Year Founded:

PPM Technology is based in Caernarfon, Wales, UK, where we have a custom built development and production facility on the Cibyn Industrial Estate.

We have developed a range of toxic gas instrumentation based on a unique electro-chemical sensor, which we manufacture ourselves, for the detection of airborne Formaldehyde and Glutaraldehyde. We also manufacture instruments for monitoring multiple common gases, these multi-parameter instruments creates an accurate profile of a building's indoor air quality (IAQ)

We are able to tailor our instruments to meet your particular requirements or situations.

Meet The Team

PPM Technology is split into three inter-linked parts: Administration, Production and R&D. The in-house expertise provided by our nine full time staff is also supplemented by a host of sub-contractors. Consultants are also used if a particular project requires specific expert knowledge.

Supported by a network of experienced distributors, PPM's products are exported to over thirty countries in five continents, with a wide range of industries and health care establishments worldwide relying on PPM gas detection instruments for continued protection against airborne hazards in the workplace.

PPM is committed to providing unparalleled levels of customer service and support and aims to remain a leading company in the field of gas detection in safety & health and indoor air quality applications.

Company History

The name PPM has been associated for many years with toxic gas detection technology ever since PPM Ltd was established by Dr Tom Parry Jones OBE in 1993. Previously, Dr. Jones was the founding owner of Lion Laboratories , a world leader in breath alcohol detection technology, which was sold in 1991 to MPD Inc. of Owensboro, KY.

 In 1999 - when Dr. Jones decided to step down - the company was bought by three employees and re-named to become PPM Technology Ltd. Since the management buy-out the success has continued with increased sales, expanded product ranges and almost quadrupling the number of staff employed. This expansion has necessitated relocation to new premises on the Cibyn Industrial Estate in Caernarfon. 

Why do we need to Monitor IAQ?

Indoor air quality (IAQ) relates to a number of environmental factors inside a building that can impinge on the health, comfort or work performance of the building’s occupants. Monitoring IAQ is vital because it is estimated that the average person spends 90% of their time breathing “indoor air”.  
Poor IAQ is a contributing factor to both short and long-term health issues, these can lead to decreased productivity, absenteeism, and in some cases possible litigation. Common symptoms associated with poor indoor air quality can include eye, nose, and throat irritation, headache, nausea, dizziness, and fatigue. In some cases exposure to indoor air pollution can lead to acute and chronic respiratory illnesses. 

Factors that can contribute to a unhealthy Indoor Air Environment.

Gas and particulates in the air are the principal sources that contribute to unhealthy IAQ. Common factors that can lead to a harmful indoor environment can include inadequate ventilation, poorly maintained HVAC systems, non-vented gas heaters, airborne pollutants carpet fibers, fungal spores, vehicle exhaust emissions, building materials, carpeting, furniture, chemical pollutants (light industrial chemical substances, cleaning substances), Ozone emissions from printers and photocopiers etc. Another problem is recent energy conservation measures that have led to airtight building construction that can create problems with IAQ. The concentrations of pollutants can also be amplified by factors such as poor ventilation, humidity, and temperature.

 IAQ Profile

Indoor Air Quality (IAQ) is an important part of building management as it has an impact on health, safety and productivity of the people who use the buildings in question. An IAQ Profile is a visual presentation of indoor air quality. A good IAQ Profile describes precisely changes in the concentration levels of selected air quality parameters in an indoor environment over a period of time.

Using an IAQ Profile allows building managers to provide a more comfortable working environment by 'predicting' normal situations. The air conditioning system could be tied-in with the profile so that it's not used when CO 2 levels are low and fresh air is not required in the room.

By measuring many different parameters (Temperature, Humidity, CO 2 , CO, Formaldehyde or NO 2 ) the IAQ Profile is an important tool in preventing 'Sick' Building Syndrome and as such is a legal requirement for public buildings in many countries.

Sick Building Syndrome is concerned with a range of symptoms that can effect a worker in particular building. SBS typically occurs in large open-plan offices with automated heating, ventilation and air conditioning systems. SBS can effect people in a particular part of building or even the entire building itself.
