CHOTEST SJ5200 & SJ5500 Universal Thread Measuring Machines

Ensure perfect threads, every time. The CHOTEST SJ5200 and SJ5500 series are precision-engineered Universal Thread Measuring Machines, dedicated to the comprehensive and accurate inspection of threaded components.

These specialized systems go beyond simple pitch and diameter checks. They provide complete 2D profile analysis for a wide range of thread types—including metric, unified, trapezoidal, and ball screw threads—with exceptional repeatability.

The SJ5200 offers a robust and highly capable platform for standard thread measurement applications in quality control labs and on the shop floor. For the most demanding applications requiring ultimate precision and larger measurement ranges, the SJ5500 delivers enhanced accuracy and capacity.

Powered by sophisticated software, these machines automatically calculate all critical thread parameters:

• Pitch Diameter

• Major/Minor Diameter

• Pitch

• Flank Angle

• Lead Deviation

• Profile Form

With their robust construction, tactile probe sensing, and dedicated thread analysis functions, the SJ5200 and SJ5500 are the definitive solution for manufacturers who rely on the integrity of their threaded parts for performance, safety, and quality.

Summary:

Functions

• Full-automatic measurement for comprehensive parameters of cylindrical thread plug gauges, cylindrical thread ring gauges, taper thread plug gauges, taper thread ring gauges, plain ring gauges, plain plug gauges and other gauges with internal & external dimensions, including virtual pitch diameter, single pitch diameter, basic pitch diameter, major diameter, minor diameter, thread pitch, thread angle, half of thread angle, flank straightness, lead angle, taper, etc. 
• Can measure trapezoidal thread gauges, buttress thread gauges, sawtooth thread gauges and other large-slope thread gauges. 
• Can measure comprehensive parameters of single thread and multiple thread. 
• Can measure various thread gauges according to GB, ISO, BS, ANSI, DIN, JIS, API standards. With comprehensive and professional thread standards in database, it meets requirements of most customers. 
• Automatically generate test report according to selected standard. 
• After once measurement, the software can calculate various parameters of thread and display data of any position, it also could generate the thread curve, relevant parameters and analysis chart automatically.
•  Measuring probe and work holder are identified automatically, which avoids collision of measuring probe caused by disoperation. 
• One-sided or two-sided measurement and analysis for gauges. 
• Controller for measuring pin positioning: with an easy-to-use buttons control box, the operation is more flexible. 
• User-friendly software, simple and easy-to-use. 
• Test results are saved automatically with name of measuring series number + size of measuring gauge+ type of measuring gauge. With centralized database management for measuring records, the user inquiry and manage the measuring records according to object type, testing institution, manufacturing number, inspector, submitted institution, equipment number, inspection date, effective date, etc. 
• Can print multiple selected test records or test certificates from database at once time. 
• Can export test data to Word, Excel, AutoCAD (optional) files. 
• Data backup and restore. 
• Can output reports in a variety of formats in Word or PDF, moreover the report format can be customized.
• Support user-defined standards.
