(Yes, before my revision above, the substance was polite and correct (although maybe a little long))

Is this email polite and correct?

I really just had a pair of few opportunities to check the device (I'm not sure what you mean here, but do you mean your phone device? In that case, you can say: I only had a few opportunities to check my phone and have been unable to see your email) because now I'm assigned to another project. But However, let me introduce you with to Dr. M.R, who is the principal researcher and responsible for the TEM equipment. From now on, he is going to continue with the communications with the technical support staff of Geonics, expecting it can be successful in resolved resolving or the resolution of the functioning of the TEM equipment.

Best regards

This email is polite, and I've corrected some of your mistakes to make it sound better to whoever you're sending this to. I'm not sure what the context of the email is, so I can't change everything, but I hope this will help!
