Q: How do i know when the co2 tank is low? the included regulator has no gauge.

In relation to the CO2 tank levels, the problem is that the CO2 in the cylinder is compressed into a liquid with only the vapour pressure being measured by a gas pressure gauge. The gas pressure in the cylinder remains pretty much the same even when there is only a small amount of liquid CO2 left in the cylinder. In other words, the gas pressure does not fall linearly with the liquid CO2 level. As the remaining vapor is fully consumed, the pressure shown on the gauge will drop off very rapidly. This means that the cylinder gauge may read 900 psi until almost all the liquid CO2 has gone. That confuses a lot of people who check the gauge one day only to find that the next day the cylinder is empty.This is why we tell customers not to bother buying a gas pressure gauge for their CO2 cylinders. Actually, the best way to monitor the contents of the cylinder is by weight. Weigh the cylinder full then subtract the cylinder's tare (empty) weight, which is usually shown on the outside of the cylinder. The difference between the two is the weight of liquid CO2 in the cylinder. Thus when this difference has reduced by 50% then 50% of the CO2 has been used.

Q: How big of an area does this reach? I see some are 1/2 to 1 acre. Needing to find the best for the biggest area.

Thank you for your question. The ULTRA mosquito trap has a maximum coverage area of 1.5 acres (0.6 hectare). This trap covers the largest area and is the most effective against a large range of mosquitos. Hope this helps.

Q: Is this the model mcu-900 or the next generation mcu-910 ?

Yes, it is the 910 Model. The 910 is the newest version of the Pro 900 Range.

Q: Does it work in a small backyard less than 1/100 acre?

I imagine it will work fabulous as you will do your property and all your neighbors property as well. I have a little more than a quarter acre and as long as I clean the machine regularly it does a great job.
