The SWG-100 Compact is a cost effective stationary biogas analyzer designed for discontinuous measurement. It has user programmable settings for up to 24 measurements per 24 hours. It is typically used in the harsh industrial environments of combined heat and power (CHP) engine gas monitoring.
Basic Equipment
- Plug & play, pre-calibrated sensors
- Safety in use with gas flow restrictor orifice at gas inlet and ventilation
- Efficient sample gas preparation for fast and reliable measurements
- Sampling from low suction up to high pressure gas
- No dilution of the sample gas, neither use of compressed air is required
- Discontinuous measurement, user settable up to 24 measurements per 24 hours
- Up to 2 sites monitoring (time sharing technique) with only one analyzer
- Data storage and event logging on SD card
- IP 54 cabinet for use in harsh environment
- Ready to run delivery, minimum installation work, low service downtime
- May be installed outside or inside

1. Does it need to be installed outside of the hazardous (C1D2) area?
Yes, the standard configuration does not meet C1D2 classification requirements; however, the SWG100 is capable of being outfitted for C1D2 conditions. The quote would have to be revised to include an additional SS enclosure with a constant purge system that calls for continuous compressed air supply. Please let me know if this is a requirement, and will absolutely update the quote accordingly.
2. Does it need to be installed under a canopy or shaded area?
If you are installing outdoors, yes, it will need to be under a canopy or shaded area.
3. What do they recommend for sample lines? Our standard has been 1/8" or 1/4" 316SS tubing (Silconert coated) with heat trace and insulation for wet gas samples. Do you recommend heat tracing the wet samples to keep above dew point?
The recommended/provided tubing size is as follows (Teflon (PTFE) gas sampling line - 0.16"/0.24" 3.28' (DN4/6mm, 1m length) (MAX 200 meters) @ $12.00/m). SS tubing in the same dimensions is absolutely acceptable and widely used as well. Heat tracing can certainly be helpful, mainly in colder environments where condensate freezing within sample lines is possible/expected. Otherwise the condensate auto-drains that are external to the unit, and when installed as close as possible to the unit will remove 99.9% of moisture before entering the unit. Inside the unit, there is additional condensate removal via a continuous peristaltic pump system.

4. Can you quote a 115VAC power supply?
Absolutely, no problem at all. There is no price change; it is just as simple as leaving a note on the order.
5. Does it require any calibration or carrier gas that we have to provide?
Though it's not a requirement, unless you wish to set-up auto-calibration, we can also provide calibration gas if desired, as it can be helpful to have on hand. Typically, we include one cylinder of a 60%CH4/40%CO2/500ppm H2S mix for units that include an H2S sensor when we quote for the start-up/commissioning or calibration/repair service. But we can quote any mix or cylinder size you may be interested in.

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long.
I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do.
I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
