What CHOTEST does

CHOTEST (深圳市中图仪器股份有限公司) is a Shenzhen-based, privately held precision measurement instrument manufacturer founded in 2001 (formalized as a stock company) and operating from a headquarters in Nanshan District and a manufacturing facility in Bao'an District, Shenzhen. The company designs, manufactures, and sells metrology and testing equipment spanning nanometer-scale surface profiling to 100-meter-scale laser tracking, including coordinate measuring machines (CMM) in moving and fixed bridge configurations, intelligent vision measurement systems (VisionX software with AI auto edge detection), flash measurement instruments (VX series), laser interferometers (SJ6000, PLR3000), white light interferometers / optical 3D profilers (SuperView W1 with 0.1nm Z-axis resolution), confocal microscopes, roughness and contour instruments, thread comprehensive measuring machines, grating length measuring machines, machine tool probes (COMP series), and a range of calibration instruments for dial indicators, small angles, steel rulers, pressure, water meters, and sphygmomanometers. Core technology combines high-precision optical, mechanical, and electronic subsystems (helium-neon and fiber laser sources, white light interferometry, precision grating systems, servo motion control) with proprietary software featuring PTB-certified algorithms, 1% sub-pixel image processing, and 300+ feature parameters aligned to ISO/ASME/EUR/GBT standards. The company positions itself as a domestic Chinese alternative to imported brands such as Renishaw, Zeiss, Mahr, and Keyence, with a stated price-performance advantage.

The business model is anchored on hardware sales of precision measurement instruments sold primarily through direct enterprise field sales in China, supplemented by a nationwide dealer and agent recruitment program and an online self-serve channel for PowerDMIS coordinate measurement software trials. Revenue streams include instrument hardware (primary), one-time software licensing (PowerDMIS, VisionX), and professional services for on-site installation, training, and calibration. Customers span precision manufacturing verticals (machinery, electronics, molds, automotive, medical devices, watches), CNC machine tool builders, semiconductor and optoelectronics manufacturers, and government metrology institutes (Shaanxi, Wuxi, Suzhou), with academic adoption at institutions including the University of Science and Technology of China. Marketing is conducted through a content-rich bilingual website, a video center, technical articles, customer case studies, and participation in industry exhibitions such as CIMT. The company has received two disclosed rounds of institutional capital (Eastern Bell Capital and Rich Land Capital in 2023, China Reform Holdings Corporation in 2025) and operates at a 501-1000 employee scale with no public listing.
