Carbon Monoxide testing
We have recently purchased a new Carbon monoxide tester. We can test CO in ppm up to 10,000 ppm and above that in percent. We are testing every new unit prior to delivery and to say the least, it is very interesting. First, no two motors have tested alike. The 13 hp motors will test from 14,000 ppm to 21,000 ppm. The 6.5 hp motors have very little test history yet, but it would seem they will test in the 15,000 ppm range. The twin V 20 hp motors are testing from 30,000 to 40,000 ppm. We have tried and will continue to test methods to increase the CO levels. Soaking the foam air filter cover in oil and wringing out the excess oil seems to not effect the motors running and does increase the CO by about 1,000 ppm. Choking the motor by about 1/8″ to 1/4″ has had a dramatic effect on the CO, from 20 to 40 percent increase. This does not seem to effect the power of the motor.
I have advised those that call in with poor kill rates to concentrate their treatment area at any one setting to a local area of 20′ or less. Do not spread out the wands because that will only reduce the toxicity level in all the burrows. Remember, we are building up the toxicity level by probing a single burrow system multiple times. A single probe in a separate burrow system will not kill the gopher but will take CO away from the other probes.
As we ger more information on our testing of the CO levels, I will post it here.
