Our History:

ESI (Efficiency Scientific Instrument Co., Ltd) was founded in 2010 to produce the high voltage X-ray power supply. From 2012, ESI started to develop and manufacture the X-ray tubes and DPP(Digital Pulse Processor). In 2019, ESI was merged with Htek instrument, which is a high technology company and a recognized leader in the design and manufacture of state-of-the-art X-ray fluorescence spectrometer.

Today, With combined technological experience and advantages accumulated in both companies over the past years, ESI is a worldwide market producer of advanced X-ray fluorescence system for complete solutions in elemental analysis with thousands of machines installed and operative all over the world. Every year high percentage of its revenue is invested in R&D with the aim to improve the analysis performance
