Small Dumpy Level
(Precision Engineer's Transit)
with Storage Box $215
This is a smaller solid brass reproduction of a Dumpy Level, which is also known as a Precision Engineer's Transit.
A dumpy level is an optical instrument used in surveying to transfer, measure, or set horizontal levels.
The level instrument is set up on a tripod and then accurately set to a leveled condition using the spirit level and leveling screws.
The operator looks through the eyepiece of the telescope while an assistant holds a tape measure or graduated staff vertical at the point under measurement. The instrument and staff are used to gather and/or transfer elevations.
Measurement generally starts from a benchmark with known height determined by a previous survey, or an arbitrary point with an assumed height.
Azimuth readings are taken using the internal magnetic compass.
The Small Dumpy Level has an inverting telescope with precision crosshairs and two focusing adjustments.
The telescope measures 6 1/8 inches (15.56 cm) long and has a removable
brass lens cap to protect the objective lens.
A fine tuning control functions to adjust the azimuth angle.
On the right side of the Dumpy Level there is a see-through magnetic compass.
An adjustable spirit level with a protective cover stamped "Stanley London" is on the opposite side.
The inside of the cover has a mirror to assist in reading the spirit level.
The base has three leveling adjustments and is threaded for a surveyor's tripod mount.
This model measures 4 3/4 inches (12.1 cm) tall, 3 7/8 inches (9.8 cm) wide, and weighs 3 pounds 3 ounces (1.45 kg).
Please note that the small Dumpy Level is fully functional, but is not certified accurate for surveying.
Accompanying your purchase of the small Dumpy Level is a beautiful brass-inlaid hardwood case for storing or displaying the level.
The box measures 5 1/4 inches (13.5 cm) by 4 inches (10 cm) and is 4 3/8 inches (11 cm) tall.
Such a very beautiful and unique instrument will definitely add distinction to any desk or office.
The polished brass Small Dumpy Level and beautiful storage / display box is available for only $215.
We also offer a Large Dumpy Level.
