Description

Vintage Mercer Electronics panel mount "multimeter" meter.. Condition is "Used".
Clean, good condition.
Removed from a working RCA analog AM radio transmitter. This is NOT a stand-alone multimeter, it was part of a system where different monitoring points could be routed to it via a button panel. I don't know what it measures natively. Two scales on the face; 0-3 and 0-10.
It could surface-mount in a 2-3/4" round hole to a 3-3/4" round or square hole
without
the bezel or recess-mount in a 4-13/16 x 2-3/4" rectangular hole
with
the bezel.
Shipped with USPS Priority Mail.
