Features: This digital level measures slope angles 4 x 90 (total 360) range. The strong magnets to firmly attach on metal surfaces. The large and clear LCD with backlight for day or night visibility. You can place the meter on a reference surface zero to measure relative angle, then it will give a result of measured slope angle. With absolute angle measurement, you can test whether the working surface is on the level. Great tool for automotive, wood & mechanical industries-, machinery, medical- fields and etc. Specifications: Material: ABS Item size: approx 130x57x36MM/5x2x1in Package size: approx 145x64x44MM/6x2.5x2in Measuring range: 4x90 2x180 Display resolution: 0.050.05 (less than 100), 0.1 (100~180) Accuracy: + / - 0.2 Repeatability: 0.1 Power supply: 2XAAA( Not included) Operating temperature: 0C~40C Note: Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.
