Thanks Dave,
Most importantly we need a simple testing device that is portable and easily used by any technician.
I have done some research and I think most important parameters are viscosity, TAN, TBN, water content and oxidization.
but do I really need all these in a purpose of go no go analyzer?
so finally I have com across PALL 500 which I think it is the most suitable analyzer.
Spectro has spread their measures over multi devices. it would be the best if they compile it in one device.
so any input of what are you using will be very helpful.
Regards,
