英國Index Instruments
Index Instrument公司是世界上第一家生產如此高精度折光儀并最先獲得由英國科技集團（BTG）授權執照的的商業公司。通過與英國物理實驗室（NPL）的通力合作，Index Instruments公司率先樹立起了這個行業的新標準，并成功生產出了世界上最高準確度的商用折光儀。
Index Instruments, have been making refractometers since 1975 and offer a wealth of experience in this specialised field of scientific instrumentation.

All of our equipment is designed with simplicity of use in mind. With their automatic control routines, even unskilled personnel can obtain quick, accurate results, freeing qualified technicians or chemists for
other work. Training time is minimised and maintenance costs are very low.

We spend a high proportion
of our turnover in a
programme of continuous research and development
to improve and innovate
our products.
