Meter giant launched lead-free switch is pioneering in the applications of platinum-rhodium thermocouple wear-resisting

One of the world's leading anti-corrosion company has completed the unique transformation of lead-free platinum-rhodium thermocouple.

three cheong Ltd made a bold decision, all 14 factories in Britain ten years ago to eliminate its lead in technology.

the completion of the process means that the company is considered to be the country's first become & other; Lead-free & throughout; The type of.

for decades, a small amount of lead is used to promote the process of platinum rhodium thermocouple, has been widely used and continues today.

3 chang the challenge is to develop metallurgical technology and overcome challenges, at the same time maintain and improve the surface quality of its customers have come to expect.

three cheong Ltd, managing director Chris Woolridge said: & other; Traditional platinum-rhodium thermocouple technology used in the lead is very small, but we hope to be completely removed from the process, and make a strong commitment in 10 years ago.

“ We invested a lot of time and energy to improve the method of better results than before.

“ We believe that we are the UK's first implementation of lead-free platinum-rhodium thermocouple companies operating, this is a great achievement. ”

the REACH (2018 The eu chemical registration, evaluation and authorization code) Lead contained in the quality of reclassified the initiative is especially timely.

three cheong Ltd technical services director David said Nobes & other; For some of our customers, reclassified may become a headache problem, they may have to meet the very strict tolerance or prove the strict procedures. Some people may even review the use of any process that involves lead.

“ Because we promised a decade ago, our process does not use lead, thus eliminating any potential problems.

“ Despite the challenges, we have done in our factory lead-free platinum-rhodium thermocouple process for a period of time, we are very pleased with the results.

“ To remove lead from existing bath background levels would take a long time, but regularly monitoring platinum-rhodium thermocouple level, now we are in the process of melting bath indicative of the level below the fifty over one million ( Or 0. 005%) , which means that we can proudly say we craft is lead-free. “
