Frequently asked questions
Which TIME TR model has the broadest parameter range?
The TR3220 covers the most parameters, including standard roughness metrics (Ra, Rz, Rq, etc.), profile parameters (Pa, Pp, Pv, etc.), and additional ISO measurements. This makes it most comprehensive for multi-standard applications.
What's the accuracy and repeatability difference between models?
The TR3110 offers ±15% accuracy with <12% repeatability. The TR3200, TR3202, and TR3220 all deliver ±10% accuracy with ≤6% repeatability, making them more precise for demanding inspection work.
Can I choose cut-off and evaluation lengths with these instruments?
The TR3110 has fixed cut-off options (0.25 mm, 0.8 mm, 2.5 mm). The TR3200, TR3202, and TR3220 add Auto cut-off selection and allow evaluation length choice from 1 to 5L, giving flexibility for different surface types.
What's the difference between the TR3110 and the higher-specification models?
The TR3110 measures only Ra (ISO) and Rz (DIN), making it ideal for straightforward coating or machining inspections. The higher models measure additional parameters including Ry, Rq, Rt, Rp, and profile metrics for more detailed analysis.
How do the models differ in weight and portability?
The TR3110 is the lightest at 200 g. The TR3200 and TR3202 weigh 440 g. The TR3220, despite being the most comprehensive, remains highly portable at 580 g.
Do these instruments use rechargeable batteries?
The TR3110 uses two disposable 3.6V Li-ion batteries. The TR3200 and TR3202 both use rechargeable Li-ion batteries. The TR3220 has a built-in Li battery, eliminating the need to carry spares.
