BRASS SIEVES (20cm DIAMETER)
Bolhes supplies soil sieves in two types: full depth test sieves and half depth sieves. Brass Metal mesh soil sieves have small size and light weight, allowing for high efficiency & high accuracy lab testing. The depth refers to the distance from the cover of the sieves o top of the sieve frame to the wire mesh fabric it uses for filtering.

SOKKIA AUTOLEVEL (MODEL - B40A)
An auto level is an optical instrument that can be used to establish or verify points on the same horizontal plane, and it has an internal mechanism that eliminates variation and inaccuracy from measurements.
-
TOTAL STATION(S)
A total station (TS) or total station Theodolite (TST) is an electronic/optical instrument used for surveying and building construction. ... This eliminates the need for an assistant staff member as the operator holds the retroreflector and controls the total station from the observed point.
