DSZ3 Series Automatic Level

DSZ3 series automatic level is a precision surveying instrument both optical and mechanically. With a horizontal scale ,and meets the demand for the application in civil engineering, architectural engineering and land surveys to measure altitude difference, horizontal angel as well as distance by using the stadia lines.


DSZ3-A		DSZ3-B

Features:

DSZ3 comes in a compact,sturdy, and easier to use carrying case. Horizontal line of slight stability is assured by four suspension wires
and magnetic damping compensator. Accuracy over 1km double leveling is ±mm, but for models DSZ3-30A,DSZ3-32A it can be
improved to ±mm combined with the optional parallel plate micrometer.

Excellent structure is sturdy,compact, and more tightly sealed against humidity and dust for superior performance whatever the
conditions. It is quick and easy to set up, simple to sight, and immune to vibration, shock, and other environment conditions.

Four suspension wires and magnetic damping action ensure stability, even under rapidly changing atmospheric conditions, vibration ,
and shock. The reliable automatic compensator is high quality, with a large ±15’

The levels comes with an easy-to-use horizontal circle for measuring angles(direct to 1±or 1gon). The readout window is conveniently
located on the instrument base-directly below the eyepiece.

The level incorporates an endless horizontal motion drive with two knobs for fast and easy aiming, operable with the right or left hand.
simply turn the instrument, then use the fine motion to precisely aim the level at the target.

The stadia wires on the reticle allow easy calculations of distance, Simply the distance on the rod between the top and bottom stadia
lines by 100.

Standard equipment: Instrument, Lens cap, Flannelette, Plumb bob, Vinyl cover, Tool kit, Operation manual, Plastic case
