The building compares a list with electronic level feet and traditional standard feet
Compare index
The building uses electronic level rule
Traditional standard feet
Working principle
Use digital type angle to sensor and personal computer technology are developed and be become
Use level bubble shift, naked eye differentiates, artificial make level, measure computation
Scale division value
0.01 °
5mm/m (0.028 ° ) 10mm/m(0.057 ° )
Measure range
- ° of 5 ° ~ 95
Measure precision
Highest can amount to 0.01 °
Function
Absolutely angle, opposite point of view, rake is measured, data maintains
Can detect only level or perpendicular, cannot measure aleatoric angle and opposite point of view
Feet body material
Oxidation of horniness positive pole treats aluminous capable person, hardness is tall caustic of changeless form, wear-resisting
Material of woodiness, plastic, common aluminium, changeful form
Reading
