Description

About the manufacturer

MRU is a German company making extremely well-engineered emission monitoring systems. Their products are very durable and constructed to withstand everyday use in punishing environments

 

Product Overview

The SWG 300-1 is a multi-component extractive cold-dry gas analyzer. The NDIR modules measure continuously, selectively and highly accurately within the ppm range. NO2 is catalytically converted into NO for true NOx measurements.  

 

Features

  • Standardized 19″ racks are mounted in a steel metal enclosure with fixing eylets for wall mounting.
  • Complete gas conditioning using electrical gas cooler with automatic condensate draining pump, with high-grade sample gas filtration for separation of water, tar and dirt.
  • Sample flow monitoring and alarm, with auto-zero and auto-span calibration.
  • RS 485 for data communication and 8 channel, user free configurable analog outputs 4 … 20 mA, self powered
  • Air conditioned weather proof enclosure (for outdoor mounting)

Product FAQs

I have an Optima-7 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.
