Hello Dear Group:


    I am very glad to see so many replies in the morning, and I am very grateful to every time nuts gave me useful information, your proposal has strengthened my determination, in fact, I am also very like SR625, So I will to find and buy a good shape SR625 for my new time interval measure instrument.


Thanks again for everyone's advice, which is very useful to make a choice for me. Sorry for not reply everyone's mail. 


Best Regards!
