against methane, CO2 and a host of other gases and petrochemicals. Unfortunately all of these gasses react differently to each material or Geomembrane, and a product that is highly effective against some of them may virtually useless against another. For example PVC is around 25 times worse as a barrier to Carbon Dioxide than it is for Nitrogen.
Now Versaperm (UK) has introduced a new version of its highly sensitive permeability measurement system instrument that can measure this characteristic of a material for almost any common gas. In some circumstances it can even measure these all at the same time.
Versaperm’s new equipment is fast, sometimes taking just 30 minutes to give accurate and repeatable results. The equipment is highly sensitive, simple to use and provides automated computerised control. It is accurate in the PPM range for most gasses and in the PPB for some. The system is unusual as it can measure anything from thin films to composite structures and even sealed joints.
