Surface Roughness Tester Leeb 410 - Ra:0.05-1 O .Oµm Rz:0.1-50µm

Measure the roughness profile with the Leeb 410 - Ra:0.05-1 O .Oµm Rz:0.1-50µm is a high precision portable Surface Roughness Tester with five optional sensors for measuring special-shaped work-pieces. It uses a DSP chip controlled to achieve high accuracy and fast testing speed. Besides its Matrix LCD screen displays all parameters and data, it complies with ISO/ DIN/ CE/ JIS/ FCC standards. It is powered by a 3.7V rechargeable Li-ion battery. Shell: ABS engineering plastic injection, durable, anti-electromagnetic interference. Readings are indicated in Ra and RZ. Ra is the arithmetic mean average of the total values of the roughness profile ordinates, while RZ is the arithmetic mean of the single roughness depths of successive sampling lengths. Roughness parameter Ra, Rz, Rq, Rt Measuring range Ra:0.05-1 O .Oµm Rz:0.1-50µm Resolution 0 .01µm Cut-off lengths 0 .25mm I 0 .8mm I 2 .5mm Evaluation length 1.25mm I 4mm I 5mm Tracing length 6mm Standard ISO, DIN, ANSI, JIS Error of indication ≤±10 % Variation of indication <3% Sensor Piezocrystal Arc Radius & Angle of Sensor Radius of sensor stylus :10.0±2 .5µm Angle :90 ° Force & Change rate Sensor stylus fore: ,,;; o.016N ; change rate: ,,;; soON/ m Stylus force ≤0 .5N Power supply Rechargeable 3 .7V Lithium-Ion battery Operating temperature 0 °C -40 °C Weight 180g Dimension 105x75x24mm Standard configuration: Main Unit, Calibration block, Power charger, optional Supporting platform, manual, certificate, warranty card
