Need a specific Hobbs switch

I need a Hobbs switch with a 2 terminal Metripack 280 connector set at .5 or 1 psi (best bet would be one of each). I've tried digging the epoxy out and adjusting a 4 psi switch but I have no way to test the psi other than in car on the drag strip (which eats up one of my 2 time runs each time I test it).

Anyone know where I can get such things?

Thanks!

The pressure switch that comes with the basic coolingmist meth inj kit ,is an adjustable switch, not sure if it will go that low though.

That's my problem, I have no way to know how much to adjust it or to check it.

Yea, but by the time I get all that and plumb it up I'm 50-100 bucks into a $25 switch. I need it to be fairly accurate, it came with a 4 psi switch, big lean spike, found a 3 psi, still same. I need 1 or .5, not +/- 2 psi.....

Same answer as above. Yea, I have a compressor, I don't have a bench boost gauge or a regulator to go to .5 psi.

I kinda thought one of our vendors might have either a switch or the equipment to test with accuracy. Maybe I was wrong?
