Clearing the Air Around Odor Testing
After several rounds of chemical testing for holding tanks, we have got this stink detection down to a science.
Because the masking chemicals are more effective in in port-a-potty applications, there is only one true measure of effectiveness: whether the toilet still stinks after it is “flushed.“
Since calibrating noses presents certain challenges, it’s nice to have an analytical number to compare as well. A hydrogen sulfide monitor, of the type used to test sewer gas, was used to back-up our sniff testing
We measured hydrogen sulfide (H2S) levels in the holding chamber, using a Honeywell Gas Alert Quattro meter.
1. The door to the “lab,” a pre-fabricated shed, bears a chilling warning
2. As we did in our holding tank test, we used five-gallon buckets in place of the port-a-potty waste tank. They were only partially filled for the test.
3. The Reliance “Double Duty” bags works with its own camp-style toilets, but don’t fit well with marine port-a-potties.
4. The Toilet in a Bag proved to be highly odor resistant and strong. The bags cost a dollar each and the package comes with odor absorbing gel and a scoop for adding the gel.
