Best value
For the money, the HH311 cant' be beat. They are reliable, repeatable, and accurate.
We have several in our shop and will continue to use them!

Well designed and packaged
I purchased this last week and am very satisfied that I did.
Works well. Easy to use. It appears that the reading is accurate.
The unit came with a RS232 connector for data logging. Software included.
