About the manufacturer
MRU SWG 100 Fixed Biogas Analyzer is a Popular Biogas Analyser that is Extensively Used in all Industries Across the World. Ready to Run Delivery, Minimum Installation Work. 35+ Years Of Experience,ISO 9001, UL & Safety Related Certifications for all Product. Buy It Now!

The SWG 100 is the rugged industrial analyzer to use with:

  • biogas plants
  • cogeneration heat and power engines (CHP)
  • bio methane plants (gas to grid)
  • landfill sites
  • municipal or industrial sewage water treatment sites
  • coal seam gas sites

The instrument's main features are:

  • Industry compatible rugged design
  • Standard system safety included with continuous, monitored fan cabinet ventilation and flow
  • Restrictor orifice gas inlet, with sample gas cut-off in case of alarm
  • Sampling from low suction up to high pressure gas pipe
  • No dilution of sample gas is required; direct and continuous/discontinuous measurement, with pressure and temperature compensation
  • Multiple sampling point monitoring (up to 10 sites monitoring), with one analyzer
  • Ready to run delivery, minimum installation work
  • Designed for easy and expedient maintenance

BASIC ANALYZER CONFIGURATION

  • IP54 aluminum cabinet with anti-corrosive red structural lacquer
  • Continuous, monitored air ventilation through cabinet, with failure alarm on display and on system alarm
  • Relay and sample gas supply cut-off
  • Low cabinet size (H x W x D: 700x600x210 mm) and weight only 25kg, suitable for use in limited space
  • Easy access and service of all main components, including sensors
  • Color, backlit 3.5” TFT display for on-site measurement indication, for instrument status and alarm messages
  • Password protected keyboard operation
  • Continuous or discontinuous measuring mode, user selectable
  • Simple, intuitive software guided menu, with status & alarm on display
  • User settable auto-zero interval using ambient air for sensor purging
  • User settable H2S measurement interval time (if H2Slow is installed)
  • Internal sample gas flow monitoring with display alarm using sample gas pump with flow control, for low and high pressure sampling
  • Large inlet sample gas pressure range from -100mbar to +300mbar
  • Stainless steel gas connectors with 1/8” threads, using 6mm bulkhead compression fittings (user customizable)
  • Flow restrictor orifice at sample gas inlet to decrease combustible gas to max 20%LEL for up to 350mbar gas
  • Inlet pressure in case of inside sample gas leaking
  • Universal 90-240Vac / 47-63Hz / 90W power supply
  • RS485 digital interface (Modbus RTU)

I have a Mru optima 7 biogas analyzer and suddenly the H2S readings are bad or very high. Do I need to replace the sensor?

Not necessarily. When the H2S sensor is exposed to high levels of H2S gas, it is recommended to run the instrument with the gas pump on with ambient air for the same amount of time the sensor was exposed to the high level of H2S. This allows for purging of the instrument before turning the instrument off. Be aware though that continued exposure to levels over 5000ppm H2S will damage the sensor.

Is it safe to expose the H2S sensor in an Optima-7 to H2S gas concentrations just below 5000ppm?

Exposure to H2S levels from 2000-5000ppm with moisture will degrade the sensor more quickly. Using filters inline reduces the moisture content of the gas stream entering the instrument.

A gas reading is much lower than expected. Is the sensor bad?

A common cause for lower than expected gas readings is leakage in the instrument. Perform a leak test by connecting the Condensate Separator Tube to the Pressure Connection 1 Port with tubing.

Perform a leak test as described in the User Manual Optima 7 Biogas. If the leak test fails, check for defective or missing o-rings in the Condensate Separator Tube.

If the user uses the Sampling Probe with sampling lines to take gas readings, place a clean Leak Proof Test Cap on the end of the probe spike. Attach the other end of the sampling line onto the Condensate Separator Tube. Perform the leak test. If the leak test fails, check for defective or missing o-rings in the Condensate Separator Tube and for cracks in the sampling line.

The Optima 7 is not displaying a temperature reading after inserting the thermocouple into the instrument.

Look closely at the prongs of the thermocouple. The prongs might be dirty. Use a sponge soaked in a 1:3 vinegar/water solution and gently wipe the prongs. Wipe dry with a lint-free cloth or allow to air-dry.

The Optima 7 will not power down after pressing the OFF key. How do I turn off the instrument?

Simultaneously, press the ESC key and the power button then release both keys. You will have to update the Date and Time setting in your instrument afterwards.
