What is the principle of operation?
The system samples the air above the effluent/sewage continuously; this air is then passed through the sensor which reacts with VOCs and measures their concentration. The concentration is then reported via the analogue output.
What does the MS1800 VOC Gas Analyzer actually measure?
The MS1800 measures the concentration VOC gas measured against a target gas standard (usually toluene)
How often does the instrument provide a reading?
The instrument provides a reading via the 4-20 mA output continuously. 15, 20, 30, 60 minute interval modes available on request.
What is the reported value?
The reported value is Total VOCs, in ppm, is in the range from 0 to 500 ppm
How is the MS1800 calibrated?
The instrument is factory calibrated against toluene.
What are common target gases?
Petroleum Gas, Methane, Iso Butane, Kerosene, Ethanol, Diesel, Iso-butylene, Toluene, Acetone, Xylene, Heptane, Benzene, Methanol Mercaptan
What is the required maintenance? Is it expensive?
The instrument requires a service every 6 months to replace some low cost components such as activated carbon filters and to make sure that there are no air leaks.
What is the warranty?
Every instrument comes with 1 year warranty from the shipment date
How does the MS1800 alert the user to high concentrations of gas?
The MS1800 incorporates a relay which is switched at a user definable threshold. This can be hardwired to valves/pumps and so on to stop processes very quickly. Alternatively the users SCADA system can also be used.
