Engineers Who Ship Instruments, Not Brochures

RoyIntelli Instrument Technology Co., Ltd. is a professional manufacturer of coal, coke and biomass laboratory analyzers, based in Changsha — China's coal-instrument engineering hub.

Since 2009 we have designed and built automatic proximate analyzers, oxygen-bomb calorimeters, coulometric and infrared sulfur analyzers, CHN elemental analyzers, ash fusion determinators and moisture analyzers. More than 12,000 units now run daily in power plants, mine labs, commercial testing companies and universities across 40+ countries.

Our engineering team owns the full stack: DSP control firmware, thermobalance mechanics, high-temperature furnace winding and PC software with LIMS interfaces. That is why we can customize sample counts, voltage standards (110/220 V), chambers and reporting formats for OEM/ODM partners — and support every unit for its whole life.

We sell factory-direct. No trading-company markup, no blind handoffs: the engineer who answers your inquiry is the same team that builds your instrument.
