Accurate Stability Surface Roughness Tester , Handheld Roughness
Measure Instrument SR210 / SR220 portable surfaces roughness tester is a small
handheld instrument with big LCD, high accuracy and various
parameters. It can be used in the laboratory, inspection area or
wherever on-site surface roughness testing is required. Key features: 320μm wide range high accuracy inductance probe; Four filtering methods of RC, PC-RC, GAUSS and D-P; Compatible with four standards of ISO, DIN, ANSI and JIS; DSP chip is used to control and process data with high speed and
low power consumption; Built-in lithium ion chargeable battery and control circuit; Design of mechanical and electrical integration is adopted to
achieve small bulk, light weight and easy usage; Specifications Model | | SR210 | SR220 | Measuring range | Z Axis (Vertical) | 320μm (Ra=80μm) | X Axis (Horizontal) | 17.5mm | Resolution | Z Axis (Vertical) | 0.01μm/±20μm 0.02μm/±40μm 0.04μm/±80μm 0.08μm/±160μm | Measurement item | Parameters | Ra, Rq, Rz, Rt | Ra, Rq, Rz, Rt, Rp, Rv, RS, RSm, Rz(JIS), Ry(JIS), RSk, R3z, Rmax, Rpc, Rmr, Rku, RΔa, RΔq, Rδc, Ry, Rk, Rpk, Rvk, Mr1, Mr2, A1, A2, V0; | Standards | ISO, ANSI, DIN, JIS | Graphic | | Roughness profile, Material ratio curve, Direct profile | Filter | RC, PC-RC, Gauss, D-P | Sampling length (lr) | 0.25 / 0.8 / 2.5mm | Assessment length (ln) | Ln= lr×n n=1~5 | Probe | principle | Differential inductance | Stylus | Natural Diamond, 90°cone angle, 5μm tip radius | Force | <4mN | Skid | Ruby, Longitudinal radius 40mm | Traversing speed | lr=0.25, Vt=0.15mm/s lr=0.8, Vt=0. 5mm/s lr=2. 5, Vt=1mm/s Return Vt=1mm/s | Accuracy | | Less than or equal to ±10% | Repeatability | | Less than or equal to 6% | Power supply | | Built-in Lithium ion battery, AC adapter 5V,1000mA | Built-in Lithium ion battery, AC adapter 8.4V, 800mA | Dimension | | 112×50×47mm (L×W×H) | Weight | | approximately 360g |
