What does the MS1700 measure?
It measures the concentration of VOC in water measured against a target gas standard (usually toluene). Other compounds can be also targeted.
How often does the instrument provide a reading?
The instrument provides a reading via the 4-20 mA output continuously.
What is the reported value?
The reported value is Total VOCs in the effluent water, in ppm, is in the range from 1 ppm to 100 ppm.
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 analog output.
How is the analyzer 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 ensure there are no air leaks.
What is the warranty?
Every instrument comes with 1 year warranty from the shipment date.
How does the analyzer alert the user to high concentrations of gas?
It incorporates a relay which is switched at a user definable threshold. This can be hardwired to valves/pumps to stop processes very quickly. Alternatively the users SCADA system can also be used.
