Measurements of each angles can be made by setting angles of 0-90 °from side to side.This level can be used to draw a line as a ruler.A measurement of the vertical can be made from the front.● Measurements of 1/100 and 2/100 of a gradient can be made.● Easy to read with a magnifying lens● The light absorption sheet absorbs the light at a well-lit area and emits the light at a dark area for several minutes.● Precision is adjustable.● Curing treatment of aluminum alloy extrusion material● Coating of anodized aluminum clear● 6-line acrylic horizontal vial with lens● 6-line acrylic vertical vial● With mirror (except 100mm)● With angle scaleSensitivity 0.35mm/m=0.0201°Precision ±1.00mm/m=within±0.0573°(Angle scale)Sensitivity 0.50mm/m=0.0286°Precision ±34.9mm/m=within±2.0°H51 X W19.5
