a1-cbiss are the UK distributor for Cairpol – A collective group of industrial gas monitoring and mapping products CairTub, CairClip, CairNet, CairMap.

With sensitivity levels down to ppb (parts per billion) which is better than current gas sensors on the market and providing real-time measurement data at a fraction of the cost of reference method analysers, Cairpol systems can be deployed quickly for fixed and portable gas measurement applications.

The highly innovative technology employed and patented by Cairpol provides real-time, cost effective and a practical approach for the wastewater industry in applications such as industrial olfactory pollution / odour monitoring and personal exposure monitoring.


The CairTub allows the easy deployment of autonomous measurement points virtually anywhere. The system can be used in harsh weather conditions. It is also the ideal tool for low cost studies for the optimisation and setting-up of fixed air quality monitoring stations.

With an autonomy of 21 days, these measurement systems consist of a stainless weather protection case for exterior use even in bad weather conditions and the micro-sensor CairSens, adapted to the low concentration measurement of pollutants to be measured (O3/NO2, H2S and Sulphur compounds, NH3 ) or other compounds of specific interest.

Initially designed for oxidising (O3 / NO2) monitoring to warn asthmatics of real-time pollution levels, Cairpol sensor range has been developed further to cover industrial applications including the measurement of sulphur compounds and H2S (typical olfactive nuisances from waste water treatment facilities) and ammonia (characteristic odour from decomposition processes).


CairNet is a simple and efficient way to monitor processes and plant surroundings via a wireless communicating network and autonomous (solar panel and battery). CairNet surveys fugitive emissions of toxic gases or odorous gases around waste water treatment plants (WWTP), allowing you to react quickly to gas leaks.

The CairNet allows the wireless survey of hundreds of measurement points within a 200m radius of the wireless receiver for a much efficient installation cost.

Every CairNet measurement point consists of:

  • Weather protection cases in stainless steel, equipped with a miniature sensor
  • Solar panel and its battery
  • Radio communication module

Associated with the application software CairMap, it is possible to show real-time fugitive emissions of a multi-source installation for the management of events and processes. All sensor readings available on a 24 hour / 30 day scale is displayed and represented by a colour scale level of concentration.

Cairpol systems can be also used to supplement conventional air quality stations by offering additional measurement points providing additional coverage and measurement data for an area, the data and software is compatible with Air Quality Data Acquisition systems.
