Large Brass Dumpy Level (Precision Engineer's Transit) with storage and display box $335
This is a solid brass reproduction of a Dumpy Level, also known as an 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 instrument has an impressive level of quality and craftsmanship.
This dumpy level stands 4 3/4 inches (12.1 cm) tall, 6 inches (15.2 cm) long,
and weighs a very solid 3 pounds 3.6 ounces (1.46 kg).
The Dumpy Level has a 5-power inverting telescope and a focusing adjustment.
The telescope has a removable brass lens cap to protect the large 1.5 inch (38 mm) diameter objective lens.
On the left side of the telescope, there is an adjustable spirit level with a protective cover.
On the inside of the cover is a mirror to assist in reading the spirit level.
There are three leveling adjustments on the base and it is threaded for a surveyor's
tripod mount.
Utilizing the fine tuning control allows for the azimuth angle to be accurately adjusted.
Please note that the Dumpy Level is fully functional, but is not certified accurate for surveying.
A beautiful solid hardwood box is included for storing or displaying the Dumpy Level.
The polished brass Dumpy Level is available for $335.
We also offer a Small Dumpy Level with Hardwood Case.
