This product is widely used in many places, such as city land, road, airport, mine, electricity factory, etc. It can be used to observe the second, third grade level sedimentation and survey the diastrophism.

This product can be divided the series matched with optical level apparatus (the basis, assistant graduation modes) and the series matched with the electronic water levels (the bar code mode).

A variety of grades, lengths and bodies of modification observation indium leveling staffs are available to the customer＇s demand, all of which can be used with all kinds of water levels at home and abroad.

The principal technical specifications

The series matched with optical level apparatus

With CH800―92 standard invar belt, the coefficient of linear expansion ≤1.3×10-6/℃；the difference between real length and nominal length per meter ≤±0.08mm；the difference between basic constant and assistant constant and the null point difference of the staff ≤±0.08mm；the angle between the vertical axis and the bottom plane ≤6＇； the degree of curve of the staff ≤4mm；The staff has dual measuring scales, one is in 10mm decimeter increments and the other in 5mm centimeter increments, having two images, one is erect image, the other is inverted image.

The series matched with electronic water levels

As the present international standards, the series can be matched with

The using methods

1.    The staff can be made to stand in the ground and be hung, too.

2.    When the staff stands in the ground, open the red end cap, take the bubble out, nip the bubble in the board of the staff, and make the staff stand in the surveyed point and make the bubble in the center, then we can take on the survey performance.

3.    When the staff is hung, we open the red end cap, take the staff body out, unpack the board of the water level, install the hook (the hook is in the red end cap), hang the location ring the hook on the surveyed point, then we can take on the survey performance.          （△H=H2－H1）
