Clean Construction&Bug Free Grow Rooms.
Clean construction is a relatively new industry. It has become necessary for hospital, pharmaceutical, and indoor grow room construction and remodel work. This meter is a great toolfor this work. Clean areas must be slightly pressurized, to prevent contaminates from drifting in. This meter is awesome. Extremely sensitive. I can read 0.001 psi, "wg, or mbar(whatever that is) although accuracy is not garenteed at such a slight pressure, it's more than sufficient for any application that I know about. It's small and rugged, built for construction, and runs on a 9v battery. A heavy rubber removable boot, covers and protects from drop damage, and contains a powerful magnet that allows you to secure it anywhere.I will also use this instrument to search for drafts while winterizing homes. point the hose at a door or window edge, and you'll find 'em. :)

Found less expensive locally
After I bought it online, I found it $20 cheaper from a local supply house, Johnstone Supply. My fault I didn't shop more wisely.

Value-priced
Works okay. The design is adequate, but the manual is a little vague. Value priced and clean/neat features. Would recommend.

Manometer
Very good unit. It will be used for monitoring evap leaks on cars. It has the ability to monitor both sides of the Evap system at the same time showing you any decay in pressure. With Min Max you don't even have to sit and watch it.

Ask the man of the house.
This must be a great product as my husband has not complained of it being otherwise and I know he would complain if there was anything wrong with it.
