The human nose is particularly sensitive to Hydrogen Sulphide (H2S); a highly offensive odorous gas, reminiscent of rotten eggs. With an odour threshold between 0.005 ppm and 1.5ppm, relatively low levels of Hydrogen Sulphide can result in complaints if industrial plants generate exposure at these levels. A chemical waste treatment plant in the UK has therefore installed a monitoring and alarm system to generate alerts when H2S concentrations reach levels that might cause concern with staff and the Public.
The SPM flex can also be converted to measure many other odours and gases by simply changing the chemical cassette which takes only minutes to complete. The system can be provided as a portable of fixed installation outdoors or indoors and is compatible with the web logger allowing data to be streamed to your PC, tablet or smartphone in real time.
