APPLICATION

Surface Roughness Tester KR310 is a high accuracy instrument for measuring surface roughness. It can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc.

The KR310 allows surface roughness measurement both on metal and non-metal workpieces. especially for measurement on large and heavy workpiece, assembly line, on site. It is suitable for machining and manufacturing, quality control, inspection departments.

The KR310 is a Non Destructive Testing instrument, damage won’t caused to testing piece.

MAIN FEATURE

Mechatronics and ergonomics design, small size, light weight, easy to operation

The stylus drive unit can be stored within the main unit for standard measurement, or separated from the display unit by using the supplied cable which allows more flexible measurement in any orientation. The driver can be separated and reattached in one simple step

3.5 inches color graphic LCD touch screen, WYSIWYG, it includes a backlight for visibility in dark environments

It displays all parameter and graphic

The KR310 can be operated using the buttons or the touch screen

Measurement range up to 320μm

Large internal memory: 100 item of raw data and curves can be stored

The KR310 provides Bluetooth Capability , support wireless connection with mobile and mini printer

Built-in lithium-ion rechargeable battery and controlling circuit, high capacity, no memory effect

There is remaining charge indicator, charging hint

It works over 50 hours while fully charged.

Language: Chinese and English

DSP chip control and data processing, high speed, low power consumption

Real-time clock setting and display for easy data recording and storage

With auto sleep, auto power off, power-saving features

Reliable circuit and software design to preventing the motor stuck

All parameters or any of the parameters which set by users can be printed

Description

KS55 - Extending Rod, extending rod increases the depth for pickup to enter the part.  extending 50mm long.

KS90 - Right Angle Rod, change the position of the sensor, mostly use for measure surface of particular groove.

KS100 - Small Hole Sensor, measures flat surface, shaft ; when measure inner hole surface, the diameter of inner hole are required>5mm, depth>22mm.

KS110 - Curved Surface Sensor, to measure smooth cylindrical surface which radius is larger than 3mm, for the large radius smooth spherical surface and other surface also can obtain good approximation, need to work with platform KA520 or KA620.

KS120 - pinhole Sensor, to measure the inner surfaces of holes with radius more than 2mm, better to work with platform KA520 or KA620.

KS130 - Groove sensor,  measure flat surface,  groove surface with width ≥2mm, depth ≤3mm, and on steps with height ≤3mm, also to equipped with Measuring fixture, can measure cylindrical surface.

KS131 - Deep Groove Sensor, measure groove with width wider than 3mm and depth deeper than 10mm, or the surface roughness of step with height less than 10mm, also can used to measure the planar, cylindrical used with platform,better to work with platform KA520 or KA620.

KA520 -Metal Substrate Working platform, adjustable height 200mm.

With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

KA620 -Marble Substrate Working Platform, adjustable height 300mm.

With flexible and stable operation and wider application range. Roughness of complex shapes can also be measured. Measurement stand enable the adjustment of the position of stylus to be more precise and measurement to be more stable. If Ra value of measured surface is relatively low, Using measurement platform is recommended.

Height Gauge Adaptor, The best Measuring Fixture for split type surface roughness tester, easy to use.

Standard Roughness Calibration Block  Multi-engraved lines (Square Wave)

Made by optical glass, with high hardness, high accuracy standard roughness value, anti-scratch, has longer life than metal roughness block.

Meet standard GB/T19067.1-2003 and ISO5436-1:2000

Approximation: Ra=0.1um, 0.2um, 0.4um,  0.8um, 1.6um, 3.2um, 6.4um

Customized Value and Sine Wave available, welcome to inquire.

Standard Roughness Calibration Block  Single engraved lines

Made by optical glass, with high hardness, high accuracy standard roughness value, anti-scratch, has longer life than metal roughness block.

Meet standard GB/T19067.1-2003 and ISO5436-1:2000

Approximation: Ra=0.1um, 0.2um, 0.4um,  0.8um, 1.6um, 3.2um, 6.4um)

Customized Value available, welcome to inquire.

Roughness Comparator  (30 pcs/set)

This set contains standards of the six most important machining methods in the prevalent "AA" values. These surface roughness is used to compare and determine the degree of the surface finish by comparision method and eye estimation or magnifying glass.The surface rough contast blocks is made of 45 super carbor steel except the GCr15 which is using to plat lapping the sample block. All 30 speciments are calibrated in u''AA (Arithmetical Average) and in the metric equivalents um Ra.

Charge and Cable for Surface Roughness Tester

Charger: US and EU standard optional

Cable: USB interface

Mini thermal printer

External printer, connect by USB interface, suitable for Kairda models.

Thermal printing paper

Suitable for mini thermal printer and Kaidas’s tester with built-in printer

Packing: 10pcs/bag
