My "day work" is in the Natural Gas industry on production sites. Using anything electrical, like a camera with a battery installed is possible but it's a logistical nightmare; permits, extra people, gas meters, approval for each session of shooting ... all because it poses the very real risk of igniting gas that may be leaking.
This makes snaps close to impossible.
I want to solve this problem with a fully manual Nikon SLR, one that can at least shoot nicely without the battery installed and I'd also like the "T" setting for long exposures elsewhere in my life.
Any suggestions?

Any of the manual Nikons will work -- F, F2, FM, FM2. Also, the manual FT series Nikkormats.
But, here's a question that I'm embarrassed I don't know the answer to: Doesn't every camera with a flash connection, whether it's a hotshoe or plug, generate some sort of electrical impulse whenever the shutter is tripped? Or does there have to be an activated flash unit connected in order for there to be a current generated?

Great question, needs an answer.

And if you use camera without batteries, you would have to use handheld meter, and those use batteries too. Yes, there are meters without batteries, but for payed assignement can you trust on them or your head calculations?

On a simple mechanical camera with the single contact hot shoe (actually one center contact and one edge contact), the current is provided by the flash unit. The camera only operates a mechanical switch to complete the circuit, timed to coincide with the shutter opening fully.
