Of course. Great Phosgene producer. H-10 is the only way to go. Bought my first one in 1966. Has not changed much. Sometimes a little oversensitive. But it is the oldest one on the market that I know of. The worst one I ever had was a tiff. I have had most of them. The ultra sonic has its place. But when all else fails the H-10 will get er done.
If you really know how it works, you have an execellent chance of fixin' er up!
